Flex LW1503 5-Inch Center Water-Feed Single-Speed Polisher

The Flex LW1503 is a compact, single-speed wet polisher designed for edge work and small surface applications on stone, concrete and marble. Its central water-feed system evenly distributes water during wet grinding and polishing to support smooth, uniform finishes.

A 7.4-amp motor delivers heavy-duty performance while the lightweight 4.4-pound design makes the polisher portable and easy to handle. Its constant no-load speed of 3,700 RPM is suitable for polishing sink cutouts, countertop edges, arches, curves and other small surfaces.

The central water-feed nozzle connects to water hoses using quick-action brass couplings for 1/2-inch connectors. Water helps control dust by forming a slurry and supports consistent contact between the polishing pad and the work surface.

The polisher accepts diamond resin polishing pads with hook-and-loop backing. Polishing pads are sold separately.
