The popularity of the question of how to insert a drill into a rotary hammer or an electric drill is explained quite simply: such devices are actively used in both industrial and domestic conditions.
The cartridges are different, as are the nozzles fixed in them
An incorrectly installed drill can lead to a number of problem situations:
- the inability to work with a hammer or drill;
- obtaining uneven holes with a broken inner surface;
- Departure of the drill, which is fraught with serious injuries.
Despite the fact that it is not so difficult to insert a drill into a perforator or a drill, you should approach this issue responsibly.
Correct installation of the drill in the drill chuck
Before you figure out how to properly install the drill in the punch, it is advisable to figure out how to insert the drill into the drill. An element of its design, in which the drill shank is fixed, is a chuck. On most models of modern drills, cam-type cartridges are installed, consisting of:
- cylindrical body;
- rings or sleeves that rotate around the outer surface of the housing;
- cams installed in the inside of the housing.
When the sleeve rotates clockwise, the cams simultaneously approach each other, thereby reliably clamping the shank of the drill being installed. Accordingly, the question of how to remove the drill from the drill is not difficult to solve: it is enough to start turning the sleeve counterclockwise. In this case, the cams will begin to diverge, which will make it easy to remove the drill from the drill. It should be borne in mind that before installing the drill, the cams should be opened with a margin, in which case the tool can be easily inserted.
The convenience of using cam type chucks lies not only in the efficiency and high reliability of the tool installation, but also in the fact that drills of almost any diameter can be inserted into them. When using such cartridges, difficulties with how to change a drill in a drill, as a rule, do not arise. A correctly inserted tool holds these chucks securely and allows you to drill an exact hole.

Cam chucks are used in both industrial and household drilling tools. Clamping devices for household drills are available for two ranges of drill diameters: from 0.8 to 10 and from 1.5 to 13 mm.
The design of cam chucks can include two different methods of clamping a tool: key and quick-clamping.
In the first case, the sleeve is actuated using a special key, on the conical working part of which there are teeth. The key, in order to actuate the clamping mechanism, must be inserted into the holes on the side of the cartridge case and rotated. There may even be three such holes in individual models. Accordingly, in order to loosen or pinch the cams, the key must be inserted into each of them and begin to rotate counterclockwise or along it.
After loosening the cams with the key, it is necessary to turn the cartridge itself counterclockwise, which will increase the distance between the cams to the desired value. The inserted tool is fixed in the reverse order: first the chuck itself is clamped (when it is rotated clockwise), and then the sockets are clamped using the key.

It is much simpler and faster to pull out and install drills when using a quick-clamping chuck. In it, the sleeve is actuated by rotating it manually. To limit the force of the cams, they are often equipped with locking elements.
Before inserting the drill, first make sure that the drill is in working condition and de-energize it. Only then can you start installing the drill.

Installation of a working tool on a rotary hammer
As mentioned above, the hammer must be checked for operability before installing the drill. To perform such a check, the operating mode of the punch is set to drill without a fight. If, after pressing the start button of the device, you hear and feel that its engine is running smoothly and without jolts, it means that the hammer can be used for its intended purpose, after inserting a drill or a drill into it.

Before inserting the drill into the perforator, it is necessary to treat the shank of the working tool with a special lubricant that will protect it from corrosion. The procedure for installing the drill in the punch is as follows.
- The rotary hammer is mounted on the back of the floor or other hard surface.
- The movable part of the clamping device is pulled back.
- The tool is inserted into the punch until it stops. In this case, the drill or drill, which must be inserted into the perforator, must be held vertically. If you neglect this requirement, you may encounter the fact that the tool will fly out or even break, and this can also lead to failure of the puncher itself.
Press down until it clicks, then pull the drill, if it doesn’t come out. everything is fine
Given the fact that clamping chucks on modern rotary hammers are distinguished by a rather simple principle of operation, questions as to how to get a drill out of a rotary hammer, as a rule, do not arise.
After removing the used tool from the punch to replace it with another, it is advisable to immediately clean its shank from grease and building dust. At the same time, the shank of the drill that you are going to insert must also be cleaned and pre-lubricated. Replaced in this way the tool will not harm the clamping mechanism of the punch and will last much longer.
Lubrication extends the life of both the drill itself and the hammer drill
Using a punch, you can not only get a drilled structural element, but also perform processing using a special chisel. You can also install as a working body of such a device mixer.
Home masters often also have questions about how to insert a drill into a screwdriver or how to change a chuck on a hammer drill. To solve the first question is quite simple, since the design of the screwdriver uses cartridges of the same design as on drills and perforators. But the question of how to properly replace the cartridge on a punch, should be approached with skill: it is not easy to carry out such a procedure without certain knowledge and skills.
Some tips for using a drilling tool
In order not to face the fact that a flying tool or concrete chips will harm your health, drilling work must be carried out in compliance with all safety measures. Safety glasses, gloves, earplugs or ear muffs should be used as a means of ensuring this safety. Naturally, all work must be carried out in special clothing, in which there should be no hanging elements that can be wound on the drill.
In order to avoid overheating of the electric tool used for drilling, it is necessary to give it a rest on a regular basis. It is very important to insert the drill correctly (this must be done until the tool stops).
Two ways to clamp a thin drill chuck if the cams do not reach the shank a bit
If the drill stuck in the wall during drilling, it should be removed without removing the tool from its surface. To do this, you need to remove the drill from the punch and insert another, with which you need to begin to destroy the wall around the drill stuck in it.
If the drill cannot be removed from the drill or punch, it must be clamped in a vice, and then with a hammer, using a wooden gasket, tap on the cams of the clamping mechanism. Oil can help in this matter, a few drops of which are poured into a key type cartridge.
