The 3M™ SR Cutter is a plastic rotary cutting tool with an attached 1/4" (6.4 mm)-28 male threaded metal mandrel for use on slow speed right angle drills. The 3M™ SR Cutter works quickly and efficiently to peel off sealants or other thick coatings with minimal abrasion to the underlying base material, and removes the need to scrape by hand or use potentially hazardous chemical solvents.
The 3M™ SR Cutter is offered in two different sizes to enable effective coating removal—No. 3 for flat surfaces and No. 8 for cleaning on and around rivets or other fasteners. The cylindrical blades work both horizontally and vertically against the workpiece to cut through sealants such as polysulfide, polythioether, polyurethane, RTV sealants, and silicones. The plastic blades work effectively without the operator having to pause and resharpen them. The 3M™ SR Cutter works fast and helps eliminate follow-up work for repainting or repairing damaged coatings.
