Final Polishing Wheels for Granite Surfaces Alpha® Summit Final Polish Wheels are 10" polishing wheels for finishing flat granite surfaces with radial arm polishers. Used as the final step in the Alpha Summit Polishing System, they produce a high-gloss granite polish with excellent reflection while requiring very little water for lubrication. Heat-Compressed Tin Oxide Polishing Technology Tin oxide is heat-compressed into each wheel to keep the polishing material at the working surface. Unlike loose polishing powder, this construction reduces material waste while supporting fast, consistent polishing and long wheel life. Black and White Wheels for Granite Polishing The Black wheel is recommended for dark granite, while the White wheel is intended for light granite. Alpha also states that the wheels can be used sequentially on black stone for optimal polishing quality. The color-specific options support granite countertop polishing, monument production, and other fabrication work involving flat granite surfaces.
