CRL 4" Cast Iron Rubber Base Drilling Ring

The CRL Rubber Base Drilling Rings are designed with cast iron rings and secure rubber bases to effectively retain abrasive grain slurry during glass drilling, eliminating the need for a putty dam.
These rings ensure a tight seal, allowing coolant to mix efficiently with the grain for quicker and more efficient drilling.
Available in four different diameters, they can be purchased individually or as a complete set.
Please remember to wear appropriate safety gear, including eye protection, and ensure work is done on a flat, horizontal surface.
Always use a Ground Fault Circuit Interrupter with electric tools when working with water or coolant to prevent injuries.
