CRL PDT78 7/8" PDT Belgian Series Metal Bond Diamond Drill

C.R. Laurence PDT78 7/8" PDT Belgian Series Metal Bond Diamond Drill is expertly designed for high-volume glass fabrication, ensuring exceptional performance and durability. This drill features a robust 3/8" diamond matrix depth, providing a substantial cutting surface that allows for an impressive lifespan of 1,000 to 2,000 holes in 1/4" (6.4 mm) glass, given proper maintenance and the use of a wet sharpening stone. Engineered with a unique diamond and brass bond, the PDT78 operates cooler and cuts faster than traditional drills, making it an essential tool for professionals in the glass industry. Choose between two mounting styles-straight shank or Belgian thread-to fit your equipment needs. The Belgian style mounting threads (1/2" or 12.7 mm gas thread) are widely compatible with both U.S. and European glass drilling machines, while the drill's extra-long 1-3/8" x 3/8" (35 x 10 mm) diameter shank ensures a secure grip during operation. For optimal safety, always wear appropriate protective gear while drilling and ensure the work is performed on a flat, horizontal surface. With the C.R. Laurence PDT78, you can expect reliable performance that meets the demands of your glass fabrication projects.

CRL PD and PDT Series Metal Bond Diamond Drills use a special diamond and brass bond for maximum performance in glass. Metal Bond Drills offer the longest life of any type of diamond drill; 1,000 to 2,000 holes in 1/4" (6.4 mm) glass with proper maintenance and the use of a wet Sharpening Stone to expose fresh diamonds. These Italian made multi-layer drills cut faster and run cooler than any other drill on the market. They have a full 3/8" (10 mm) deep cutting surface filled with diamonds and bronze bond, which allows for extended drill life, but also makes this style of drill more fragile. They should always be used in true running machines on flat glass surfaces. The CRL PD 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 PDT Series features Belgian style mounting threads, also known as 1/2" (12.7 mm) gas thread, which are popular among all U.S. and European glass drilling machines. They can be used in portable drill machines such as the CRL AMZ1, but they are especially suited for production equipment.


NOTE: 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 Interrupt Device (Cat. No. GF1) 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.
