I have found it easier, quicker, and more accurate to put that exact same size drill bit in a 3/8" drill, and then lightly dimple the pinblock through the plate holes. The small, conical depression that is left does a real clean job of centering the tuning pin hole when you put the block under the drill press. Regards, Ed Foote
