How to insert the drill into the drill correctly and how to remove it?

In any living space, sooner or later, a situation arises when something needs to be redone: hang a picture, screw on shelves or make wiring. But most of the concrete and brick walls cannot be pierced with a nail and a screw cannot be screwed into them. Therefore, you have to resort to using an electric drill. This is a convenient device that allows you to make a hole in the wall of the required diameter thanks to the variety of drills: for concrete, metal, glass, plastic, tiles or wood. But for the successful use of an electric drill, you should know the basic rules for using this tool.

Electric drills began to appear at the end of the 19th century almost immediately after the invention of electric motors. The main task of the introduced hammering tool was to drill various holes in materials using electricity and rotating drills at high speed.

Already from the description it is clear: in order to use such a tool, you need to follow certain safety rules.

1. Before starting work, it is imperative to inspect: a drill, so that there are no open electronic (live) parts; the wire going to the network so that it is not damaged; a plug so that it is solid and working; the outlet so that it is functional and fits snugly in the wall. In this case, the plug should fit snugly into the outlet and there should be no sparks.
2. Insert the drill into the drill as tightly as possible.
3. Select the required mode: drilling (twisting the drill at high speed) or drilling (drilling using a percussion mechanism).
4. The maximum speed of the drill is selected.
5. After making a hole of the required diameter and length, press the off button, and then remove the plug from the socket, so as not to accidentally start the tool when not required.

It is worth noting that there are functional drills that recognize the diameter of the drill, have stops for fixing the desired drilling depth, have handles for greater fixation of the tool in the hand, and automatically change the drilling speed. Such functional drills require additional settings so that the automation does not fail at the most inopportune moment.

The drills are selected in accordance with the requirements for the work being carried out. But it must be remembered that they are different, and some drills do not fit a particular drill.

Here the main role is played by the tool holder, which is:

• key;
• quick-clamping.

The first option assumes that the user has a special key that can be used to loosen the cartridge. To do this, you need to use the hole on the drill and turn the key counterclockwise or turn it clockwise, and thus clamp it. Often this key is attached to the drill, which reduces the likelihood of losing it and allows you to remove the key from the mount and use it at any time.

The second option is something different because the quick-release can be:

• single-seat;
• two-clutch.

If you use a single-sleeve chuck, you only need one hand to clamp, and the second option is a little more complicated: you have to clamp one sleeve, and with the other hand, turn the other sleeve. Both options save time, but the retention is much worse than using a key chuck.

This operation is simple and quick, however some rules must be followed. Step-by-step instructions will keep you safe while setting the drill into the drill.

1. Disconnect the instrument from the mains.
2. Then select a suitable drill, taking into account the nature of the work, the material in which the hole will be made and the compatibility of the drill with the drill.
3. Place the drill into the chuck with the shank inward.
4. Then you should fix the cartridge, taking into account its appearance. If it is key, then fix it with a special key with teeth, if it is quick-clamping, then fix it with your hands.
5. Once the drill is secured, make sure that it does not wobble in the chuck and that there is no play.
6. Then you can get to work.

It is worth noting that the choice of drills depends on your electric drill. There are various models with a variety of technical equipment and capabilities. Some drills cannot, for example, be used for metal work. Others - allow the installation of drills with a diameter of 0.8 to 10 mm or 1.5 to 13 mm. It is not recommended to buy cheap drills made of low-quality metal, it is better to overpay, but make sure that the tool works properly and for a long time.

If you need to change a drill that has become unusable, or due to a change in the nature of the work, you need to install another, then the process is even simpler than when setting the drill.

There are also step-by-step instructions for this case.

1. Switch off and disconnect the power drill.
2. Depending on the chuck, use a wrench or turn the sleeve by hand, turning it counterclockwise, thereby loosening the chuck. Avoid touching the drill as it may remain hot for a while after use.
3. After removing the previous drill from the chuck, change it to another and continue working or put the tool away for storage.

If you cannot turn the cartridge the first time, you should not rush to the workshops, most often it is enough just to put in more effort.

In situations where the drill is used only for narrowly focused purposes and from time to time, users tend to send it for repair at the first problems that arise. However, in most cases, it is enough to be able to bypass the non-standard situations that have arisen. To fix minor problems, you need to know how to change the drill, whether it can be done without a key and how to act in the event that it is stuck.

To carry out this procedure, you first need to get the old drill according to the scheme described above, and then put a new one. Electric drills with keyless chucks often have problems due to the fact that the drill is firmly seated and it is not possible to unscrew the coupling. In this case, you can use a piece of cloth that will give more grip on the clutch and try to unscrew it. If this method did not help, then you need to firmly fix the drill with your hand and hit the chuck tangentially in the direction of unwinding with the palm of your other hand, continuing to fix the tool.

Key chucks have a definite advantage - the fixation of the drill is very powerful, but there is also a drawback - it is necessary to have a key at hand. If the key is not in place, it is quite easy to make up for this deficiency. You will need to find an object that can fix the cartridge on one side. This can be a nail, Phillips screwdriver, screw, hexagon of a suitable size. To the second half, you need to make an effort with your hands and try to untwist it - this way it is possible to pull out the drill without a key. But if you can't handle it with your hands, you can use a vice or a large gas wrench of a suitable size.

There are situations when after completion of work it is not possible to remove the drill. Neither unwinding the couplings by hand, if the chuck is keyless, nor the key, if the chuck is key, helps.You tried to turn on the drill and, using the reverse, tried to reach the object, but it did not work. We fixed the drill firmly and tried to loosen the cartridge with tangential blows, but this did not bring the desired result either. So it's time to turn to more massive equipment.

There are not so many ways to remove the drill from the drill:

• Vise and gas wrench. The method involves the use of two gas wrenches or one wrench and a vise. It is necessary to firmly fix one half, and try to shift the other with a key.
• Vise and hammer. One half is fixed in a vice, and the other - with tangential blows of a hammer, moves from a dead center. With the help of the generated vibrations and sharp point effects, it is possible to solve the problem.

If the methods given above did not work, then you can completely unscrew the chuck together with the drill, fix it in a vice and, picking up a screwdriver or some metal rod of the required diameter, knock the drill out of the chuck.
