How to restore a ground screwdriver bit in 1 minute + life hack - hardening bits for a screwdriver (metal is 5 times stronger)
It's a shame to throw away your old, spoiled instrument. Anyone who works with a screwdriver knows that cruciform bits eventually deteriorate.
There is one clever way to restore a damaged, worn-out bat and return it to its previous state. You can then tighten more than one thousand screws with such a bat.
But first, I want to tell you one more trick that will extend the life of the bit in Five times.
Sometimes the metal from which the bits are made is of poor quality, not durable. Even expensive bits can fail.
A way to extend the work of removable bits
Clamp the bat in a vise and start heating it with a burner. You can not heat the whole, but only the upper part. Another option is to wrap the bat with steel wire and then heat it red hot.
Then we dip it into cold water. Some are dipped in machine oil for 4-7 seconds, but it seems to me that there is no sense in this.
As a result, the metal will become many times stronger, and will not grind for a long time.
How easy is it to recover a bit in 1 minute?
This method will save money on buying new bits and time for choosing them, going to the store. Specials are not needed. tools.
All we need is:
- screwdriver,
- file for metal with fine grain.
Don't have a file? Sandpaper or a diamond file will do.
If the bit is heavily worn down, saw off the top (projection) with a file.
Clamp the bit into the screwdriver as usual. Place the screwdriver on a table and turn it on at maximum speed. Place a towel or any rag under the tool.
Then we turn the file at an angle to sharpen the wings of the cross.
Make sure the end does not become sharp. It needs to be made blunt, like on a new bit. If you still get a sharp end, then grind it off by hand using a grindstone.
