I popped some years ago for a 16 bit set from Rockler. HSS, and work like a champ. Bought diamond sharpening sticks in several grits, but do occasional touch ups rather than allowing them to get dull. Really nice to have them for the drill press, but I'm not able to hold them steady enough to use freehand. Anyone have any suggestions for some kind of plunge type device to steady the drill in hand held situations?
