The Alpha® Twincur™ Final Polish is the only final-polishing buff in the Alpha line offered in three colors instead of the usual two. Composed of tin oxide and natural fibers in heat-compressed form on a snail-lock (SFAT) adapter, it brings granite edges to a super-glossy finish on automatic edge-polishing machines. Three colors let you match the buff to your machine’s water flow — black for dark stones at low water, white for light stones at medium water, and green for high-water-flow machines on any color.

Most final-polish lines offer black for dark stones and white for light stones. Twincur Final Polish adds a green option specifically for automatic machines that deliver high water flow, where black or white can wash out before delivering a full polish.
Black — dark stones on a machine with low water flow. White — light stones on a machine with medium water flow. Green — any color stone on a high-water-flow machine.
It runs after your highest resin grit (commonly #3000) as the final mirror-polish step.
Tin oxide and natural fibers heat-compressed onto a snail-lock (SFAT) adapter body.
It uses a snail-lock (SFAT) backing that fits most popular automatic edge-polishing machines. Add the Alpha PVA-5/8 adapter for 5/8"-11 spindles.
Wet only — continuous water feed is required during polishing.
1,800 RPM.
Granite is the primary application. It can also produce final gloss on similar hard natural stones, but it is not formulated for engineered stone/quartz or sintered surfaces — use the Twincur GEM/GEM-V Tsuya wheel for those.
