Scotch-Brite™ Precision Heavy Duty Surface Conditioning Discs are a heavy-duty option designed for durability, long product life, and consistent performance. An extension of 3M's Precision Surface Conditioning Disc family, these discs are ideal for high-pressure applications, such as grinding, deburring, edge breaking, blending, and refining, lasting longer than competitive premium nonwoven abrasives while offering edge durability and shape retention during edge wear; grade XXCRS (60+) lasts 2X longer on mild steel and finishes 3X more mild steel parts compared to competitive premium nonwoven abrasives (based on 3M Internal Testing). The key to this disc's enhanced performance is 3M Precision-Shaped Grain technology, a proprietary molecular bonding technology designed with sharp, angular structures that continuously fracture to form sharp points. Scotch-Brite™ Precision Heavy Duty Surface Conditioning Discs are available in MED (150+), CRS (120+), XCRS (80+), and XXCRS (60+).
