Surely most of those who worked with a screwdriver faced the problem of blunting bits. Now quite often in the market of construction tools there are low-quality goods. Often the metal from which the bits are made is not hard enough and strong enough. And this applies not only to cheap tools. Low-quality fakes are also sold under branded brands. But there is one way to extend the life of removable bits. This is hardening. And that's what this article is about.

Screwdriver bits get dull pretty quickly, especially if you have to use them frequently. And in order to save money, we offer you a way to extend the life of the bit.
Work materials
In order to harden a bat, you will need:
- engine oil (you can even use it);
- gas burner or gas stove;
- metal container for oil;
- a piece of steel wire;
- lighter or matches.
Step 1. Fasten the bat
On the upper part of the bit, which is inserted into the screwdriver, we wind the steel wire so that the bit does not fall out.
As a result, we obtain such a construction.
Step 2. Pour oil into a container
As a metal container for engine oil, you can use a jar of olives or other canned food.
Step 3. Light the fire
We light a fire in a special gas burner or in a gas stove burner.
Step 4. Heat up the bat
Holding the wire with the bat over the fire, heat it red-hot.
Step 5. Dip in oil
We lower the wire with the bat into the engine oil for 5-6 seconds.
Step 6. Summing up
As a result, the bit has darkened, and the metal from which it is made has become more durable. As a result, such a bit will last a little longer than usual.

Hello
Will last a little longer than normal (C)……
How much longer, 2_3 screws? I would like to know more specifically before dancing with a tambourine.
No one will tell you for sure) Here you need to try it yourself. It all depends on your specific tasks and conditions.
If the bit is made of yard steel (and most often it happens with Chinese bits), then there is zero sense in hardening. If the steel is normal, it just hasn't been hardened, maybe something will come out.
Are they never tempered at the factory? Repeated amateur hardening will affect the quality of the bit ...
Alas, not all Chinese bits are tempered
And it also depends on the grade of steel from which the bit is made. You can check the quality of steel by hitting one of the faces of the hexagon bit with a core, if the mark is weak or does not remain at all, then nothing needs to be done with it.
