Alpha Tools Reconditoned Alpha Variable Speed Wet Polisher - VSP320R

Alpha Tools Reconditoned Alpha Variable Speed Wet Polisher - VSP320R

Alpha has replaced the VSP-120 with the newly designed VSP-320. Although the general appearance of the machines are similar, we have made a major overhaul on these models to make them durable and dependable tools. The major upgrade came in the form of the heavy-duty gear systems that includes the step-down transmission and a bevel and pinion gear to produce the variable speed range of 700 to 2,500 rpm. Thanks to the high-tech machine center, we have all parts precision-machined to reduce noise and vibration during the application. This upgrade ensures a long-lasting tool life and a comfortable application.
