How to remove a jammed drill from a drill? How to change a drill bit in a drill - proven methods! How to insert a drill into an Interskol perforator

How do I replace the drill bit in a Makita drill? The question is simple, but it requires due attention, because if the drill is not properly fixed, then problems can arise: a broken or uneven hole, the probability of the drill falling out of the tool causing injury, as well as other troubles. Let's first look at how to insert a drill into a drill.

For correct operation, the drill must be fixed in the electric drill chuck with a shank. Most drills are equipped with a jaw chuck. These parts have a cylindrical body. A ring or a sleeve rotates along their surface, and cams are placed inside the cylinder, which, when the ring rotates clockwise, approach each other, compressing the drill. Counterclockwise rotation moves the cams apart, thereby relaxing the drill press. This allows it to be replaced or removed. It is necessary to relax the cams with some margin so that it is easy to insert the drill. The principle of operation of the cams makes it possible to mount drills of any diameter. Ordinary household drills are produced with a standard gap of the drill diameter - 0.8-10 millimeters, some models may have an interval of 1.5-13 millimeters.

There are two types of clamping: quick-release and key. In the first option, the rotation of the sleeve occurs manually. In electric drills with such a clamp, blocking elements are often used to limit the pulling force. In the second version, the adjusting sleeve moves due to the presence of a key. There is a hole on the side of the chuck where you can insert a key with teeth. Sometimes there are several such holes (up to three), each of them must be loosened by turning the key counterclockwise once or twice. Then they begin counterclockwise rotation of the chuck, thereby increasing the diameter of the hole for the nozzle. Now insert the drill and clamp first the chuck and then the nests.

To change the drill, you must first pull it out. Let's take a look at how to remove the drill bit from the drill. This process is quite simple, but you should be more careful, as you can damage the drill itself or the cartridge.

The procedure is as follows:

1. The equipment must be turned off first.
2. The drill must be carefully removed from the chuck using special keys. Pay attention to which cartridge is installed. If it is key, the key itself must be installed in the hole intended for it. Then the key is scrolled counterclockwise until the clamps disperse. Further, the drill can be easily pulled out, and a new one can be installed in its place.
3. If a keyless chuck is used, then you need to rotate the sleeve with the keys until the drill comes out (this requires effort, the drill must be held in hand). Hit the cartridge with a casual palm. If the drill is not tightly clamped, then it can be easily removed after such a movement.

If the drill is jammed, use force to remove the drill. This must be done carefully, otherwise the instrument may be damaged. The work is done as follows:

1. The equipment must be turned off first.
2. Then you need to gently tap the chuck with a hammer so as not to damage it. Place a plate between the hammer and the chuck.
3. Tap on the chuck until the drill shank comes out.

If an electric drill works only with metal chucks, then in order to pull out the jammed drill, you will need two gas keys. They are needed to clamp the sleeve, then the chuck must be rotated counterclockwise. This method can also be used for a plastic cartridge, but there is a risk of damage. If none of the methods helps, it is worth removing the cartridge from the equipment.

The blade of the drill may remain in the material that has been cut. You can tell if the drill is stuck by the characteristic sound. In such a situation, you must immediately turn off the tool, and then release the chuck.

The drill may not come out. In this case, take a new chuck and then gently pry off a small area near the stuck element with a drill. The "damaged" equipment is removed quite easily, for this it needs to be slightly rocked. If none of the measures helps, then contact the service center. Do not make great efforts, as the equipment may break.

Replacing the drill at the Makita drill is not so difficult, even if it is jammed during operation, you just need to choose the right models and cartridges. It is enough to do this work once in order to do it later without errors.

The hammer drill was invented in 1851 as a tool for the mining industry. In 1932, Bosch presented the first electromechanical impact hammer for construction work in Germany. Since then, Bosch Hummers have been mass-produced, and other companies have also acquired production licenses. The main functions of the rock drill are drilling, drilling and hammering. How to use a hammer drill correctly when performing various types of work?

The principle of operation of the punch

The innovative essence of the rock drill is that the impact force is generated by the tool itself. This happens due to the conversion of the rotational energy of the electric motor into the translational movement of the piston. The piston sets in motion the striker (striker), which already directly performs the work.

Depending on which tool is used, which mode is activated, the hammer drill can drill, drill or work in a jackhammer mode.

The rated power of the rock drill ranges from 1.5 kJ to 20 kJ. If we imagine that a 1 kg weight was dropped on the floor from a height of 1 m, then it will hit the floor surface with a force of 1 kJ. Accordingly, a 20-kilogram weight will hit with a force of 20 kJ.

Instructions for using the device

Rotary hammers are widely used in modern construction industry, they have replaced monotonous and ineffective manual labor. But its use is fraught with certain risks that you need to be aware of before starting work.

First of all, you need to work with a serviceable tool in a regular mode authorized by the manufacturer. The power supply must be provided through a cable with a cross-section suitable for the power consumption.

After transporting the rotary hammer in the cold season, to soften the lubricating fluids inside the mechanism, you must wait at least half an hour.

The operator performing the work must be healthy. Before work, it is necessary to study the instructions for the device and safety rules.

The main operating modes of the punch

Perforators operate in several basic modes, switchable by the operator, depending on the work being done.

Drilling

It is performed after switching the regulator to the corresponding mode (drill icon). The overwhelming number of models of rock drills are equipped with a function of a gradual set of revolutions of the working shaft. The speed is controlled using the start button. With a slight pressure, the revolutions from zero smoothly rise higher. When the button is pressed all the way, the revolutions become maximum.

Depending on the material to be drilled, it is recommended to adjust the speed of the drill or drill bit. So, wood products are best drilled at high speeds, metal at low speeds, and concrete or stone at medium speeds.

Most often, the hammer drill is used for drilling stone or concrete. This is due to the fact that the device of the chuck for fastening the drill has a backlash in the longitudinal axis, designed for the percussion drilling function. Therefore, when drilling holes in wood or metal, it is not always possible to achieve the desired accuracy. The drill tip may wiggle slightly.

It is recommended to use a chuck with SDS shank for precise drilling of holes. The drill without play is fixed in a chuck, which is inserted into the hammer drill. Jaw chuck included or sold separately. Any holes and materials can be drilled with a replaceable chuck.

In the drilling mode, you can use the hammer drill as a mixer for mixing various building mixtures - from paint to light plaster and gypsum compounds. The great convenience lies in the fact that the speed and direction of rotation are conveniently adjustable.

Drilling

The drilling mode is turned on by moving the switch register to the middle position (you need to select the drill and hammer icon). Usually indicated by the sign of a drill and a hammer drawn on the body at the same time. Drilling is used for slotting concrete and stone materials. It is possible not only to make holes, but also to lay ducts for routing electrical and other cables in plaster or brick walls.

Because drilling takes many different forms, engineers have developed numerous attachments to suit a variety of conditions. All of them are united by the presence of a special shank, which is combined with the SDS + chuck.

Hit

Impact mode is used for assembly and disassembly work. It is marked with a hammer icon on the mode switch. When working in this mode, there is no rotation of the working shaft. Only translational movement of the tool takes place.

Reverse

The reverse function allows you to switch the direction of rotation of the chuck in different directions.

Often, when drilling reinforced concrete structures, the drill rests against the reinforcement and enters a clinch with it. In order to release it, a reverse switch is provided, which makes it possible to turn the drill in the opposite direction and continue drilling, bypassing the reinforcement. Usually the reverse button is located directly next to the start button of the unit.

The reverse mode turns the hammer drill into a screwdriver, with which you can tighten and unscrew bolts, nuts and screws of any size and configuration.

Additional tool features

In addition to the above, the standard set of options in a modern rock drill include:

• a ruler to determine the depth of the hole;
• lever for fixing the operating position of the start button;
• safety clutch - stops the motor when the drill gets jammed.

And also in the design of each device there are systems:

• dust removal - impeller on the engine with a system of dust extraction channels;
• vibration damping - special springs between the housing and the power unit;
• electronic regulation of operation and monitoring of the condition of the brushes on the collector of the electric motor.

An important rule, non-observance of which can lead to failure of the hammer drill. Switching modes should be carried out only when the tool is completely stopped.

Rules for the safe use of the tool

It is permissible to use the puncher only with the use of personal protective equipment. These include goggles, earmuffs, gloves, and a respirator. Clothes should be free of fluttering long-length elements. Hair is gathered under the headdress. Shoes should be dry, comfortable and non-slip, preferably with socks reinforced with metal plates.

Attention. It is forbidden to work with a puncher in positions with an unstable fulcrum. Drilling kickback can throw a person off balance, possibly resulting in injury.

The noise level of a working tool fluctuates in the region of 100-110 dB. If the treated surface resonates (for example, a concrete wall), then the noise level can reach 140–150 dB. Such sound loading can lead to medical or mental health problems. Headphones or earplugs must be used.

How to insert / remove a drill or drill

To work with a hammer drill safely, you need to master a few simple skills. Mandatory skills include installing and removing a drill, drill or any other accessory.

Installation of the working tool

All rotary hammer drills are equipped with an SDS + type chuck that does not require keys. Unlike jaw chucks, drill installation takes seconds:

1. Pull the chuck base down.
2. Insert the drill shank into the hole.
3. Release the base of the chuck, the spring will return the chuck to its place, the locking ball mechanism will securely grip the drill in its metal embrace.
4. Check that the drill is securely fastened by pulling it towards you. The cutting tool must not be removed.

A properly installed drill should not protrude more than 1 cm from the socket when trying to pull it out by hand.

If a cam chuck is installed in the hammer drill, the drill can be fixed using the traditional method - by rotating the chuck body around its own axis until the thread is tightened.

Removing the working tool

To remove the drill or nozzle after work or for replacement, you must:

1. Wait until the rotation of the chuck has stopped completely.
2. Pull the chuck base down until it stops.
3. Remove the drill from the chuck.
4. Release the base of the chuck.

Attention! The drill gets very hot from friction. Use gloves to avoid getting burned.

Rotary hammer equipment

To get a more complete picture of the versatility of the rotary hammer, let's take a short excursion into the world of attachments that are used in the operation of this power tool. The main types of attachments:

• Boers. "Drills" designed for drilling work in stone and concrete. Reinforced with a carbide head at the end. The main purpose is to carry out installation work, fasteners, wiring communications.
• Crowns (cyphers). A device for cutting holes of large diameter. If it is necessary to make a hole of great depth, special adapters are used with the crowns, which allow the equipment to be extended to the required length. They are successfully used for the processing of ceramic tiles, in the installation of electrical equipment.
• Chisel. The most diverse category of rotary hammer bits. They differ in size, shape, length and width of the working surface. There are chisels in the form of a lance, in the form of a flat blade, as well as channel chisels (strobers), designed to gouge channels in concrete or brick walls. An irreplaceable assistant in dismantling work (removing old tiles, dismantling the screed, adjusting and leveling brickwork before plastering).

Photo gallery: drills, crowns and chisels

Drills for drilling in stone and concrete Crowns for large holes Chisels for cutting concrete and hammering grooves

All types of attachments are installed in the SDS + chuck in the same way, the fixation uses the principle of movable clamping balls. When properly installed, the rig can move freely along the longitudinal axis without falling out of the socket.

If the red LED on the rock drill control panel comes on, this means that the machine is operating above the rated engine load. Perform a technical inspection and eliminate the cause of the overload.

Where else can we use a puncher

The scope of the rotary hammer is not limited to work with concrete or stone. Wherever striking technique is required, this versatile apparatus can be used.

We hammer a pipe into the ground

Heavy perforators - weighing over 8 kg and blowing up to 20 kJ, are used when clogging an Abyssinian well. A galvanized pipe with a sharp tip is placed vertically and, using the hammer mode, driven into the ground. Of course, the diameter of such a pipe cannot be large (up to 1 inch). But even this is enough to provide an average family with water. This method is used when installing water intake in places inaccessible to heavy drilling equipment.

We ram the soil in the greenhouse

The use of a nozzle on a perforator for compaction of soil has proven itself quite well. It is a flat metal plate, which "trample" the ground. It is used on a local scale in the construction of greenhouses, arrangement of beds.

We mix cement mixtures

The main part of the rock drill is a rotating chuck. This is enough to instruct the hammer drill to mix cement screed or tile adhesive. All that is needed is to purchase a mixer attachment with an SDS + shank.

Summing up, I would like to note that this article is for informational purposes only. For complete information, refer to the instruction manual that each manufacturer provides with their products.

The tools produced by different companies have different performance and characteristics, there are features of operation. This must be taken into account when using the equipment during operation.

Mainly, the problem may be the inability to work properly with the drills. First, let's look at some of the differences between cartridges and drills.

Varieties

Drills are divided into used according to:

• wood,
• metal,
• glass,
• plastic
• tiles,
• concrete.

Drills can be:

• Spiral. They are versatile and can be used for drilling a wide variety of materials.
• Crowned. If depth adjustment is needed, this drill is used, which can make the hole large.
• Perovs. These drills are used to make holes in wood products.
• Stepped. They are used for drilling in ondulin, iron and metal tiles.
• Milling.
• Roughed and so on.

The drills also differ in their tip. They are specially made for impact and conventional drills, and are shaped like a cylinder.

As for the cartridges themselves, there are also differences. For example, some are used for a hammer drill and others for a conventional drill or hammer drill. In each case, the drill can be fixed in different ways.

You can find cartridges into which it is possible to insert drills for both a hammer drill and a drill. But for security reasons, it is better not to do this. The principles of operation of a hammer drill and a drill are very different from each other.

Cartridges, in turn, can also be of two types:

• quick-clamping,
• key.

The key chuck requires a special key to install the drill. The chuck is clamped with a key that is inserted into its hole and rotates clockwise. Thus, the drill is securely fastened. As for the quick-clamping, it is divided into two types: one-sleeve and two-sleeve.

The technique for replacing the cartridge is presented in the video:

The double-sleeve chuck has two couplings, one of them is clamped, the other coupling is twisted with the other hand. If we talk about single-sleeve cartridges, then the cartridge is clamped with one hand. The replacement of drills in such a chuck is much faster than in the key. But as for the fixation of the drill, it is much weaker with this option.

The drill is always mounted vertically, otherwise there is a risk of breaking not only the drill, but also the tool itself.

So how to insert the drill bit into a hammer drill or drill correctly?

How to insert a drill

For this process to go smoothly, it is important to follow some sequential steps:

1. Make sure the drill is unplugged before installing the drill into the drill.
2. Then insert the drill into the chuck. To do this, you must first make sure that the drill used is designed for a specific tool.
3. To reduce wear on the chuck on the hammer drill, you can lubricate the drill with a special lubricant. It can be applied to the hole in the chuck.
4. Next, secure the drill.
5. After installing the drill into the chuck, it is important to make sure that it does not wobble.

During the drilling process, do not touch the rotating elements of the drill or hammer drill. As you can see, the installation of the drill is not a particular problem.

It all depends on the cartridge you are using. But what if after work it is impossible to remove the drill from the chuck?

What to do if the drill gets stuck

Removing the drill from the chuck is usually not a problem. For example, in a key holder, it is enough to turn the key counterclockwise. In the keyless chuck, everything is just as simple. For this, the clutch turns counterclockwise. According to this principle, drills are pulled out from other types of chucks. But what if the drill is firmly seated in the chuck? This problem most often occurs with keyless chucks. It will take a lot of effort to remove the drill.

For example, the drill can be held in your left hand and casually hit the bottom of the chuck with the inside of your hand. Usually, after such actions, the drill is easily removed.

If the chuck is metal, you can also lightly tap the chuck with a hammer. It is necessary to tap until the tail appears from the cartridge. If this does not work out, then you can use the gas key.

If no manipulations help you, you will have to remove the chuck from the drill / hammer drill and disassemble it.

There are other times when the drill gets stuck in the wall. In this case, the drill is rotated in the chuck. To remove it, you will need to open the chuck and remove the drill from the wall.

So, as we have considered with you all the possible situations that may arise when working with a hammer drill and a drill when changing a drill.

See how to insert the drill into the drill correctly:

A drill and a hammer drill, as tools that make cutting elements rotate, are indispensable machines for construction, repair, installation of various equipment and other types of work. How to insert a drill into a drill and hammer drill? If this is not done correctly, then it will not be possible to work with the existing power tool and apply it in your activities.

The question, of course, is not difficult, but it requires due attention, since an incorrectly fixed drill can lead to problems: an uneven and broken hole, the likelihood that the drill will fall out of the tool, causing injury, and other troubles. First, let's look at how the drill is inserted into the drill.

How to insert a drill into a drill

For proper operation, the drill must be secured with the shank in the drill chuck. Most drills have a jaw chuck. Such parts represent a cylindrical body. A ring or sleeve rotates along the surface of the cartridge. Inside the cylinder there are cams, which, during the clockwise rotation of the sleeve, approach each other, squeezing the drill. When rotated counterclockwise, the cams move away from each other, relaxing the drill press, so that it can be easily removed or replaced. You need to loosen the cams with a margin so that the drill can easily insert.

The principle of operation of the cams allows you to clamp drills of any diameter. Household drills, as a rule, are produced with a standard allowable gap of the drill diameter - 0.8-10 mm. There is also another interval for some models - 1.5-13 mm.

Memo! When drilling tiles, the percussion mechanism must be turned off.

The clamping method is key and quick-clamping. In the first version, the adjusting sleeve is set in motion thanks to a special key. A hole is located on the side of the cartridge, into which a special key with teeth is inserted. Sometimes such a hole may not be one, but as many as three, and each of them must be loosened by turning it counterclockwise with a key. It will take one or two rotations, no more. Then we begin to rotate the chuck itself counterclockwise, increasing the diameter of the drill hole. Now, having inserted the drill, we first clamp the chuck, then the nests.

In the keyless chuck, the sleeve rotates manually. In drills and screwdrivers with such a clamp, locking elements are often used to limit the pulling force.

Before fixing the drill, you need to make sure that the machine is working. Then it must be de-energized, and after that the drill can be inserted.

You should never skimp on drills. A good drill will do the job better and will last longer.

How to insert a drill into a hammer drill

As in the case of a drill, before inserting the drill into the hammer drill, you need to make sure that it is working properly. Having put the tool in the drilling mode without a fight (left position), press the start button. If the sound of the engine is smooth and without jolting, you can fix the drill.

First of all, the drill shank must be properly lubricated and inserted into the chuck. It is better to use proprietary agents that protect metal parts from corrosion as a lubricant. We put the punch with a handle on the floor or on a solid surface, pull the back of the clamping device back and insert the drill all the way.

Memo! For drilling a concrete wall, it is better to use a hammer drill than a hammer drill.

When replacing drilling tools, pay attention to the shank, whether it is free of old grease and dust. The drills must be clean and free from sticking. If excessive friction occurs when the drill is immersed in the chuck, it is better not to rush to work, but to lubricate the mechanism with fresh lubricant in a timely manner, removing the old one, which has fallen on debris. The drill should run smoothly and easily.

During installation, the drill must be held vertically. Careless movement and incorrect attachment can damage not only the drill, but also the tool itself.

Chisels, mixers and other tools can also be used with the hammer drill. Whether you are going to do the job with a drill, or with another attachment, consider the power of the engine, whether it can handle a heavy load.

When working with a power tool, never forget about safety precautions. The necessary protective elements are special goggles, ear plugs or ear muffs and gloves. Work should be done in overalls that exclude laces, belts, and other hanging accessories that may wrap around the drill. Do not let the appliance go to waste for a long time. Switch it off after each completed work step. Rest the instrument, especially if you feel overheating. Usually the "schedule" is 30 minutes of work and 10 minutes of rest.

The drill must be inserted into the hammer drill chuck as far as it will go. Seeking to make the hole deeper by incomplete immersion of the drill is strongly discouraged.

If the drill gets stuck in the drill, you need to clamp it in a vice, and knock through the wooden bar with a hammer on the cams that do not release the drill. A drill stuck in the hammer drill can be pulled out by dropping a little oil into the key chuck, or by completely removing the chuck together with the drill and placing it in gasoline.

If the drill gets stuck in the wall, do not loosen the drill or hammer drill, as this may break it. Better to remove the drill from the chuck, insert another, and start smashing the wall around the stuck implement. Thus, it can be easily removed from the wall.

Summing up, we can say that if you correctly fix the drill in the drill and hammer drill, each step of the work performed will comply with safety standards and will help in solving the tasks and you will be able to drill holes correctly.

This video describes how to work with a hammer drill and shows how to insert a drill into it:

This video explains how to work with a drill, tells about the types of chucks and how the drill is inserted into them:

A hammer drill is an indispensable popular tool in everyday life, without which practically no repair can do. Before starting work with a hammer drill, you must insert a drill into it so that the tool is not damaged. The more skill the owner of the hammer drill has, the more perfect the result will be.

How to prepare a drill for installation in a hammer drill chuck?

Before inserting the drill into the hammer drill, you should prepare in advance not only the drill bit, but also a special lubricant and a chuck. There are many types of hammer drills, but there are also many types of drills. The use of one or another type of equipment will depend on the work that needs to be done before fixing the drill. Drilling can be done in wood or concrete, which influences the choice of the bit.

The accessory for the tool can be not only a drill, but also a crown or chisel. Any nozzle is designed to perform a specific operation. All attachments have a common characteristic related to the shape of the shank, which allows the tool to be securely fixed in the chuck.

You can insert a drill or other nozzle only into a working device, observing all the rules and safety precautions. Before inserting the drill into the hammer drill, carefully inspect the inventory to make sure it is in good working order and ready to go.

To this end, you will need to insert the plug into the outlet, selecting the mode with the regulator, which must be set in the left extreme position. This means that the instrument will operate in a non-combat mode. Then press the start button. When the hammer drill starts to produce sound that will be smooth, without interruption, then you can start working.

Drill Installation Safety

Important! If the puncher is checked in a timely manner for operability, then it is possible to exclude damage to the apparatus and possible injuries.

Observing safety precautions when changing the nozzle of the device or working with it, do not touch the rotating elements, as the result can be very sad. For this reason, the installation of the drill should be carried out in the chuck of the device disconnected from the socket.

If necessary, a chuck suitable for the existing tool must be purchased in advance. If you do not have experience in choosing this part, then it is best to take the hammer drill to the store so that you can easily and accurately navigate when buying a chuck.

The following types of cartridges are provided for completing modern models of devices:

1. Keyless.
2. Key.

The latter option is traditional, when the drill is clamped in wood using a key. This type of attachment attachment seems to be very reliable, but it is not as convenient as the method using keyless chucks. With the help of them, you can fix the drill without the use of additional devices. You just need to choose the option that is more suitable in order to follow the steps of the instructions for installing the drill in the future.

Which replacement drill to choose?

In order to do the work correctly, before fixing the drill, you should choose its type, since there are different nozzles. The correct choice will allow you to competently cope with drilling.

Be sure to pay attention to the color of the drill, which indicates a particular method of processing the nozzle. If the nozzle is black, it means that the drill was processed using superheated steam, and this does not affect the quality of the work. However, it is believed that if the drill is black, it is stronger. If the drill has a shade of golden or brown, it is tempered in order to relieve internal stress. The drills, which have a bright golden color, have been treated with titanium nitrile, which means they are durable and expensive tooling.

When purchasing a drill in order to install it in a hammer drill, it is important to pay special attention to all the characteristics of the nozzle indicated in the instructions. These include the brand of the attachment, as well as the material from which the attachment is made. If there is a strong heating of the drill during operation, then it should be concluded from this that it is blunt or poorly sharpened.

When replacing a worn-out drill inserted into a chuck with a new one, it is necessary to find out what type of chuck the chuck has: key or keyless. Therefore, the methods for removing old equipment may differ. Key cartridges are least of all exposed to various types of damage, since they are mechanical.

If the device has a keyless chuck, the tool must be switched to the reverse mode before changing the accessory. Next, you should fix the lower coupling, doing it with one hand, and unscrew the upper one with the other.

If the cartridge is single-sleeve, then its nozzle is replaced when performing operations with one hand. This is due to the fact that such cartridges have rotary hammers equipped with an auto-blocking shaft.
