Alpha VSP-320 Variable Speed Polisher
The Alpha VSP-320 Variable Speed Polisher is the next-generation upgrade to the popular VSP-120, re-engineered for enhanced durability, precision, and performance. Designed for stone professionals, the VSP-320 features a heavy-duty gear system with a step-down transmission and a bevel-and-pinion configuration, delivering a smooth variable speed range of 700 to 2,500 RPM—perfect for edge polishing, profiling, and core drilling.
Precision-machined components reduce vibration and noise, while the specially coated spindle lowers friction and extends the life of the oil seals. The kink-free, ultra-flexible 15 ft. water hose and inline GFCI-equipped power cord improve safety and usability. An exclusive Alpha® adjustable splash guard and ventilation cap help prevent water from entering the motor housing, ensuring longevity and protection during wet applications. The polisher comes with both a C-Handle for torque-intensive tasks and a Side Handle for general use, offering adaptability for every job. With its EasyOn-EasyOff 3 ft. hose sleeve and simplified storage design, the Alpha VSP-320 combines professional-grade reliability with user-friendly innovation.

Frequently Asked Questions
Can I use the same carbon brush set I purchased for VSP-120 on VSP-320/VSP-340?
No. Unfortunately you need to use the designated carbon brush designed for VSP-320/VSP-340 since they are not the same parts.
Can I use VSP-320/VSP-340 for cutting application?
No. Alpha® doesn’t recommend using a polisher for cutting applications due to the lack of peripheral speed you can get using the max rpm of the polisher.
Is the Limited Warranty the same as before (90 days)?
No. Alpha® warrants this product against defects in material and workmanship for a period of 1 year from the date of original retail purchase.
Can I use VSP-320/VSP-340 for dry polishing application?
No. Alpha® doesn’t recommend VSP-320/340 for dry application although friction between oil seals and spindle was reduced, there is a risk of overheating the oil seal which could deteriorate the sealing capability.
Does Alpha® supply a carriage for scratch removal applications for VSP-320/VSP-340?
No. Since Alpha® improved the application of surface polishing and scratch removal by introducing the Turboshine System with Dual Adapter, which is a much more user-friendly compared with the Twistouch Turbo System, Alpha® has discontinued the polishing carriage
What kind of maintenance do I have to do on VSP-320/VSP-340?
Alpha® recommend the daily discharge of water from the water hose and spindle. We also recommend to blow dry the inside of the motor housing to keep motor dry and blow dust out from moving parts, if compressed air is available.
Where can I send the VSP-320/VSP-340 for repair and maintenance?
You can purchase spare parts from Alpha® if you have a maintenance shop within your company. If you would like to get local service, please take your tool to your local Alpha® dealer or other tool repair shop who offers repair and maintenance services. You may also send it directly to Alpha® for factory repair and maintenance services.
