Product Details:

Metal Bond Diamonds.

Straight Shank for Use in a Standard Drill Chuck.

This CRL Diamond Countersink features a medium grit diamond for grinding precise, chip-free tapers into existing holes in glass. The 90° angle provides an even 45° chamfer on your holes.

Versatile because the CRL Diamond Countersink can be used on any hole size up to the maximum countersink diameter.

Run at medium speeds, the countersink must be applied to the glass so it touches the circumference evenly.

It can also be used on marble and granite.

Recommended RPM: 2200 – 2600

Additional Product Information:

When this CRL Diamond Countersink gets to be dull, it can be sharpened with a Sharpening Stone to expose fresh diamonds.
