WerkMaster™ Ultra-Flex Plug ‘N Go System technology combined with the advanced concrete polishing tool design delivers uncompromising results faster and easier than any planetary grinder.

WerkMaster™ diamond abrasives deliver deep, crisp, clear mirror finishes on concrete floors and terrazzo floors. The concrete grinder can not only flatten concrete floors, but it can follow a concrete floor better than any planetary concrete polisher, eliminating the frustration of dealing with deep birdbaths and fishbowls. Up to 3/4 inch deep!

Their concrete grinders can grind and polish around drains like no other.
