Well I bought my flex shaft grinder 10 years ago and it cost $400. I guess they really cheapened them up.

You don't accurately alter sleeve timing with a carbide. You ROUGH it out then you accurately finish it with a diamond. You wouldn't use carbide on a boost port or tranfer because there's not enough material removed to warrant a rough cut. I assumed people would have enough common sense on what a rough cut is. After thinking about it your right about the carbide in the hands of a rookie. It is very aggressive and they could screw things up in a hurry. Leave the carbide for the professionals
