This round tip drill is broken. The shank tip is not centered on the bit resulting in a hole that is .02" larger than the 11/32. I spent a lot of time sanding the point to try to re-center it. It still drills 0.005 more than the spec says, but that's probably as close as I can hand grind it. Normally my nails are very close to the diameter of the bit. This should not be listed as a recommended product. Very poor quality control.
