3M(TM) SR Cutter No.8, Plastic, 53/64′ Diameter x 1-1/64′ Length, 1/4′-28 Thread, Amber (Pack of 5)
Product Description 3M(TM) plastic rotary cutter on a right angle power tool with its integral metal mandrel at slow speeds to remove sealant and adhesives. Removes coatings without damaging the underlying base material like paints, primers, alodine, and metal. Minimal or no abrasion to paints, primers, or metal on aircraft. Mechanizes procures (vs. hand scraping). No chemicals to apply, clean up, or chemical waste in addition to removed sealant. Less time to do the job. Increases productivity, Easy to use. Color amber. Measures 53/64-inches diameter by 1-1/64 inches length. From the Manufacturer A Great Alternative to Tedious Hand ScrapingThe 3M SR Cutter is designed to save time and increase productivity for cleaning operations typical in the aerospace industry. Two different sizes are available to enable effective coating removalNo. 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 SR Cutter works fast and helps eliminate follow-up work for repainting or repairing damaged coatings.Cleanly Replaces Chemical SolventsNot only is the 3M SR Cutter a great alternative to hand scraping, but it works without the use of messy chemical solvents. It enables operators to remove sealants and residues immediately, without having to wait for chemicals to act or spending time and effort handling and cleaning up a hazardous mess. Your only waste is the sealant itself.Using the 3M SR CutterNo. 3 Cutter: For fillet seals and flat applications, place the No. 3 SR Cutter at head of sealant bead so that the side of cutter contacts the sealant. Apply firm pressure downward onto the sealant and use low rotational speed (throttle down on drill) to remove sealant from one spot without moving the drill back and forth. When the substrate is exposed, increase the rotational speed of the drill and move the tool along the strip of sealant, making sure that the cutter blades adjacent to the substrate rotate into the remaining sealant bead. No. 8 Cutter: For fastener heads, be sure that the inner diameter of the No. 8 SR Cutter will completely fit over the head of the fastener. Place the cutter on top of the fastener with firm pressure. Using the drill throttle, run at low speed to cut away sealant from around the fastener. Remove the sealant by ‘jogging’ the drill in a start-stop fashion several timesthis prevents unwanted frictional heat that may degrade the sealant or blunt the cutter.
