Diamond Jewelry Bits

Ideal for use with the Hi-Tech Diamond® and Dura-BULL® flat-lap machines, this jewelry bit features an edge coated with 100-grit industrial diamond. Use this edge to create perfect channels in materials such as stone, marble, tile and glass to accommodate wire and other findings in creating jewelry pieces. Secure this bit with a set-screw on the side; an Allen wrench is included for this task. Fits onto any 3/8" shaft.
