CRL 2-1/2" Cast Iron Rubber Base Drilling Ring

The CRL Rubber Base Drilling Rings are designed to securely retain abrasive grain slurry during glass drilling, thanks to their cast iron rings with rubber bases that ensure a proper seal.
These rings eliminate the need for a putty dam, providing an efficient and quick drilling process as the coolant mixes effectively with the grain.
Available in four different diameters, they can be purchased individually or as a set.
For safe use, always wear appropriate safety gear, including eye protection, and ensure work is conducted on a flat, horizontal surface.
Use a Ground Fault Circuit Interrupter with any electric tool when working with water or coolant to prevent operator injury.
For accurate shipping costs, please contact CRL Customer Service for exact weights if needed, as most shipping weights are approximate.
