Use these CRL Rubber Base Drilling Rings to retain the abrasive grain slurry while the drill is rotating and cutting into the glass. The cast iron rings have rubber bases to hold them securely to the glass, providing a proper seal, and allowing the coolant to mix with the grain for quick, efficient drilling. They are available in four diameters, individually or as a set.
Product Warning:
Always wear the proper safety gear including 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.
