Instantly Creates a Coolant Dam
Slanted Wall Helps Stop Splashing
Cleans Easily - Won't Rust!
Use this handy CRL Suction Base Ring for drilling glass whenever you use coolant
or carbide grain. Made of a special rubber compound Dual Durometer rubber which
is harder up top to retain its shape, and very soft on the bottom for the
suction lip to create a vacuum. A nice feature of this drill ring is it won't
break the glass if dropped on it accidentally because of the material it is made
from. Easy to use: just wet the base with coolant or glass cleaner and press
onto the glass.
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.
