Fit, care, and usage tips

Ensure your grinder is compatible with a 7/8 inch arbor and inspect the blade for wear before use. Store blades in a cool dry place and follow safety guidelines when cutting. For best results, use steady pressure and let the blade do the work to minimize heat buildup. Not recommended for asphalt, tile, or green concrete.
