Diamond Coated 3/32 Shank Twist Drill Kit Of 6 (.90mm To 1.9mm)

These top-quality diamond-coated twist drills feature 3/32" (2.35mm) diameter shanks, making it faster and easier to switch between drill sizes — especially when using a fixed-collet handpiece such as a quick-change handpiece. The 3/32" shank diameter is the popular standard in the professional jewelry industry, ensuring broad compatibility with common rotary tools and handpieces. Diamond drills perform best when used with lubrication to maximize cutting efficiency and extend tool life.

This kit contains six diamond-coated twist drills, one each in six graduated sizes ranging from 0.90mm to 1.9mm, ideal for drilling small, precise holes in stone, glass, ceramic, and hard materials.
