How to restore a bit

Very often, the cross bits for the screwdriver, or for the screwdriver with interchangeable nozzles, fail. Namely, that part of the bit that contacts with screws and screws is characteristic. This characteristic wear is familiar to everyone who has ever worked with a cross screwdriver for a long time. Over time, a narrowing appears on the tip of the cross, such a peculiar "pipochka." As a result, the engagement with the screws disappears and the bit becomes unsuitable for work. I will show you the easy way how to re-launch the batted bit. To do this, you will need to sharpen it. No scarce tools needed.

Sharpening your own bits

We need:
  • - A cordless screwdriver (you can use drill).
  • - Metal file (sandpaper or file, diamond is better).
The theory is that we need to grind off the formed file using a file Pipochka.

Now let's go directly to the practice. To do this, fix the bit in the screwdriver. Set the speed of the screwdriver to maximum speed. Click on the trigger of the screwdriver and use the file to grind off the spent sharper. It is better to take the file with fine grain.

Then we put the file at an angle and grind off the wings of the cross. The tip of the cross should not be sharp at the end, but rather a little blunt as it was before, since not a single screwdriver can be ground under the full edge.

Instead of a file, you can use sandpaper. To do this, put it on the table and have all the manipulations done by the screwdriver. If you do not have a screwdriver or a drill, then you can perform all the manipulations manually or on sandpaper, sharpening each face individually. And if you are completely lucky, and you are the owner of emery and screwdrivers, then you can combine them, then for the time of sharpening it will be quite minimal.
