The WerkMaster Model 1400 Europa is powerful enough to grind, polish, edge, and buff any surface, including concrete, terrazzo and all natural stone products. It virtually eliminates edging—you can grind, polish, edge and buff to within 1/8 inch of walls and under countertops right back to the kick plate. WerkMaster's patent-pending Octi-Disc Technology and a variable frequency drive allow running as slow as 750 rpm or as fast as 2000 rpm. Werkmaster. 866-373-9375.
