I have a need to reliably indicate vitrified aluminum oxide (like a surface grinder wheel) and messing with pieces of paper, or shims that rapidly loose thickness, you insert between the indicator tip and the abrasive gets very old very quickly.
So I decided to ask here, what kind of tip is resistant to abrasion by typical vitrified aluminium oxide abrasives? Carbide? Sapphire? Or is diamond the only option? I don't think I ever saw a diamond indicator tip, but diamond brazes well so it should be possible.
