CRL 3" Suction Base Round Drill Guide Ring

• Instantly creates a coolant dam for glass drilling
• Slanted walls help reduce splash and coolant loss
• Cleans easily and resists rust

Use our CRL Suction Base Drilling Rings (SKU: RR30) when drilling glass with coolant or carbide bits. Made from a special rubber compound that cushions glass on contact and minimizes the risk of chipping if dropped. Simple to use: wet the base with coolant or glass cleaner, then press the ring onto the glass to form a secure suction seal. Available in four round sizes plus an oval ring for drilling dual outlets; diameters are measured inside the ring. Ideal for precision glass hole drilling, wet glass drilling, and carbide drill bit applications.

Product Warning:

Always wear proper safety gear including gloves and eye protection when drilling glass. Perform work on a flat, horizontal surface. A Ground Fault Circuit Interrupter (GFCI) must be used when operating electric tools with water or coolant. Failure to follow these precautions can result in operator injury.
