CRL DCD716 7/16" DCD Series Electro-Formed Diamond Drill, Straight Shank

C.R. Laurence DCD716 7/16" 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. Designed with a thin-walled construction and a robust 1/2" (12.7 mm) deep layer of diamonds and bonding matrix, this drill excels in high-speed drilling applications when exacting conditions are met. The DCD716 features an extra long shank measuring 1-3/8" x 3/8" (35 x 10 mm), ensuring a secure grip during operation. With options for both straight shank and Belgian type mounting, this drill is versatile enough to fit various U.S. and European glass drilling machines. Due to its delicate nature, it is crucial to use the DCD716 in a precision drilling machine, applying minimal pressure to avoid damage. Always work on flat surfaces and consider using a dressing stone before each use to enhance cutting capabilities. Safety is paramount; wear appropriate eye protection and gloves while drilling, and ensure a Ground Fault Circuit Interrupter is utilized when working with water or coolant. The C.R. Laurence DCD716 is specifically designed for drilling flat (plate) glass only, ensuring top performance in every application.

7/16" DCD Series Straight Shank Electro-Formed Diamond Drill

• For Fast Cutting, High Production Runs
• Extended Work Life
• Two Mounting Styles to Choose From Straight Shank or Belgian Type

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.
