The Hardin WP800 4" Variable Speed Wet Polisher is built for precision stone and concrete finishing, trusted by fabricators and installers. Its 800W, 120V motor delivers steady torque across a variable speed range of 1,000–4,000 RPM for smooth transitions from grinding to polishing. The WP800 handles fast stock removal and shaping with diamond grinding wheels, profile wheels, finger bits, and hole saws. A dedicated water feed system with brass valve and reinforced line provides reliable cooling and extends pad life, while a 20 ft GFCI power cord protects against electrical hazards in wet environments. Interchangeable side and top handles give better control on both flat surfaces and vertical edges. With compatibility for 3", 4", and 5" polishing pads, reinforced housing, and a sealed motor, the WP800 is a durable workhorse for shop and field professionals.
