The drill is one of the most important tools on the master's table. There is a huge variety of such devices. However, like any other tool on the farm, drills have a tendency to break. Worse, this can happen at the most inopportune moment for this. For example, when the drill is directly in the material. In this case, its extraction can turn into a real "quest". Fortunately, there are proven ways to solve such a problem, and each of them is as simple as fire.
1. Spin counterclockwise
The first thing to try is to grasp the tip of the drill with some more or less suitable tool and try to turn it counterclockwise. This should be done until it starts to rotate freely. Once this happens, the drill can be pulled out by hand.
2. Use welding
It may happen that there is nothing to grab the drill. In this case, it is necessary to start welding and weld an ordinary nut of a suitable size to the stuck tool. After that, the piece is also unscrewed counterclockwise with a wrench or pliers, with which you will need to grab the welded nut.
3. We use a magnet and a core
You can try to turn out the drill with core punches. Beat should be in the space between the cutting edges of the tool. After the drill loosens and starts to move more or less freely, it can be removed using a conventional magnet. Alternatively, a tool capable of delivering a jet of compressed air can be used.

4. We drill
As a last resort, a stuck drill can simply be carefully drilled out with another drill. To do this, use a carbide drill. If the new hole turns out to be too large, then it will have to be filled. It is very important to remember that in no case should the same drill be used for drilling. This will end only with the breakdown of both.

5. Crushing
In the most extreme case, a stuck drill can be tried to crush and then retrieved in fragments. The easiest way to do this is with a sharpened tap. You can also use an ordinary nail. The fragments are pulled out by hand, using a magnet, compressed air, or by simple tapping.
