Used in the intermediate polishing stage, it refines the surface after initial metal grinding steps, effectively removing scratches left by lower grits while beginning to develop clarity and surface smoothness. The heat-resistant phenolic resin bond and semi-flexible construction deliver consistent, efficient scratch removal on planetary and rotary floor grinders.
