The Alpha VSP-320/340 Variable Speed Polisher is a variable speed polisher designed for wet polishing, profiling, and core drilling on granite, marble, quartz, engineered stone, and other hard surface materials. The tool replaces earlier VSP models with an upgraded internal gear system that includes step-down transmission and precision-machined bevel and pinion gears to deliver a controlled speed range from 700 to 2,500 RPM.
The heavy-duty gear design reduces vibration and operating noise while improving service life under continuous use. A specially coated spindle lowers friction and extends oil seal life. The integrated center water-feed system supplies water directly to the polishing surface for cooling and slurry control during wet applications.
VSP-320 models operate on 120V with 5/8"-11 spindle threads, while VSP-340 models operate on 230V with M14-2 spindle threads. Both versions use a single-phase AC power supply and include a 15 ft electrical cord with inline GFCI protection and a 15 ft flexible water hose bundled with an EasyOn-EasyOff sleeve to improve maneuverability.
