Smart Lapidary Resin Bonded Diamond Bullet Grinder 20mm

A special formulation of resin bonded diamond specifically designed for fast and effective grinding of opals using water as a cooling agent and dust control.

The removal rate of material is very high, allowing the use of finer grits while grinding opal to either expose the colour or smooth out the surface of the opal. Less scratches means less work in the following stages to pre-polish.
