Our Best Carbide Drill
Precision Ground on Three Sides
The 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 CRL2, SDM1 and 41, or in a securely held electric
drill. We do not recommend you use them with hand brace drills. Be sure to keep
the drill cool using CRL Pure Gum Turpentine or another coolant like CRL DTC80
These drills should be run at 500-600 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.
Note: The 1/8 inch drill is fragile, and furnished at the purchaser's risk.
