CRL HBT14 1/4" HBT Belgian Thread Electro-Formed Diamond Drill

CRL HBT14 1/4" HBT Belgian Thread Electro-Formed Diamond Drill

C.R. Laurence HBT14 1/4" HBT Series Belgian Thread Electro-Formed Diamond Drill is engineered for fast cutting in high production runs, making it an essential tool for professionals in the glass industry. With a 1/2" diamond matrix depth, this drill offers an extended work life, ensuring that you can tackle demanding tasks with efficiency and reliability. The HBT14 features two mounting styles-straight shank or Belgian type-allowing for versatility in your drilling applications. The Belgian mount, with a 1/2" gas thread, is particularly favored for its compatibility with both U.S. and European glass drilling machines. Designed with a thin-walled construction, this drill is optimized for precision work on flat surfaces, making it ideal for drilling plate glass. It is crucial to handle the HBT14 with care due to its fragile nature. Always utilize a precision machine to avoid excessive pressure and enhance cutting capabilities by sharpening the drill before each use with a dressing stone. For added safety, ensure you wear appropriate protective gear and adhere to operational guidelines, such as using a Ground Fault Circuit Interrupter when working with water or coolant. The C.R. Laurence HBT14 combines cutting-edge technology and thoughtful design to elevate your glass drilling experience.

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" by 3/8" (35 by 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.
