Bent drill bit


Recommended Posts

If you have a spot of flatness around, e.g. some steel or a granite countertop, then try rolling the bit between the hard surface and a piece of hardwood such as maple.  And even if you don't have a hard surface, then try rolling it between two pieces of maple for a while.  It might likely work for you.

 

You might also reduce the driving pressure when drilling -- let the bit do the work.

Try heating the bit red hot (hold it in pliers), and then stir it in vegetable oil to harden.  Let it cool.  Then bake in oven at ~400F for 30' or so.  

 

You can tell when it's hot 'n ready to dunk in the oil when it is no longer attracted to a magnet, but don't heat the bit beyond that point.
