Diamond Coated Twist Drills

Designed for drilling hard, brittle materials that standard steel drills cannot handle, Diamond Coated Twist Drills are an essential tool for jewelers and lapidary workers. The diamond abrasive coating delivers efficient cutting performance through gemstones, glass, ceramics, and natural stone, while the spiral flute design promotes chip evacuation and reduces heat buildup during use.

For best results and maximum tool life, use with water or a suitable diamond drilling lubricant. Standard 3/32" shank fits all common flex shaft handpieces, pendant drills, and micromotor systems.
