Product Details:

CRL PD Series Metal Bond Diamond Drills use a special diamond and brass bond for maximum performance in glass. Metal bond drills offer the greatest life, 1000 to 2000 holes in 1/4 inch (6.4 millimeter) glass with proper maintenance and the use of a wet Sharpening Stone to expose fresh diamonds, of any type of diamond drill. PD Series Diamond Drills use a special diamond and brass bond for maximum performance in glass drilling. These Italian made multi-layer drills cut faster and run cooler than any other drill on the market. They have a full 3/8 inch (9.5 millimeter) deep cutting surface filled with diamonds and bronze bond, which allows for long drill life, but also makes this style drill more fragile. They should always be used in true running machines on flat glass surfaces. The CRL PD Series Drill can be used in portable drill machines such as the CRL2, but is specially suited for production equipment like a shop drill press. This diamond drill features an extra long 1-3/8 inch (35 millimeters) by 3/8 inch (9.5 millimeter) diameter shank for a positive grip on the drill.
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.
