1/8" Prismatic Glass Drill Bit

Solid Carbide.

Precision Ground on Three Sides

This CRL Prismatic Glass Drill is the standard of quality for glass drilling throughout the flat glass industry. The tungsten carbide tips mean you can produce hundreds of high quality holes without needing to re-sharpen the drill. The extra long tip assures long lasting, precision drilling.
Prismatic Drills should only be used in glass drilling machines such as the tripod drill, Swivel Drill, or in a securely held electric drill.  Be sure to keep the drill cool using a coolant, or water during drilling.
                           
Product Warning:
These drills should be run at 400-600 RPM to achieve maximum drilling performance. The tip of the CRL Prismatic Drill is not ground to a sharp point. There is a slight angle at the tip to allow the drill to first scratch the glass and begin the drilling of the hole.
