HAND POLISHING SYSTEM

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)
