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-in. of walls and under countertops right back to the kick plate. WerkMaster’s 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.
