CRL DCD12 1/2" DCD Series Electro-Formed Diamond Drill, Straight Shank

CRL DCD12 1/2" DCD Series Electro-Formed Diamond Drill, Straight Shank

C.R. Laurence DCD12 1/2" DCD Series Straight Shank Electro-Formed Diamond Drill is engineered for fast cutting and high production runs, making it an essential tool for professionals in the glass industry. This thin-walled drill features a 1/2" (12.7 mm) deep, multi-layer diamond and bonding matrix, optimized for high-speed drilling on flat (plate) glass only. The drill includes a durable 3/8" x 1-3/8" (9.5 x 35 mm) shaft, providing a secure grip for consistent performance. Designed for use in a precision drilling machine, the DCD12 should never be subjected to excessive pressure, ensuring an extended work life. It comes with two mounting styles: a straight shank for standard applications and a Belgian type for compatibility with various U.S. and European machines. Proper handling and sharpening before use are critical to maintaining its cutting capabilities-consider using a dressing stone for optimal results. Please note, due to its fragile design, this drill requires careful use on flat surfaces and should never be operated freehand. Always wear appropriate safety gear, including gloves and eye protection, and utilize a Ground Fault Circuit Interrupter (GFCI) when using electric tools with water. This ensures a safe and effective 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" x 3/8" (35 x 10 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.
