Faster, safer, more effective seam sealant removal. The 3M™ SR Cutter is a plastic rotary cutting tool with an integral metal mandrel, available in diameters of .40 inch and .83 inch. The cutter runs at low speed (850 RPM) on right-angle drills to remove thick polysulfide and polythioether sealants with minimal effect to the underlying paint, primer, alodine or metal. Use together with the 3M™ SR Radial Bristle disc to clean up all remaining sealant.
