Great Tool! Cuts clean holes with ease. Very sharp; can get away from you and break the pilot bit. I broke (2) pilot bits almost immediately with a portable drill. Pilot bits are very hard but brittle; they will not bend. I made my own pilot drill out of a standard drill. Overall I'm very happy with the product, but wish the pilot bit was a little softer. I see no problem with the pilot drill when the work is held in a vise on the drill press.
