If you drill fragile materials like sea glass, shells, or glass beads, the right bit makes all the difference. The DRILAX Diamond Drill Bits 30-piece set gives you three popular micro sizes (1mm, 2mm, and 3mm) for jewelry-making tasks like earring holes, bead stringing, and pendant mounting—without the cracking and chipping that can happen with standard bits.

Each bit has a universal 1/8″ round shank designed to work with many rotary systems, including Dremel rotary tools and Foredom flex shafts. The diamond-coated tips are intended for wet drilling to help manage heat and support longer bit life while you work through harder materials such as rocks, mineral specimens, and gemstones.
For best results, use water for cooling, start the hole at an angle, then slowly bring the bit vertical using gentle pressure.
