Proxxon Diamond Twist Drills 0.8mm and 1.2mm (Pack of 2)

Proxxon Diamond Twist Drills in 0.8mm and 1.2mm – a 2-pack of ultra-fine diamond-coated twist drills for precision drilling in glass, ceramics, porcelain, and hard stone with Proxxon MICROMOT rotary tools. The twist drill geometry provides a cleaner, more controlled entry hole than standard diamond bits, reducing the risk of surface chipping on delicate materials like glass and glazed tile.

At 0.8mm and 1.2mm, these are among the finest drill sizes in the Proxxon diamond range – essential for mosaic work, jewelry, stained glass repair, and any application where a clean micro-hole is critical.
