The CRL Electro-Formed Diamond Drill has a thin-wall, with a 1/2" (12.7 mm) deep multi-layer of diamonds and bonding matrix. This drill is designed for high speed, high production drilling and produces outstanding results when exacting conditions are met. Due to the fragile nature of this type of drill, it should be used only in a precision machine, never allowing too much pressure to be applied. It is important to handle the drill with care and use on flat surfaces only. It features habit, tapered style mounting threads which are popular among all British and Australian glass drilling machines.

CRL HBT 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 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.
