Buttonhead 0.31 Inch Tip 140 Grit Sintered Diamond Point with 3/32 Inch Shank
Sintered diamond points have a 3/32 inch steel shank and a shaped head that has diamond all the way through the head. This gives a longer lasting diamond point with a more consistent grinding finish each time you use it. You must be careful to use these points with water so you don't overheat the point head and destroy the diamond or strip it off the shaft.
