These top-quality diamond coated high speed steel twist drills feature a 3/32" (2.35mm) diameter shank — the popular standard in the jewelry industry. The uniform shank size makes it significantly faster and easier to swap drills, particularly when using a fixed collet handpiece such as a quick-change handpiece. Available in 15 sizes ranging from 0.70mm to 2.10mm, these drills are well suited for precision drilling in gemstones, glass, ceramics, and other hard materials. Diamond drills are best used with lubrication.
