Why can't a broken drill be used?

Everyone who has ever held a drill in his hands has had cases when, due to the seemingly slight tilt of the drill, it broke off. As a rule, in such situations only the front third of the drill breaks, and 2/3 of its length remains "targets".

So, it turns out that such a drill cannot be used in any case.

Let me explain why ...

Using a broken drill bit is dangerous for two reasons:

• At first, the top of the drill is the most important in the whole design. Two cutting edges go deeper into the material and guide the entire drill in the desired direction. If there is no edge, then the drill behaves outside the box.
• Secondly, the drill is not a solid tool. It consists of shank and the main part. And these two halves are made from different grades of steel. Accordingly, a broken drill without cutting edges moves incorrectly, and the shank may break off, and part of it may fall into the drill's arm or leg.

This outcome is not needed by anyone, so a broken drill must be removed as soon as it has cooled down a little.

By the way, experienced builders always have 3-4 copies of the most popular drill sizes on hand - in case of breakage.

By the way, in such a clever way you can make sure of the professionalism of the team that you hire for any work.
