This hourglass shaped bit is designed to grind lamp pieces that have to fit on an angle. This two-sided bit offers a 9-degree and 18-degree edge for panel lamps. Smooth, mitered edges are important in lamp construction to assure a consistent fit for foiling and soldering.
Silver Pro bits are chrome hardened for performance, strength and durability. Bit fits all Diamond Tech Max grinders.
