Granite City Tool has introduced two new wheels, including the Q4 Polishing Drum Wheels and the Alpha 4-inch Surfacer Grinding Cup Wheels.

The Q4 Polishing Drum Wheels present a new concept for polishing sinkholes, as they will wear well for ¾- and 1 ¼-inch-sized materials, the company reports. A rubber center gives it flex to follow the contour. The product measures at 5/8” -11 thread, with center water.

Alpha 4-inch Surfacer Grinding Cup Wheels are designed to quickly smooth out the underside of tabletops. They have a maximum rpm of 14,500 and a 5/8” -11 thread.
