3M™ cut and grind wheels are engineered to help you get more work done for your dollar. They blast through tough jobs with a fast, smooth cut with less pressure and with less chatter on back gouging and root pass grinding. 3M™ precision shaped grain technology slices through metal with super-sharp, micro-replicated points for a cooler, faster and longer lasting cut than conventional crushed abrasive grain. Plus, these long-lasting wheels need fewer changes, so you can power through the daily grind much faster.
