Peorator drill: how to insert, remove, secure

With the advent of reinforced concrete structures, it is impossible to carry out exterior and interior repairs without a pen. On the market there are a large number of models from different companies, these are Bosch, Makita, Sturm, Zubr, Vihr, Dexter, Interskol, Kalibr, Metabo, Soyuz. In spite of the variety, the basic units and mechanisms work almost identically. The process of re-setting the workpiece is also similar. Before inserting a drill into the peorator, one should know how to take it out correctly.

The peorator is a versatile tool that has a lot of possibilities. It has a pneumatic device inside that pushes the piston in contact with the striker. The latter causes the tool to reciprocate. As a result, the nozzles destroy any surface. The presence of the impact function allows the tool to make holes in hard materials.

Its purpose depends on the built-in modes: drilling, chiselling and drilling. There is a toggle switch for switching modes.

Manufacturers produce models of different weight :

The power and impact force depends on the size of the chuck.

Correct setting of the drill in the drill chuck

Before figuring out how to insert the drill bit into the chuck, it is advisable to figure out how to insert the drill bit into the drill. The element of its design, in which the drill shank is fixed, is the chuck. Most models of modern drills have cam-type chucks, consisting of:

  • cylindrical body;
  • Rings or sleeves, which rotate around the outer surface of the body;
  • cams mounted on the inside of the housing.

When rotating the sleeve clockwise, the jaws simultaneously approach each other, thereby securely clamping the shank of the drill bit to be installed. Accordingly, the question of how to remove the drill bit from the drill is not difficult to solve: Just start turning the sleeve counterclockwise. In doing so, the cams will begin to separate, making it easy to remove the drill from the drill. Please note that before inserting the drill bit, the jaws must be unclamped with a reserve, so that the tool can be inserted easily.

The convenience of using cam-type chucks is not only in the efficiency and high reliability of the tool installation, but also in the fact that they can be inserted drills of almost any diameter. When using such chucks, difficulties with how to change the drill bit in a drill, as a rule, do not arise. A properly inserted tool holds securely in these chucks and allows you to drill a precise hole.

If you notice your jaws slipping when you tighten the chuck, replace the wrench with a new one

Jaw chucks are used in both industrial and power tools for drilling. The jaws of domestic drills are available in two drill diameters from 0.8 to 10 and 1.5 to 13 mm.

Jaw chucks can be designed with two different ways of clamping the tool: with a wrench and a quick-action clamping.

In the first case, the sleeve is actuated by a special wrench, which has teeth on its conical working part. The key to actuate the clamping mechanism must be inserted into the holes on the side of the chuck body and rotated. There can be even three such holes in certain models. Accordingly, to loosen or tighten the cams, the key must be inserted into each of them and start turning counterclockwise or clockwise.

After loosening the jaws, use a wrench to turn the chuck itself counterclockwise to increase the distance between the jaws to the required value. If a tool is inserted, it is blocked in the reverse sequence: first the chuck is closed (clockwise rotation) and then the sockets are closed with a spanner.

Pulling out and setting the drill bits in a quick-action chuck is much easier and quicker. With a quick-action chuck, the shell is actuated by turning it manually. To limit the pulling force of the jaws, they are often equipped with a locking mechanism.

Before reinserting the drill, first make sure the drill is in working order and turn off the power. Only then can the drill bit be inserted.

What to do if the drill bit jams

Drill bit jammed

Usually removing the drill bit from the chuck is not a big problem. In the keyhole chuck, for example, just turn the key counterclockwise. With a quick-action keyless chuck, everything is just as easy. To do that, you twist the socket counterclockwise. This is how drills are removed from other types of chucks. But what to do if the drill bit is firmly seated in the chuck?? This is most often a problem with quick-action chucks. Extra effort is needed to get it out.

For example, the drill can be clamped in the left hand and the inner side of the palm slanted against the bottom of the chuck. Usually after this action the drill bit comes out easily.

If the chuck is made of metal, you can also tap it lightly with a hammer. It is necessary to knock until the tail of the drill bit comes out of the chuck. If this does not work, you can use a gas wrench.

If this does not work remove the chuck from the drill/tool and take it apart.

There are also other cases when the drill bit gets stuck in the wall. In this case, the drill bit is twisted in the chuck. To remove it you have to unclamp the chuck and remove the drill from the wall.

So, as we have considered with you all possible situations that may arise in the work with the rotary tool and drill when changing drill bits.


With the twist drill it is possible to make a hole in almost any material. This device is most often used when working with concrete, brick and metal, less often with wood.

The variety of materials implies several modes of operation and a large number of nozzles:

The main difference is their purpose.

Drill bits involve drilling piercing work with high-strength materials. In this case, the peorator performs not only drilling, but also impacts or vibrating actions. The drills are used to make accurate holes of the required depth and diameter in surfaces. Drill bits are used for drilling large diameter holes. For example, for a socket. The chisel or spade setting involves operating the tool like a jackhammer.

A significant difference is also the type of attachment, which in all attachments, except for drills, is suitable exclusively for the peorator, because it has a planting tail, attachment in the form of grooves for this tool.

But it is also possible to fit a normal drill bit into the chuck. You need an adapter, which is called a removable chuck. This device comes in two varieties:

The very name of the type defines the type of clamping mechanism of the drill. The cam clamp is actuated by a special wrench, which is inserted into the thread on the outer perimeter and turned. In doing so, the collet mechanism installed inside the chuck is compressed or uncompressed, depending on the direction of the wrench.

The quick-clamping type is actuated by a small effort of the hand. Pressing the chuck in the downward direction opens the drill hole.

Some tips for using the tool

It would not be out of place to remind you how to work with the peorator. This information will be useful for beginner builders.

  • Wear protective equipment: earplugs, gloves, goggles.
  • No force should be exerted on the peorator during work.
  • No idling of the machine.
  • If the material to be cut is very hard, it is necessary to apply lubricant. An alternative to grease can be regular machine oil.
  • If a long drill bit is used, it needs to be drilled with a shorter drill bit.
  • To increase tool life, you should periodically cool the auger in water or oil, and take breaks in your work.

The torch has become a permanent fixture in the life of the builder and installer today. This tool will last a long time if treated properly.

Easy removal of debris with the electrode

If you have a welder and thin electrodes at hand, you can use the welding sticking effect to pull out deeply embedded drill bit fragments.

Welding sticking is a phenomenon of an electrode sticking to metal during welding works. It usually causes a lot of trouble for the welder, but in this case it can be of good service.

The electrodes begin to stick to the metal when their surface has high humidity. Consequently, in order to get the desired effect, it is necessary to wipe the electrode with a slightly damp cloth. But since in this case, it can stick not only to the chip of the drill, but also to the walls of the hole, it is necessary to wrap the electrode with electrical tape almost to the entire depth of the hole. Only the tip itself should remain free.

Once the sticking effect has been achieved, the machine is switched off and the electrode is released from the clamp. Now, by pulling it, it is possible to remove the drill from the workpiece.

This method of removing fragments is one of the easiest, but has a disadvantage. If you do the work sloppily and let the electrode stick to the walls of the hole, you can only make the situation worse.


Used for piercing holes with diameters of 45-80 mm in masonry, concrete and sand-lime brick. Suitable for laying pipelines and cables.

  • drilling head is shaped like a bell and has an asymmetrical arrangement of shanks;
  • the cutting edge is made of tungsten carbide;
  • a large spiral with a long tapered shank ensures efficient operation;
  • the drill bit in the center ensures accurate drilling;
  • the head is designed so that there is less friction in the hole being drilled, which makes it possible to work much faster;
  • designed for through holes.


The peorator is one of the most popular tools today, so it’s hard to underestimate its usefulness. The tool is used by both experienced professionals and ordinary amateurs. In many situations it would be a tight fit without this tool. In this article we look at how to insert the drill bit into the peorator without damaging it. Knowing how to use it properly can help you do your job properly. To insert the drill into the tool, you will need the peorator, drill bit, chuck and lubricant.

What is a peorator?

Before installing a drill in the peorator, first of all, it is worth to understand The present day it is difficult to complete repairs or construction without the help of the peorator. When drilling is required, this tool is simply indispensable. The peorator is used for concrete and brickwork, and is often used for metal or woodwork as a regular drill.

Many functions make this tool versatile. rotation with impact, impact without rotation, rotation without impact, drilling in concrete, jackhammer function, drilling in wood and metal and many others. It’s important to know that there are many kinds of a rotary tool. The principle of the tool is the same, but if you need to drill a wide and deep hole, it is better to use a larger and more powerful device.

What is a peorator tool

To work with this tool, you need different accessories. drills, concrete drills for the peorator, chisels, blades, and crowns. Drills and core bits are used for drilling holes, augers are designed for concrete and stone, chisels are used for chiselling work and spades are necessary for knocking down plaster or old tile. All attachments for the rotary table are shank shaped, which ensures fast and safe fixation in the chuck.

Special angled attachments, dust extraction system, construction or paint stirrers, chisels and various attachments (drill bit sharpening, water pump, sheet metal cutting attachment) can also be used with the rotary tool. Before starting any work with the torch, make sure that it is properly equipped and suitable for the work to be performed. Too small tools may not be able to handle heavy loads.

Protective equipment

Be sure to wear protective equipment when working with the gyroplane. Such equipment includes eyeglasses, ear plugs and gloves. Also should work in special clothing, excluding anything that could accidentally wind itself on the drill bit or drill. When working with the tool, do not put pressure on it, it may end badly.

Avoid running the tool too long at idle. this is allowed only before you check it. When working with porous material use hammerless drilling to avoid crumbling. If you are going to work with hard materials, use cooling lubricant. If you are working with long drill bits, you can start with a shorter twist drill of the same diameter to save energy.

Lubricate the drill shanks every 180 to 200 holes. Watch out for tool heat, if it is too hot, take a break. Alternate periods of rest and work with the tool. As a rule, a break is taken every thirty minutes. Its duration is about ten minutes.

How to insert the drill bit into the peorator: step-by-step instructions

If you follow all the rules and pay attention to detail when working with the rotary tool, the work will be carried out correctly and easily. Always follow construction procedures and don’t forget to check the tool periodically for malfunctions.

Checking for proper operation

Check that the tool is working properly before you change a drill or operate it. Insert the plug into the socket for this purpose and set the drill to drilling mode (leftmost position). Then press the start button. If a smooth, uninterrupted and jerky sound is heard, you are ready to go to work.

Before you start, remember to check the walls or other surfaces for water or electrical wiring. The handle should be firmly fastened and must not drag during work. A check or inspection in good time helps prevent personal injury or damage to the tool.

CAUTION: Never touch the rotating parts of the tool, otherwise it can be extremely dangerous. For the same reason, the drill chuck and drill bit for the bosh peorator should only be installed with the plug unplugged.

Purchasing a chuck

You need to buy a special chuck that fits your model of torch. If you can’t choose or don’t know what chuck is needed it is better to take the tool with you and try the compatibility on the spot.

Today there are two kinds of chucks supplied with the rotary tool, the quick-action one and the key-action one. Key type is a traditional chuck, a wood drill bit is clamped in it with a special wrench. The mount is secure but less convenient than a quick-action chuck. A quick-action chuck can easily clamp the drill bit without the need for any tools. Simply choose the one that is best for you and follow the instructions below.

Choice of drill bits for the geared drill rig

Today drills are made of carbon, high-speed and alloy steels. If stronger materials are to be handled, the drill bit can be equipped with a heavy-duty enduring bit. Drills come in feather, center, straight groove, and spiral (for deep drilling).

You can also buy a drill bit designed for wood, metal, stone, concrete, glass, ceramic, diamond, or a universal version. Before you fix the drill bit in the peorator, you need to decide on the type, if you want the work to be done competently. The color of the drill bit indicates the type of end result.

Some tips for using a drilling tool

In order not to encounter that the flying tool or concrete crumbs will harm your health, the work of drilling must be done with all safety precautions. Protective goggles, gloves, earplugs, or ear muffs should be used as a means of ensuring such safety. You should naturally wear protective clothing for all work and not have any hanging parts that might get caught in the drill bit.

To avoid overheating of the electric tool used for drilling, it is necessary to give it regular rest. It is very important to insert the drill correctly (it must be done until the tool stops).

Two ways of clamping a thin drill bit in a chuck if the jaws do not reach the shank a bit

If the drill bit is stuck in the wall while drilling, it should be extracted without removing the tool from its surface. To do this, take the drill bit out of the chuck and insert another one, with which you must start breaking down the wall around the drill bit that has got stuck in it.

If the drill does not come out of the drill or the torch, you must clamp it in a vise, and then with a hammer, using a wooden pad, tap on the cams of the clamping mechanism. Oil, a few drops of which are poured into the key-type chuck can help in this matter.
