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.

Other changes include the spindle which is now specially coated to reduce friction extending the life of the oil seals. The water hose is now very flexible and kink-free. The electrical power cord has an inline GFCI. The Hose lengths are now 15 ft. and are bundled by 3 ft. of an EasyOn-EasyOff sleeve that improves the maneuverability of the polisher. The adjustable splash guard and ventilation cap minimize water getting inside the motor housing. This feature is exclusive to Alpha. The VSP-320 comes with a standard C-Handle for torque-oriented applications such as Profiling and Core Drilling and a standard Side Handle for general edge polishing applications. Lastly， we have eliminated the blow mold case that was difficult to re-pack after you connected all hoses and accessories on the polisher.
