CRL STD4 4" Metal Tube Drill

CRL Metal Tube Drills are designed for use in our CRL Tripod Drill or similar type drill machine. They work with an abrasive grain such as CRL Silicon Carbide Grain to "drill" holes in glass through rotational abrasion. A coolant (or water) is mixed with the abrasive to form a slurry which is retained by a CRL Rubber Base Drilling Ring. The even and steady rotation of the Tube Drill against the glass will produce a clean hole with minimal breakage or chipping. CRL Metal Tube Drills are the economical fulfillment of your glass drilling needs. They have a 1/4" (6.4 mm) diameter shank to fit most drilling machines.
NOTE: Always wear the proper safety gear including eye protection when drilling glass. Work should be performed on a flat, horizontal surface. A Cat. No. GF1 Ground Fault Circuit Interrupt Device 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.
