The Flex model LCP 1703 VR fi nishes concrete, granite, or marble. The planetary-gear, belt-driven unit is powered by a 10-amp. variable-speed motor. Its rugged 12-in. platform of Duralumin—a hardened, anodized aluminum—allows for the toughest applications. It is belt driven for quieter operation and less heat buildup. The slurry guard-brush design allows for ease of movement on all surfaces, and the center water feed for wet application can be shut off for efficient dry operation. The unit can use 3- to 5-in. polishing pads. It delivers 1100 to 3400 rpm (the perfect speed) for horning and polishing. Quality diamond design pads in 5 in. x 3 mm and 5 in. x 5.8 mm size are available in 50, 100, 200, 400, 800, 1500, and 3000 grit sizes. Flex North America. 877-331-6103.
