This bur is for those of you that desire a fine grit and a smaller diameter. This is a 600 grit bur and is for those fine areas and the contours of fire agate carvings.
The softer matrix allows you to shape it as you want and it will give you that fine finish ready for polishing. The rounded tip can be used like a small ball shape for dots or whatever you want. A little gem of a bur.
