Proxxon Diamond Drilling and Grinding Bit 1.0mm

The Proxxon Diamond Drilling and Grinding Bit (1.0mm) is a precision micro-bit for drilling and grinding in the hardest materials – glass, ceramics, porcelain, and hard stone – where standard HSS or carbide bits would chip, crack, or fail. The diamond coating delivers the hardness needed to penetrate brittle materials cleanly, making it the go-to bit for fine detail work in tile repair, mosaic work, jewelry, and lapidary applications.

At 1.0mm diameter, this is one of the finest bits in the Proxxon MICROMOT range – ideal for starting precision holes in glass or ceramic without cracking the surrounding material.
