662DR Glass Drilling Bit, 1/8 In. Dia

The Dremel 662DR is a diamond-impregnated core-style drilling bit designed specifically for use with Dremel rotary tools. This specialized bit excels at drilling through glass, ceramic wall tile, glass block, glass bottles, and jewelry with precision and control. Whether you're working on flat or contoured surfaces, this bit delivers the performance needed for detailed, creative projects.

The rasping action created by the full 360-degree diamond grit around the bit's circumference allows you to enlarge holes as needed without switching tools. Side holes built into the bit facilitate dust removal during operation, keeping your work area clean and maintaining visibility of your project.
