The all CRL Corner Radius Cutter takes all of the calculating out of cutting perfectly round corners on glass and mirror. This template is designed to fit over a 90º corner perfectly. The radius cutter automatically centers itself every time you use it so there is no room for error. Adjustable from two separate points; the fulcrum of the cut and the actual radius. Depending on the application, a radius of 20 to 90 mm can be made just by a simple adjustment of the cutting turret. Cutting head has six steel wheels with a 135º hone angle, perfect for general use. Replacement T101 cutting turrets are available.
