Jim The bit I use is cheap as you can get. It only has to be round and have a pointed tip so it puts just the slightest dimple in the Block. As Ron said The bits I drill with I've had for along time as well. I think they came from Pianotech. Small forstner bits will work as well. If they don't fit in the hole grind the outer diameter just enough until they do and the block will have a dimple right in the middle. You can't miss. BTW I always ream out the holes in the plate webbing to make each hole the same size. I don't usually end up taking much out but I am surprised how inconsistent the size of these holes are. On some holes nothing comes out others don't seem to be bored with the same bit. Which, they probably weren't. Dale Yes, that's nice and simple... the brad point bits I've tried to use have trouble clearing the chips..get all jambed up... What does the cutting portion of the tip look like, and who is your supplier...if I may?
