These top-quality diamond-coated high-speed steel twist drills are mounted on 3/32" (2.35mm) diameter shanks, making it faster and easier to change from drill to drill—especially when using a fixed collet handpiece such as a quick-change handpiece. The 3/32" shank diameter is the popular standard in the jewelry industry and is compatible with a wide range of flex-shaft and rotary handpieces. Diamond drills perform best when used with lubrication to extend life and improve cutting efficiency.

This assortment includes 15 diamond-coated twist drills ranging from 0.70mm to 2.1mm in 0.1mm increments, providing a complete size progression ideal for stone setting, bead drilling, and precision metalwork.
