Final Polishing Discs for Granite Edges Alpha® Twincur Final Polish discs complete the polishing process on square and beveled granite edges using compatible automatic edge polishing machines. Used after the progressive abrasive or diamond polishing disc sequence, they produce a super-glossy final finish with Black, White, and Green options for different stone colors and water-flow requirements. 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 use the traditional final polishing method with a low volume of water. Green Final Polish works across granite colors and performs with significantly higher water volume, allowing normal machine water flow when a reduced flow is difficult to control. Heat-Compressed Tin Oxide and Natural Fibers Unlike the diamond polishing wheels used during earlier grit stages, each final polishing disc combines tin oxide and natural fibers in a heat-compressed construction. This composition provides fast, consistent polishing results, long service life, and a highly reflective granite edge finish. 4" Snail Lock Discs for Automatic Edge Polishers Each Twincur Final Polish disc measures 4", uses an SFAT Snail Lock connection, and has a maximum operating speed of 1,800 RPM. The discs fit most popular automatic edge polishing machines, including compatible multiple-head equipment used for production granite fabrication.
