SR Cutter No.3, 3/8" Dia. x 1" Thick - Pkg Qty 250

The SR Cutter is a plastic rotary cutting tool with an attached 1/4"-28 male threaded metal mandrel for use on slow speed right angle drills. Our SR Cutter works quickly and efficiently to peel off sealants or other thick coatings with minimal to no abrasion to the underlying base material, replacing tedious scraping by hand and messy chemical solvents. A Great Alternative to Tedious Hand Scraping-The 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 Solvents-Not only is the 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 SR Cutter-No. 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. Features: Removes sealants and coatings cleanly with minimal or no abrasion to underlying paints, primers or metalEasy-to-use cutter attaches to a rotary tool to replace time-consuming hand scraping with metal scrapers that gouge the workpieceCleans without chemical solvents, eliminating chemical mess and wasteMetal mandrel fits a right angle power toolNo. 3 cutter is for flat applicationsits 0.4" diameter fits between rivets and into tight spacesNo. 8 cutter is 1" in diameter and has an internal cavity designed to fit directly over rivets or other protrusions for thorough cleaningPrimarily used in the aerospace industry - Pkg Qty 250.
