Belgian Threaded Mount for Sure Fit
Metal Bond Diamonds for Maximum Life

This CRL Diamond Countersink features a medium grit diamond for grinding precise, chip-free tapers into existing holes in glass. Belgian Mounting offers you the best and most accurate way to achieve a fine finish and minimize chipping. The center water feed assures proper cooling when making a deep cut in thick plate glass. This is especially helpful when fabricating glass for use with architectural hardware such as CRL Swivel Fittings or CRL Spider Fitting Hardware. The 90 degree angle provides an even 360 degree chamfer on your drilled holes.

Recommended RPM: 2,200 - 2,600
Diameter:                  1/2 in (12.7 mm)

Minimum Order: 1 Each

Additional Product Information:
It is versatile because the CRL Diamond Countersink can be used on any hole size up to the maximum countersink diameter. Running at medium speeds, the countersink must be applied to the glass so it is centered evenly. It can be used on marble and granite also. Countersinks are available in different angles and diameters on special request.

When your CRL Diamond Countersink is dull, it can be sharpened using a CRL Sharpening Stone to expose fresh diamonds.
