These CRL Electro-Formed Diamond Drills are thin-walled drill bits for glass with a 1/2" (12.7 mm) deep multi-layer diamond matrix engineered for high-speed, high-production drilling. Designed for precision glass fabrication, the DCD Series adds an extra-long 1-3/8" x 3/8" (35 x 9.5 mm) diameter shank for a positive grip, while the HBT Series (SKU HBT316) uses Belgian-style mounting threads (1/2" gas thread) commonly used on U.S. and European glass drilling machines.
Because these electro-formed diamond drill bits have very thin walls, they are EXTREMELY FRAGILE and intended for drilling flat (plate) glass only in a true running, production-type drilling press. Never freehand drill—use a precision machine or a stabilization base such as CRL GDB1 or GDB2 Glass Drilling Bases when using a hand-held setup. Always dress (sharpen) the drill with a dressing stone before each use to maintain cutting performance.
Safety & handling: Handle with care and use on flat, horizontal surfaces only. Always wear gloves and eye protection. When using electric tools with water or coolant, use a Ground Fault Circuit Interrupter (GFCI). Failure to follow these precautions can result in operator injury and may void the warranty.
Most shipping weights are approximate. If you need an exact weight to calculate shipping costs, contact CRL Customer Service before ordering. Product images are actual or close representations; colors may vary by monitor.
