Stone Holders are the real workhorses of seat grinding as they have a couple of responsibilities to perform every time they are used. One, of course, is to hold the grinding stone concentrically, and two is to maintain a glove like fit to the OD of the valve guide pilot. Some stone holders like the Kwik-Way unit are rebuildable, meaning you can ...

wheel is really flying even at moderate RPMs. With bore grinding you don't have this option. The diameter of the wheel is limited by the diameter of the bore. Even with a high speed spindle, surface speeds for bore grinding wheels are relatively slow so grinding is much less efficient. So you've got low cutting speed. You've got cantilever.
