CRL HBT214 HBT Series 2-1/4" Belgian Thread Electro-Formed Diamond Drill

CRL HBT214 HBT Series 2-1/4" Belgian Thread Electro-Formed Diamond Drill

C.R. Laurence HBT214 2-1/4" HBT Series Belgian Thread Electro-Formed Diamond Drill is engineered for fast-cutting and high production runs, making it an essential tool for professionals in the glass industry. With a diamond matrix depth of 1/2" (12.7 mm), this drill boasts an extended work life, ensuring durability and efficiency during demanding tasks. The HBT214 features two versatile mounting styles: a straight shank or Belgian type, allowing for compatibility with various glass drilling machines. The Belgian mount (1/2 - Gas) is particularly favored in both U.S. and European markets. Its thin-walled design provides precision cutting, ideal for drilling flat (plate) glass only, and the extra-long shank (1-3/8" x 3/8") ensures a secure grip during operation. It's crucial to handle this drill with care due to its fragile nature. For optimal performance, always use it in a precision machine, avoiding excessive pressure. Regular sharpening with a dressing stone will enhance its cutting capabilities. Safety precautions, including the use of gloves and eye protection, are essential while operating this tool. The HBT214 is a reliable choice for professionals seeking quality and performance in their glazing applications.

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.
