Our Scotch-Brite™ deburr and finish PRO unitized disc is a new disc designed to make a variety of metalworking applications easier and more efficient for industrial professionals. Typically, abrasives excel in one area like deburring, finishing or blending. This multi-purpose disc is unique, because it's engineered to do all three. Scotch-Brite™ deburr and finish PRO unitized disc spans many industries, including oil and gas, aerospace, automotive and metal fabrication. It deburrs, blends and finishes on a variety of workpieces such as threaded pipes and tubular goods, rotors, shrouds, turbine buckets and ducting, gears, sheet metal and engine components, machined and stamped parts. Scotch-Brite™ deburr and finish PRO unitized disc has all the benefits operators have come to expect from our Scotch-Brite™ abrasives, including load resistance and responsive open web. What sets this disc apart from other Scotch-Brite™ abrasives is 3M™ ceramic precision shaped grain (PSG). The proprietary mineral - interwoven throughout the abrasive - is engineered for hardness and strength. It self-sharpens to provide more consistent results. The sharp cutting mineral is counteracted by soft, buoyant nylon fibers that respond to surface irregularities and contours. Gaps between fibers allow debris to escape and help minimize loading. Together, the web and mineral combine to aggressively tackle the substrate without sacrificing predictable results. Unitized discs differ from convolute discs, because they feature a layered construction - the open web is cured and compressed for added strength and durability. The unique production method makes unitized discs a good match for edges and contours. Moreover, the discs may be run clockwise or counter-clockwise. We recommend using this disc with a 3M™ grinder T27 (sold separately). Scotch-Brite™ deburr and finish PRO unitized discs are ideal for maintenance operations. These hard-working, high performance products last through dirt, corrosion and other contaminants without loading and without changing part geometry - helping you get the job done faster.
