The Alpha WDP-320 Wet/Dry Variable Speed Polisher is a variable speed polisher engineered for wet polishing and dry polishing of stone, tile, and concrete surfaces. This 120-volt polisher features a heavy-duty gear system with a step-down transmission and bevel and pinion gears that deliver a controlled speed range of 700 to 2,500 RPM.
The tool includes the Ecoguard G attachment to support edge polishing with improved water containment during wet operation or dust control when connected to a vacuum for dry applications. When used with water, it supports polishing of concrete countertops and stone surfaces. When connected to a vacuum, it functions as a dry polisher for concrete floors and tile edges with reduced airborne dust.
Precision-machined internal components are designed to reduce vibration and operating noise. The spindle is coated to reduce friction and extend oil seal life. The unit includes a 15 ft power cord with inline GFCI protection and a 15 ft all-weather water hose designed to remain flexible in varying jobsite conditions.
