The Flex model LCP 1703 VR finishes concrete, granite, or marble. The planetary-gear, belt-driven unit is powered by a 10-amp. Variable speed Flex 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. GFCI protection is built in and 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. 877-331-6103.
