CRL DCD and HBT Series Electro-Formed Diamond Drills have a thin wall with a 1/2" (12.7 mm) deep multi-layer of diamonds and bonding matrix. These drills are designed for high speed, high production drilling, and produce outstanding results when exacting conditions are met.

CRL DCD Series Diamond Drills have a very thin wall which makes them Extremely Fragile. They are intended for the drilling of flat (plate) glass ONLY, in a true running, production type drilling press. Never use in any type of hand drill. The use of these drills in any manner other than as specified above may damage them and will void any warranty. Always wear the proper safety gear including gloves and eye protection when drilling glass. Work should be performed on a flat, horizontal surface. A Ground Fault Circuit Interrupter must be used when using any type of electric tool in conjunction with water or coolant. Failure to follow any of these precautions can result in operator injury.
