Just a recommendation from a new user. If you don't have a Drill Doctor yet, get one. It is such a pleasure to have really sharp bits for a change, and knowing that if one is dulled, it literally takes about 15 seconds to have it razor sharp again. I highly recommend Drill Doctor for anyone's shop. I purchased the 750X model which allows the sharpening of larger bits, up to 3/4" as well as the ability to turn chisel point bits into split point bits. Very nice. For your consideration, William R.
