CRL HBT12 1/2″ HBT Belgian Thread Electro-Formed Diamond Drill

CRL HBT12 1/2″ HBT Belgian Thread Electro-Formed Diamond Drill

C.R. Laurence HBT12 1/2″ HBT Series Belgian Thread Electro-Formed Diamond Drill is engineered for fast cutting and high production runs, making it a top choice for professionals in glass drilling applications. This drill features a 1/2″ (12.7 mm) diamond matrix depth, crafted to deliver exceptional results under precise conditions. Designed with an extended work life in mind, the HBT12 is built for durability and efficiency. The drill is available in two mounting styles: straight shank or Belgian type, with the HBT feature incorporating Belgian mount threads (1/2 – gas), popular for both U.S. and European glass drilling machines. The drill’s shank measures 1-3/8″ by 3/8″ (35 by 9.5 mm), ensuring a positive grip during operation. Due to its fragile nature, this drill is intended solely for use in production-type drilling presses and should never be used for freehand drilling. To enhance cutting capabilities, it is advisable to sharpen or “dress” the drill before each use with a recommended dressing stone. Always prioritize safety by wearing appropriate protective gear, and ensure operations are conducted on flat, horizontal surfaces to prevent accidents. The C.R. Laurence HBT12 is a reliable tool for achieving precision in glass drilling tasks.

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.
