Do you need a motor drill? Gasoline drill for excavation work: instruction manual. The best professional motor drills

While working in the garden or while carrying out construction work A gas drill is an indispensable tool that allows you to make a well quickly and efficiently. In the process of buying a gas drill, the main thing is not to make a mistake and make the right choice, while getting useful device, which will delight its owner long years. How to choose a gas drill for earthworks Let's look at it further.

Gasoline drill features and functionality

A gasoline drill is also called a motor drill; it looks like small device, capable of performing a wide range of earthworks. Exists a large number of gas drill models. They vary in power, weight, number of attachments and additional functions.

The principle of operation of a gas drill is reminiscent of an auger drilling rig. They allow you to build a foundation on piles, make holes for a well or a well. In addition, the motor drill is widely used in gardening for planting trees or bushes, constructing fences and enclosures.

The gas drill is easy to use and is also harmless to environment and landscape of the land plot.

A gas drill is widely used among those who like to go fishing in winter. They use it to make holes in massive ice.

The standard classification involves dividing gas drills into:

  • simple;
  • weighted.

The first option is used when performing work on sandy soils. They are characterized by less high power and light weight. With the help of simple motorized drills, it is possible to construct wells up to 200 cm deep. One person is enough to work with them, unlike weighted drills, which require at least two people when drilling.

Heavy gas drills are used on hard soils, this equipment refers to a number of professional equipment designed for working on the ground. The device is distinguished by the presence of a variety of augers and a three-act engine, which make it possible to make huge wells with a depth of more than five meters.

The peculiarity of a gas drill that distinguishes it from other types of drilling devices is that its main component is a gearbox. Its main function is to transmit movement to the auger, which carries out drilling. The type of gearbox used in a motor drill depends entirely on its type. A coaxial type gearbox is used in simple gas drills, and a worm gearbox is used in weighted ones.

Every buyer of a motor drill wants to pay a little money for a quality item, but saving only leads to a quick breakdown of the device. The price of gas drills for earthworks is influenced by their type. The cost of simple motor drills is less than that of weighted drills.

Benefits of using a gas drill

1. High level reliability is ensured correct selection equipment and calculation of its power.

2. No need for soil preparation and other equipment.

3. Possibility of drilling wells of various depths and diameters.

4. Obtaining high performance and power of the device.

5. The lightness of some models of gas drills allows only one person to carry out the work.

6. Compactness - the gas drill does not take up much space and is easily transported to Right place.

7. Using gasoline as fuel for a gas drill makes it independent of traditional power sources.

8. Reduced vibration level is another advantage of most gas drills.

9. Operational safety is regulated by special options that shut it down if problems occur.

10. The wide range of jobs that a gas drill can handle indicates its usefulness both in the construction industry and in gardening.

Main types of gas drills

Among the main types of gas drills, the following models should be highlighted:

  • manual type;
  • wheel type.

The first option is more common than the second. Since their cost is much lower, and their performance is satisfactory. The weight of wheeled motor drills is much greater due to their high power and the heaviness of the engine. Therefore, for their transportation they are equipped with wheels. The depth of the hole made using a wheel motor drill reaches 50 cm. Due to high cost they are in demand among professional builders.

Manual motor drills are designed to work with one or two operators. If you need to construct a hole up to 25 cm, a motorized drill with one operator is sufficient.

Wheel-type motor drills are divided into:

  • single frame;
  • modular.

In the first option, the motor and gearbox are located on the same block with the device itself. In modular motorized drills, on different trolleys.

According to the type of rotation transmission in a gas drill, they are divided into:

  • mechanical;
  • hydraulic.

A more reliable method is the hydraulic one, since the load is distributed evenly and the parts do not wear out as much. Therefore, when performing large volumes of work, you should use it.

To buy earth drill, you should contact a specialized store where experienced specialists will help you choose a model that is suitable for price and functionality.

When choosing a device, pay attention to:

  • the amount of power;
  • screw head size;
  • engine volumes.

To determine the power of a gas drill, it is enough to examine the label on which it is indicated. In addition, ask the seller for the operating instructions and technical specifications of the device, which contain all the information about it. The quality and speed of its work depends on the power value. It also affects its cost. Cheaper models are characterized by a minimum power of 2.5 hp.

When paying attention to the size of the auger, you should take into account the diameter of the holes intended for drilling. Some models have several auger options, while others do not have them at all. In this case, the screw head is purchased separately. The average size of the auger, which can cope with most household and construction work, is about 0.7-1 m.

When choosing the engine size of a gas drill, you should take into account the fact that it has a direct connection with the rotation speed of the auger located in the ground. The working size of the engine volume directly depends on the type of soil on which it will be used. For example, to drill a well in sandy soil It is enough to purchase a gas drill with an engine capacity of up to 35 m³ and a power of up to 2 horsepower. At the same time, when working on black soil, the engine volume must be at least 40 m³, and the power must be 3 hp. When processing compacted soils, the types of motor drills described above are not suitable; in this case, you need to buy a device with an engine capacity of about 200 m³ and a power of 5 hp or more. and higher.

Advice: When purchasing a gas drill, you should find out whether it requires fuel tank oil filling.

In addition, you should inquire about the presence of a fuse that ensures the safety of the person working with the gas drill. This happens as follows: when, during operation, the gas drill comes across a stone or tree root, the fuse automatically stops its operation. Otherwise, there may be a risk of injury or injury from using this device.

The operation of gas drills requires careful care of the device; first of all, the fuel that is poured into it must be of high quality, and the knives located on the auger head must be sharpened. This fact prevents premature wear clutch and gearbox. To store the gas drill, use a room protected from moisture.

Gasoline drill for excavation work: instruction manual

The first and main rule quality work A gas drill is the use of augers that are suitable in quality and diameter for the type of soil on which the work is being done. Otherwise, there is a possible risk of not only breaking the gas drill, but also injuring the driller himself.

To reduce the effort in the process of starting the device, there is a special system called easy start. With its help, the gas drill is heated, thanks to its work on idle speed within 3-4 minutes.

The place where drilling is carried out must be cleared of debris, large stones and other objects that interfere with drilling. Start drilling by installing the drill, then you should position yourself more steadily so that the rotating auger is as far away from you as possible. Hold the motor drill with both hands and start working.

The most lightweight material for drilling is ice. Although you should be extremely careful in the process of drilling it, as there is a possible risk of cracks appearing on its surface.

When working on soil soils, it is necessary to periodically lift the auger from the well to remove chipped material and prevent jamming. When jamming occurs and the risk of injury is reduced, open the inertial clutch chain by fully releasing the gas.

It is prohibited to drill holes deeper than the length of the auger. If it is necessary to equip such a well, you will need to purchase an additional extension.

A substance containing gasoline and oil in a ratio of 1 to 40 or 1 to 50 is used as fuel for a gas drill. When running in the engine, the solution is prepared in a ratio of 1 to 25.

There are two types of gearbox:

  • coaxial;
  • worm.

The clutch is located in the space between the engine and the gearbox. When using a gas drill, you should pay due attention to the knives, as they affect the wear of both the clutch and the engine.

One person can easily cope with work on a drill with a coaxial type of gearbox, since its weight is light and it spreads along the drilling axis. Worm gear models require multiple people to drill.

It is not recommended to use gas drills when drilling ice, as at this time they are susceptible to influence negative temperatures, which affect the quality of the device. For these purposes, use special hand drills designed to work in such conditions.

Maintaining safety when working with a gas drill

Majority modern manufacturers Gasoline drillers care about the safety of the person working with this device. Almost all models have a function that provides emergency stop drilling This system starts working when the motor drill collides with an area of ​​soil that is impassable.

Additional features of some models include special locking levers that prevent accidental starting of the device. In addition, convenience and ease of operation is ensured by the presence of a handle.

Manufacturers of high-quality gas drills make sure that even during a break in its operation, propulsion system did not give in to wear. Thanks to the presence of a special microporous coating, lubricant is supplied to the engine, increasing its service life.

Review of gas drill manufacturers

There are two types of gas drills:

  • household;
  • professional.

The first option is suitable for infrequent use; such models are usually made in China. Their cost is affordable, but their quality is low. But, if necessary, for periodic use, and for the purpose of saving, purchasing such a gas drill is quite acceptable.

More high quality Products of the middle and high price categories differ. Among such motor drills, Hitachi, Efco and other manufacturers stand out. They belong to semi-professional equipment. They are suitable for private construction or small organizations that require periodic use of drilling devices.

TO professional equipment Manufacturers such as Stihl, Husqvarna and Echo should be included. These gas drills are most often used by companies that rent them or in businesses that constantly use gas drills.

We invite you to familiarize yourself with the main manufacturers of gas drills:

1. Hitachi - Japanese-made gas drills that have the following features:

  • high quality and versatility;
  • average price category;
  • using an engine with the NewPure Fire system;
  • variety of models;
  • possibility of adjusting the angle of the handle;
  • the presence of a system that ensures smooth and soft startup of the device;
  • light weight.

2. Efco - these gas drills are produced in Italy. The devices differ in the following characteristics:

  • excellent for constructing wells for planting trees, for installing fences and fences;
  • the location of the controls is one-sided;
  • Thanks to the presence of foldable handles, there are no problems with transporting the gas drill;
  • Availability circuit breaker blocks the operation of the gas drill in case of emergency;
  • The package includes an adapter and drilling pins.

3. Stihl - the country producing these gas drills is Germany. They differ in the following features:

  • mobility and reliability;
  • ease of operation and maintenance;
  • the variety of models allows you to choose a device that suits each consumer;
  • stable engine operation ensures highly efficient results;
  • strong traction allows drilling on soils with high viscosity;
  • to reduce the load on the operator and for uniform drilling, handles with anti-vibration properties are used;
  • the presence of a braking mechanism ensures the safety of the operator working with the gas drill.

You can carry out excavation work on the site different ways. Previously, conventional equipment was used for these purposes, such as shovels and picks. Now they use much more advanced mechanisms.

Motor pumps, motor drills and other mechanized equipment come to the fore. And this is not surprising, because a motorized drill for excavation work is capable of delivering truly unique performance. With hand tools and own strength You won’t be able to achieve such results in such a time frame.

1 Purpose and design of a motor drill

Motorcycle pit drills work using a fairly simple, but at the same time effective technology. In fact, it is not much different from the technology that is used when using a regular one.

Homemade pit drill- This is an interesting tool that allows a person to develop the soil on his own. It consists of a rod, a special handle, a welded screw and several other parts. The drill can be untwisted, the handle changed, lengthened, etc.

Its operating principle is quite simple. By rotating the handle of the hole drill, you also rotate the auger welded at an angle. He, in turn, cuts off the soil layer by layer. Well, the inner core prevents it from going in any direction.

In this way, you manage to cut the soil step by step in the right place and form a hole of a certain diameter. Reviews of manual hole drills indicate that they can be used to make holes with a diameter of 150-200 mm without any problems.

You can also control a motor drill with your own hands. In principle, this is what it is intended for. Only here it’s already your own physical strength the work doesn't cost. In gas drills, the internal combustion engine takes on the entire load.

It runs on a mixture of oil and gasoline, which, by the way, is very useful. After all, such a mixture wears out the engine less and makes the device more durable. Motor pumps operate using a similar system. Only motor pumps are not intended for drilling, but for pumping out liquids. However, we will mention motor pumps a little later; now we are talking about motor drills.

Standard single-seat motor drill with a large auger, diameter 250 mm

Drilling with a motorized drill, due to the presence of an engine, is much faster and of better quality. In fact, the difference in speed is simply amazing. The depth of development also matters, but there the difference is still not so felt.

One has only to remember that the auger of a motorized drill is capable of going 50-80 cm deep into the ground in a few seconds, and this is without exaggeration. And here is a homemade auger from hand drill or even branded hand tool from the Shtil company or other similar manufacturers will give you the opportunity, with due diligence, to go deeper to the same mark in 10-20 minutes.

And the depth will be covered only if you worked hard and did not encounter any troubles along the way. For example, a large boulder or something similar.

It is quite obvious that a well with a motorized drill will be developed much faster. In fact, a two-seater well with an extended auger will develop a well with a diameter of 150-200 mm in 1-2 working days. Then all that remains is to apply it. A motor pump is needed to pump out dirty liquid.

Motor pumps, unlike standard pumps, dirt and large inclusions are not afraid. The motor pump is capable of flushing out mud flows with high efficiency, while even high-quality drainage pump It will simply get clogged and refuse to continue working. After pumping, the well will be ready for operation. And this process will only take a day or two.

All this will give you a good motor drill; with your own hands and with the help of available tools you can cope with similar tasks, in the best case, in a working week.

The motor drill auger is also slightly different from the standard one. It looks like a metal spiral that is welded onto the central rod. But the auger for homemade hand-made samples consists of only a few sawn disks that are welded onto a rod at a certain angle.

The advantage of a factory auger is that it is able to pull the developed soil out and, thereby, significantly simplify a person’s work. It is worth noting in advance that everyone has their own auger. Popular manufacturers, such as Calm, Champion, etc. try to use personal equipment standards.

There are several reasons for this, but all you need to remember is that there is very little unification of standards. Therefore, if you are going to buy equipment from the Shtil company, then you will also have to buy augers from the Shtil company. Otherwise, you simply will not be able to attach them to the drill rotor.

1.1 Types of motor drills for excavation work

Motor drills are produced in several configurations. The main differences are revealed when considering the specific characteristics of equipment of this type, but this is not always the case. There are also significant points in the design of the devices themselves. We'll talk about them now.

First of all, drills are divided according to the type of engine into:

  • Two-stroke;
  • Four-stroke.

These are the simplest, but at the same time the most effective engines. They are capable of delivering sufficient performance with relatively low fuel consumption. And what is very important is that anyone can handle a machine of such power.

Two-stroke models, as a rule, are weaker than four-stroke ones, but they consume less fuel and also weigh an order of magnitude less. It is worth understanding that it is not always necessary to buy the most expensive and productive unit. Thus, a four-stroke engine is practically not installed on small-sized augers with a diameter of 150 mm.

2 Reviews of motorized drill for excavation work

It is worth considering the specific characteristics of the motor drill, as well as their special properties or functions. It is worth understanding that the choice of such equipment is always carried out by analyzing their characteristics. The visual side plays a minimal role. For some, it doesn't matter at all.

First you need to understand the motors in gas drills. They can have different power. Moreover, it is described both in kilowatts and in horsepower.

Usually, medium model single-seat type has a power of 1.5-2 horsepower. For example, the Shtil VT 45 gas drill is capable of producing 1.8 hp. This power is sufficient to perform the vast majority of work related to domestic or construction drilling.

To develop wells or more serious processes, you need to use double models, the power of which reaches 3-4 horsepower. But, as mentioned above, such equipment is not always worth buying, especially if you just want to have it to help you, and not as a professional tool, which will help you in your work.

The number of revolutions of the motor drill engine is also taken into account. It affects specific operating moments of the device. The weight of the drill is 7-10 kilograms for single-seater models and 16-21 kilograms for double-seater models. However, there are exceptions.

You should also pay attention to additional features of the motor drill, its properties, functions, etc. Every company wants to surprise its customers and attract them with something special, so such things should not be ignored.

Now let's look at the reviews about the motor drill for earthworks.

Andrey, 48 years old, Rostov:

I used a motor drill Shtil VT 45 for winter fishing. The most beautiful thing for your money. I read reviews from other fishermen and realized that it should be taken without delay. And what’s more, the machine is great for working around the house, garden, etc. I recommend to everyone.

Mikhail, 32 years old, Vitino:

At one time, my friend and I used a two-seater motorized drill to create a well in drinking water. I'm still happy with the result. I had to work a little, but now I get water on the site, which I produced with my own hands. And this is not only useful, but also pleasant.

2.1 Operating principle and features of using an earth drill

The motor drill is powered by an internal combustion engine. Moreover, this engine has a fairly high efficiency, as for equipment of this type. The engine has one cylinder, which transmits force to the rotor or attachment. Here everything depends on the specific device model.

The attachment then rotates the auger itself. If the motor drill has a rotation control function, then the attachment will be equipped with simple gears.

When you press the button, the drill operates at a fixed speed. A person only needs to install it in the right place, apply pressure during direct work and control the entire process.

If the device has several speeds, then more is needed. professional approach. So, when working with soft soils, it makes sense to speed up the speed in order to pass the area easier. But it is better to pass on hard soils with greater effort, but at lower speeds.

To improve safety precautions and prevent unforeseen circumstances associated with unauthorized rotation of the rotor or blocking of the drill in the hole, safety handles are mounted on the tools in question, which automatically turn off the engine if the fuse collides with an obstacle.

2.2 Testing a double gas drill (video)

The power auger will do its job underground, but an important part of the drilling job—making sure the operator and bystanders are not in danger—begins before the power auger touches the ground. This article is needed primarily so that, having rented a tool, you would remain in good health and return the equipment to in good condition and without traces of blood :)

During construction and repair work Tasks may arise related to the movement of goods around a room or territory and require the use of special equipment. The stacker rental section presents models of stackers for rent, as well as prices and rental conditions.

It may seem obvious, but safety is paramount to avoid injury, some of which can be serious. Drilling is fraught with dangers, and while manufacturers strive to produce tools that are as safe as possible, it is a good idea to learn operating standards and stay up to date with manufacturers' recommendations to keep yourself and others safe.

Sometimes it's easier to call

Knowing the area where work is being done is the first, or even zero, step before drilling begins. Danger may lurk just a few tens of centimeters below the surface, where communications may be laid. If you hit them, problems are guaranteed; this can result in monetary losses or, in the worst case, serious injuries. The most dangerous options are to touch a power line or gas pipeline, in which case you can get an electric shock, fire, burns and other troubles, even fatal. If you have the slightest doubt, it is better to call local networks and find out if this or that type of communications passes through your area. Once you have verified that there is no potential threat or have marked areas that cannot be drilled, you can begin drilling.

Before starting work, check yourself and the gas drill

  1. To protect himself, the operator must wear protective equipment and follow the simplest dress code when working with a motor drill. Don't wear sandals; opt for work boots or at least sneakers.
  2. Avoid wearing loose, loose clothes and watch your laces. If any of this gets into the auger, it won't be pleasant. To protect against flying dust and debris, wear safety glasses and gloves when the auger is running.
  3. Read the instructions for the gas auger before starting. Even if you have a lot of experience with power drills, different manufacturers implement safety features differently, which vary from model to model.
  4. After reading the instructions, carefully check the gas drill to see if any repairs or replacement of damaged parts are needed, or if anything broke off during transportation.
  5. Make sure the kill switch buttons and wires are not damaged and are properly connected and functioning.
  6. To make sure the throttle is working properly, start the engine and let it run for a few seconds before releasing the throttle. If everything is working normally, the engine will automatically return to idle.
  7. Next, check the gearbox and tighten the bolts. Check the handles and body for cracks or other damage.
  8. Poorly secured knives can lead to increased vibration of the gas drill and its wandering during operation, so before starting, check the fastening of the knives and, if necessary, tighten them. Don't get hurt by sharp edges! If you are installing knives on a gas drill for the first time, use the manufacturer's instructions.
  9. If you are working with a gas auger that has a reaction arm to protect against kickback, connect it correctly. The bar is installed differently different manufacturers, so follow the instructions.
  10. Finally, be sure to check your oil, fuel, or hydraulic fluid levels. After the engine warms up, it will be more difficult to replenish the fluid level, gasoline will ignite when it comes into contact with hot metal, and so on. Therefore, it is easier to do this before starting work.
  11. If all the previous steps have been completed, then the operator’s safety is now in his own hands.

  • When the tedious part of preparing yourself and the gas drill for work is over, you need to remember about those around you. Do not let anyone come closer than 3 meters when starting the gas drill.
  • When the auger is running, position the auger perpendicular to the ground for better control and optimal results.
  • Tip: For better control, vary the auger pressure depending on the soil. On soft soil, do not press too hard on the auger; on heavier soils, apply a little more power, but not so much that the rotation stops and the engine stalls.
  • The main tip for working with a motor drill is to pull not with your back, but with your legs. It’s easy to strain your back when working with a gas drill, so put the load on your legs.
  • When you have reached the desired depth, you should remove and stop the motor drill correctly. Since the auger rotates with high speed, never pull it completely out of the hole until the engine has stopped. Even an experienced operator may not be able to handle the gas drill in this case. When removing the gas drill, release the gas and allow the engine to stop. Only after a complete stop can you get the gas drill out of the hole.
  • If the auger gets stuck in a tree root or hard soil, stop the engine and disconnect the auger. Rotate it counterclockwise to release it. Sometimes this requires an adjustable wrench. In the most extreme cases you will have to dig out the auger.
  • If you are holding a gas drill in your hands for the first time in your life, take your time and do not press hard on the gas. By working at low speed you will master basic skills and understand the mechanics of the process. And don't get hurt in the process.

Choosing a motor drill

What do you need to know to choose the right motorized drill for poles?

To choose the right motor drill for poles, you need to know the diameter of the holes, drilling depth, season for work and the type of soil in which drilling will be done. Always pay attention to the technical characteristics of the motor drill. Especially for the maximum possible drilling diameter. When drilling with the maximum possible drilling diameter, the motor drill always operates at the limits of its capabilities and has no power reserve. Therefore, with the specified maximum drilling diameter it is possible to drill to a depth of no more than 1 meter and only in light soils not higher than the second category.

Hydraulic motor drills with power 11 and 15 hp. capable of drilling to a depth of more than 1 meter with a maximum diameter. For drilling category 3 soil, with diameters of 350 mm and above, we always recommend hydraulic motor drills with a power of 11 hp or more.

What is the difference between hydraulic and mechanical motor drills?

A hydraulic motor drill has higher reliability and service life, more power and torque compared to any mechanical motor drill in a design that uses a large number of parts working under conditions of strong friction.

On another site they offer me a cheap motor drill for drilling frozen soil. You are offering me an expensive hydraulic motor drill. Why?

No mechanical motorized earth drill is designed for drilling frozen soil. Frozen soil is a kind of natural concrete that is very difficult to drill. The gearbox of any mechanical motor drill is not able to provide the required torque. It is worth noting that some mechanical motor drills are sometimes capable of drilling in frozen soil, but with a drilling diameter of no more than 150 mm and when used within Middle zone Russia. These are Ground Hog 1M, Ground Hog C-71, Stihl BT 360, Efco TR1585, Oleo-Mac MTL 85. And these motor drills are also quite expensive. If you don't believe me, buy it and try it.

Which maximum depth Is it possible for drilling with your motorized drills?

This depends on the diameter of the auger, the category of soil, the cutting knives used, and the type of extensions used. As standard, ANY of our motorized drills with an installed auger drill makes in the soil of the second category (see the section “Soil categories”) the maximum hole specified in technical specifications motor drill, to a depth of 1 m.

The hardest thing about drilling to a depth of more than one meter is lifting the waste soil from the hole to the surface. Therefore, follow our recommendations when drilling:

Never try to make a hole in one pass, otherwise you will bury the auger and will not be able to get it out.

Make a hole one meter deep ( full length auger drill). Go deeper gradually to a depth of about 30-35 cm, lift the drill from the hole and, including rotation, remove the earth from the drill. Once the one meter deep hole is prepared and cleared of soil, clear the excavated soil from the edges of the hole, disconnect the auger from the gas auger and lower the auger into the dug hole.

Connect an extension cord to the auger drill, connect a motor drill to the extension cord and start drilling to a depth of more than a meter. For drilling to a depth of more than 2 meters with a diameter of 250 mm or more, we recommend using auger extensions, which will significantly facilitate your work and will quickly lift the excavated soil to the surface.

Clear the auger from the soil, attach the extension, lower the extension with the auger back into the hole and connect the motor drill and continue to go deeper into the next part of the hole, 30-35 cm deep. Continue drilling with this method, lifting the auger with the extension out of the hole and lifting the earth, until you reach the desired depth.

When drilling deeper than 2 meters, always use a tripod and auger extensions that can lift mined-out soil to the surface. Simple extensions without a flange (without a spiral) will not be able to lift the earth to the surface, and the operator will never lift a motor drill with an auger and extension above his height. If you are using a simple extension without an auger, to make the job easier, use a tripod with a winch to lift the ground.

When using a tripod, always keep the winch cable taut to prevent the auger from unexpectedly drilling into the ground. The greater the drilling depth, the greater the weight of the installed augers and extensions, as well as the mined-out soil. Sometimes this can be more than the operator's weight. Therefore, a tripod is needed, without which the operator will not be able to control the motor drill and will not be able to lift the augers and earth to the surface.

Which protective systems Are there gearboxes in mechanical motor drills?

Any mechanical motor drill except Iron Mole C7 does not have such protection. The risk of breaking the transmission of a mechanical motor drill due to worn knives or jamming of the auger in the ground is very high. As a rule, when overloaded, the clutch quickly heats up and smoke appears. If you don't stop, the clutch will burn out and will need to be replaced. Following the clutch, the gearbox will break.

In the Iron Mole C7 mechanical motor drill, there is a V-belt between the gearbox shaft and the motor shaft, which, in case of overload, slips and protects the gearbox and clutch from damage.

Hydraulic motor drills have overload protection. Hydraulic motor drills do not have a gearbox or clutch. The screw rotates using oil under pressure created by an oil pump. If the auger is worn out and jammed in the ground, excessive pressure occurs. Under its influence, a safety valve in the hydraulic distributor opens, oil flows through it past the hydraulic motor and excessive pressure quickly drops. But if the hydraulic distributor is not adjusted, then the risk of breakdown remains.

I need a depth of 5 meters, can your motorized drills do this?

Yes they can. According to reviews of motor drills from our clients - the best choice For such work, hydraulic motor drills. Especially Iron Mole M series. The transmission of mechanical motor drills is weak for drilling over 2 meters. You also need to consider not only your technical task, but also the capabilities of motorized drills. The larger the drilling diameter, the shallower the drilling depth and vice versa.

To drill more than 2 meters, it is necessary to use auger extensions and a tripod with a winch, so that the excavated earth rises to the surface from the entire depth. It is almost impossible to use extension cords without augers for such work; it will be very difficult to lift the excavated soil to the surface.

A motorized drill is required for drilling water wells. Which one do you recommend?

Motorized drills are NOT INTENDED for drilling water wells.

This requires special equipment that is capable of lowering, rotating and lifting a drill string weighing about a ton or more to the surface. In addition, for high-quality water drilling, it is necessary to flush the well from sludge during drilling. When drilling for water in the ground, there are layers or stones that even a powerful car-based drilling rig cannot penetrate, and in this case, percussion-rope drilling may be required.

The power and torque of a motor drill for drilling water wells is simply not enough, and the operator will not be able to lift the drill string to the surface.

You need to drill frozen soil, which of your motorized drills can do this?

Only hydraulic motor drills. Only they have the necessary torque and power. For the right choice hydraulic motor drill, in addition to the type of soil, you need to know the depth and diameter of the drilling.

Drilling with a motor drill

When drilling into plastic clay, it sticks to the spiral of the motor drill. How to make drilling easier?

Drilling plastic heavy clay is a very difficult job. Especially if the drilling diameter is more than 300 mm and the depth is more than 2 meters. Even hydraulic motor drills have a hard time doing this job. To make work easier and reduce the load on the motor drill, lubricate auger drills and extensions with machine oil. Clay will stick to the augers significantly less, the load on the motor-drill transmission will decrease, and the rise of soil to the surface along the augers will speed up.

How to drill clay correctly with a motor drill?

For heavy drilling clay soil We recommend using carbide cutting knives. Before drilling, ESPECIALLY IF THE SOIL IS FROZEN, if it is very difficult for the auger to enter the soil, crush the entry point of the drill to make drilling easier. When drilling, use the rocking drilling method, that is, when drilling, DO NOT try to hold the auger axis (drilling axis) at a 90-degree angle to the surface. Instead, briefly change the angle of the drilling axis to allow the blades to better grip the ground. Whenever drilling into heavy clay deeper than 1.5 meters, use a tripod with a winch to lift the auger bits.

I came fishing, started a motorized ice drill, and made several holes. Then he put the ice drill in the snow and started fishing. After an hour and a half, the ice drill could not start. What could be the problem?

After work, the motor drill is still hot, you put it in the snow, the snow under the motor drill began to evaporate and the moisture from the evaporation that got into the carburetor froze. The problem can be easily solved. Open the lid air filter Sprinkle some gasoline into it and the engine will start without problems. After work, install the motor drill in vertical position so that snow and moisture do not get into the engine and freeze. Also check the quality of the fuel, poor quality fuel with high content water may freeze in the carburetor.
