About This Product
Variable Speed Wet Polishers for Stone Fabrication
The Alpha® VSP-320 and VSP-340 Variable Speed Wet Polishers combine an 800W motor, 700–2,500 RPM no-load speed range, and center water-feed system for controlled wet polishing. Both electric polishers accept 4" polishing discs and support edge polishing, profiling, and core drilling applications.
Heavy-Duty Gearing with Reduced Noise and Vibration
A heavy-duty gear system uses a step-down transmission with bevel and pinion gearing to deliver controlled speed across demanding applications. Precision-machined components reduce noise and vibration, while a specially coated spindle reduces friction at the oil seals to support longer tool life.
Center Water Feed and Water Management
A 15 ft. flexible, kink-resistant water hose supplies the center water-feed system through an included garden hose adapter. An adjustable splash guard and ventilation cap help divert water away from the motor housing, while a 3 ft. EasyOn-EasyOff sleeve bundles the hose and power cord for improved maneuverability.
Dual Handles for Polishing, Profiling and Core Drilling
Each wet polisher includes a C-handle for torque-oriented profiling and core drilling and a reversible side handle for general edge polishing. Additional equipment includes a 15 ft. power cord with factory-attached inline GFCI, wrench, extra carbon brush set, splash guard, ventilation cap, and water-hose components.
120V and 230V Electric Polisher Options
The VSP-320 operates on 120V power at 7.0A and uses a 5/8"-11 spindle with a Type A plug. The VSP-340 operates on 230V power at 3.5A and uses an M14-2 spindle with a Type C plug. Both models provide 800W of power, weigh 7.3 lbs., and use single-phase 50/60Hz AC power.

Common Questions
Frequently Asked Questions
What is the speed range of the Alpha VSP-320 and VSP-340?
Both models provide a variable no-load speed range of 700 to 2,500 RPM.
What is the difference between the VSP-320 and VSP-340?
The VSP-320 operates on 120V power at 7.0A and uses a 5/8"-11 spindle with a Type A plug. The VSP-340 operates on 230V power at 3.5A and uses an M14-2 spindle with a Type C plug. Both models provide 800W of power and the same speed range.
What size polishing discs do these wet polishers use?
The VSP-320 and VSP-340 are designed for 4" (100mm) polishing discs.
Do the VSP-320 and VSP-340 have a center water feed?
Yes. Both polishers supply water through the center of the spindle and include a 15 ft. flexible water hose with a garden hose adapter.
Can these polishers be used for profiling, core drilling or cutting?
The polishers support wet polishing, profiling, and core drilling. Alpha does not recommend using them for cutting because their operating speed does not provide the required peripheral blade speed.
Can the VSP-320 or VSP-340 be used for dry polishing?
No. Alpha does not recommend dry operation because excessive heat can damage the oil seals and reduce their sealing capability.
How long are the power cord and water hose?
Both the power cord and flexible water hose are 15 ft. long. A 3 ft. EasyOn-EasyOff sleeve bundles the lines to improve maneuverability.
What equipment is included with each wet polisher?
Each model includes a flexible water hose with garden hose adapter, wrench, C-handle with mounting screws, reversible side handle, extra carbon brush set, ventilation cap, splash guard with clamp, EasyOn-EasyOff sleeve, and factory-attached inline GFCI.
