How would I sand down an allen wrench to make it flat on one end?

Question

sand paper? or something else?

Answer 1

use lots of sand!!!

Answer 2

What, flat like a screwdriver? You'd be sanding until doomsday. Use a Dremel or grinder. If you have to, a file will work (and be a bit of work).

Answer 3

A grinding wheel is the best way. Most mechanic shops will have this type of tool. I would have someone familiar with grinding do this for you,,(should only take a few min),,to prevent burning or overheating the end. This would cause brittleness and require more grinding,,good luck..

Answer 4

use a belt sander,  it will work fast, but tool will get hot quickley
