Alpha WDP-320 Dry/Wet Variable-Speed Polisher

The Alpha WDP-320 Dry/Wet Variable-Speed Polisher is an updated version of the WDP-120, redesigned for improved durability and dependable wet or dry polishing performance.

Its heavy-duty gear system combines a step-down transmission with bevel and pinion gears to produce a variable-speed range of 700 to 2,500 RPM. Precision-machined components are designed to reduce noise and vibration during operation, while the coated spindle helps reduce friction and extend oil-seal life.

The WDP-320 comes with the Ecoguard G attached for wet or dry tile-edge polishing. It can also be used with water for polishing concrete countertops or connected to a compatible vacuum for dry concrete-floor polishing.
