Alpha 4″ Twincur Final Polish

Alpha 4″ Twincur Final Polish

Alpha 4″ Twincur Final Polish is a unique solution within the Alpha Professional Tools® product line, standing out as the only final polish to offer three different options. While most polishing systems provide just two discs—black for dark stones and white for light stones—the Twincur line introduces a third option: the Green Final Polish, specifically designed to perform with a significantly higher volume of water.

This flexibility solves a common challenge fabricators face on automatic edge polishing machines, where water volume is difficult to control. With the Alpha® Twincur Final Polish, users can:

• Use the Black or White discs with minimal water for traditional polishing, or
• Opt for the Green disc to work with standard water flow.

Whichever option is chosen, fabricators can count on achieving a super glossy, professional finish every time. Made of tin oxide and natural fibers in a heat-compressed form, and mounted on a SFAT snail lock adapter, these discs are durable, long-lasting, and efficient.

If you own or plan to own an automatic edge polishing machine, Alpha 4″ Twincur Final Polish is the go-to solution for the ultimate finish.
