[QUOTE="Trickymissfit, post: 710583, member: 25383"] Try it next time with a standard Hi-Roc drill bit. They're made of a softer grade of carbide, and actually drill very accurately. Just crank of the suface speed, and cool it with something like basic grinder coolant (mist works best). A boring bar with a ceramic insert ought to work well too. The hardest ones I've recut were Lee's. They look like they are made of 4350 pretreat and have a very deep nitride case (plasma?) Lee does a very good job in their heat processes, and how they can get them that hard is amazing to me! gary [/QUOTE]
