BDC12

This CRL Diamond Countersink features a medium grit diamond for grinding precise, chip-free, 90º tapers into existing holes in glass. Versatile because it 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. Countersinks are available in different angles and diameters by special request.
