Proxxon diamond grinding bits are precision-coated for use with MICROMOT rotary tools — the IBS/A cordless drill/grinder and IBS/E. Designed for grinding, shaping, and drilling in glass, ceramics, hard stone, porcelain tile, and composite materials where conventional abrasives wear too quickly or lack the precision needed. 

The range includes cylindrical grinding bits (5mm diameter, pack of 2) for flat-sided grinding and slotting, spherical grinding bits (4.4mm tip diameter, pack of 2) for curved surfaces and contour work, and diamond drilling and grinding bits in 1.0mm and 1.5mm for precision drilling in glass and tile without cracking or chipping. 

All bits accept standard MICROMOT steel collets. For best results in glass and ceramic: dial down RPM and apply light, steady pressure. For the full Proxxon accessory range see All Proxxon Accessories.
