Machines We Carry
Prep/Master® grinders — our own gear-to-gear concrete grinders and polishers, built to last

Original Flex 2000-watt motor (3 HP) — the power for demanding, continuous stripping
Large bearings for a long life cycle
Fully enclosed mechanical components — prevents adhesive from penetrating the blade assembly and bearings, protecting the machine
Adjustable handgrips to suit any operator height
Padded cushion at the top of the handle — lets you add pressure with your bodyweight for tough material
