The Proxxon Diamond Drilling and Grinding Bit (1.5mm) is a precision micro-bit for drilling and grinding in glass, ceramics, porcelain, and hard stone with Proxxon MICROMOT rotary tools. The diamond coating provides the hardness to penetrate brittle materials cleanlywhere standard HSS or carbide bits would chip or crack the workpiece. At 1.5mm, this bit bridges the gap between the ultra-fine 1.0mm and the larger 3.2mm ball bit, making it ideal for slightly larger precision holes in tile, glass, and stone.
