Silicon carbide sanding discs cut fast on stone and are a cheap way to clean up edges, blend repairs and get a honed finish. We stock Starcke SC sandpaper in 4" and 5" discs, sold in boxes of 100, so you're not running out mid-job. Use them on a variable speed polisher after your diamond cup wheels, or for light work between stone polishing pad steps. More everyday consumables are in stone fabrication shop supplies.
