CRL HBT2 2" HBT Series Belgian Thread Electro-Formed Diamond Drill

CRL HBT2 2" HBT Series Belgian Thread Electro-Formed Diamond Drill

C.R. Laurence HBT2 2" HBT Series Belgian Thread Electro-Formed Diamond Drill delivers exceptional performance for fast cutting in high production runs. Designed with a 1/2" diamond matrix depth, this drill is engineered to maximize productivity while maintaining an extended work life. The thin-walled construction is complemented by a durable 1-3/8" x 3/8" diameter shank, providing a reliable grip during operation. The HBT2 features Belgian style mounting threads (1/2 - Gas), making it compatible with both U.S. and European glass drilling machines. It's important to use this drill with care, as its fragile design requires precision drilling on flat surfaces only. For optimal results, a dressing stone is recommended to sharpen the drill before each use, enhancing its cutting capabilities. Safety is paramount; always wear appropriate gloves and eye protection when working with glass. The drill should only be used in a true running, production-type drilling press, and never for freehand drilling. Utilizing a hand drill mandates a stabilization base, such as the GDB1 or GDB2. Following these guidelines ensures a safe and efficient drilling experience, making the CRL HBT2 an indispensable tool for professionals in the glass industry.

These CRL Electro-Formed Diamond Drills are thin-walled, with a 1/2" (12.7 mm) deep multi-layer of diamonds and bonding matrix designed for high speed, high production drilling. These drills give outstanding results when exacting conditions are met. The CRL DCD Series features an extra long 1-3/8" x 3/8" (35 x 9.5 mm) diameter shank for a positive grip on the drill. The CRL HBT Series features Belgian style mounting threads, also known as 1/2" (12.7 mm, gas thread), which are popular choices for U.S. and European glass drilling machines.


Due to the fragile nature of these types of drills, they should be used in a precision machine, never allowing too much pressure to be applied. It is important to handle these types of diamond drills with care and use on flat surfaces only. Sharpening or "dressing" of these drills before each use will substantially increase their cutting capabilities. A dressing stone is a recommended necessity when working with an Electro-Formed Diamond Drill.

IMPORTANT NOTE:CRL DCD and 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 perform any type of freehand drilling. The use of a hand drill requieres a stabilization base such as a our GDB1 & GDB2 Glass Drilling Bases. Extreme care and caution should be used as the use of these drill in any other manner other than as specified may damage the bit and void 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.
