Alpha VSP-320 Variable Speed Wet Polisher – 4 in., 120V, 700–2,500 RPM
The Alpha VSP-320 Variable Speed Wet Polisher is a 120V electric wet polisher for polishing stone wet, with a variable 700 to 2,500 RPM range and a 5/8 in.-11 spindle. Alpha specifies a 4 in. (100 mm) polishing disc capacity and a 120V / 7.0A / 800W motor with an inline GFCI.
Several distributors list this tool as a 5 in. machine; Alpha's own published disc capacity is 4 in. (100 mm). Confirm the disc size you need before ordering. If you need a compressed-air tool rather than a corded one, the Alpha AIR-830 and AIR-850 pneumatic wet polishers are the equivalents.
