How to restore a bat
Very often, cross-shaped bits for a screwdriver, or for a screwdriver with replaceable attachments, fail. Namely, the part of the bit that comes into contact with the screws is typically ground down.
This characteristic wear is familiar to anyone who has ever worked with a Phillips screwdriver for a long time. Over time, a narrowing appears at the tip of the cross, a kind of “piggy”. As a result, the engagement with the screws disappears and the bit becomes unsuitable for work.
I'll show you a simple way to get a worn-out bat back into use. To do this you will need to sharpen it. You won't need any scarce tools.
We will need:
The theory is that we need to grind off the resulting “piggy” with the help of a file.
And then grind down the wings of the cross to the same size. You can use the screw head to control the dimensions.
Now let's move on to practice. To do this, fix the bit in the screwdriver.Set the screwdriver speed to maximum speed.
We press the trigger of the screwdriver and use a file to grind off the spent material sharper. It is better to take a file with fine grain.
Then we place the file at an angle and grind off the wings of the cross. The tip of the crosspiece should not end up being sharp, but a little dull as it was before, since not a single screwdriver is sharpened to a full point.
At the end of sharpening, we check by screwing in the screw.
Instead of a file, you can use sandpaper. To do this, we put it on the table and carry out all the manipulations with the screwdriver itself.
If you don’t have a screwdriver or a drill, then you can do all the manipulations manually or with sandpaper, sharpening each edge separately.
And if you are really lucky and you have an emery cloth and a screwdriver, then you can combine them, then the sharpening time will be completely minimal.

Do-it-yourself bit sharpening
We will need:
- - Cordless screwdriver (if you don’t have it, you can use a drill).
- - Metal file (sandpaper or needle file, preferably diamond).
