About This Product
Final Polishing Discs for Granite Edge Finishing
Alpha® Twincur Final Polish discs are designed as the final polishing step for granite square-edge and beveled-edge applications on automatic edge polishing machines. Available in Black, White, and Green polishing types, the system gives fabricators a choice based on stone color and the water flow used during final polishing.
Black, White and Green Final Polish Options
Black Final Polish is recommended for dark granite, while White Final Polish is recommended for light granite. Both are designed for the traditional final polishing method using a low volume of water. Green Final Polish can be used across granite colors and is designed to perform with significantly higher water volume, allowing operators to use normal water flow when controlling a reduced flow is difficult.
Super Glossy Finish with Fast, Consistent Results
Twincur Final Polish combines tin oxide and natural fibers in a heat-compressed construction to produce a high-gloss final finish with fast, consistent results and long service life. The discs are designed to work on multiple-head machines and fit most popular automatic edge polishing machines.
4" Snail Lock Design for Edge Polishing Machines
Each Twincur Final Polish disc has a 4" diameter, a maximum operating speed of 1,800 RPM, and an SFAT snail lock adapter for installation on compatible edge polishing equipment. The discs are designed for professional granite fabrication where repeatable edge finishing and efficient production are required.
