Alpha® introduces the universal concrete surface polishing system for concrete contractors who work on decorative surfaces. This system creates a superior surface polish on concrete whether you are using them wet or dry and by high or low rpms. The WDC Series is available in grits of 60, 150, 300, 500, 1000, 2000 & 3000. Thanks to the patented Alpha® Variable Drive System, you can polish using any polisher, or high-speed angle grinder with the proper dust shroud.
In addition, Alpha® offers a Variable Drive with a Square Adapter that is designed for use on the Ecogrinder. The Ecogrinder allows you to perform the entire process (grinding through polishing) virtually dust-free without the need for an external vacuum. Also, when using the optional Ecocaddy with the Ecogrinder, you can avoid working on your knees! (*discs require a VDSHUB)
