I looked all over for one of these that wasnt made of cheap pot metal and had some good reviews. This one had no reviews but I figured one from an aircraft supply company couldnt be BAD, right? I was completely correct. Build quality feels solid, Ive already drilled dozens of holes in very small nuts (also works for bolts, but youll be doing corner holes, same as in the nuts), always coming out clean and straight. one side is 1/16, the other is 5/64. for the purposes Im using (motorcycle bolts) I suggest 0.032 wire, which fits perfectly in 1/16th holes. Make sure youre using a cobalt or better drill bit and go slow with lots of backing out to clear the bit. Overall, for my purposes of moderate/light amounts of bit drilling, this was great. as long as you mount it in a vise, a hand drill will do the job as well, but a drill press will certainly be faster.
