About This Product
Resin Polishing Discs for Wet Granite Polishing
Alpha® Ceramica Resin Polishing Discs are high-performance resin discs for wet hand polishing granite. The six-grit system progresses from 150 through 3000 grit to produce a professional polished finish on granite edges and other finished surfaces.
Flexible Polishing for Curved Edges and Sinkholes
Heat-sintered in a mold with a durable resin compound, Ceramica Resin discs are extremely flexible for polishing curved and confined areas. Their flexibility makes them well suited for curved granite edges and tight areas such as inside sinkholes for undermount sinks where a rigid polishing disc can be difficult to control.
3", 4" and 5" Hook & Loop Polishing Discs
Ceramica Resin discs are available in 3", 4", and 5" diameters with a hook-and-loop attachment and a maximum operating speed of 4,000 RPM. Each size is offered in 150, 300, 500, 1000, 2000, and 3000 grit, allowing the same polishing sequence to be used across multiple disc sizes.
