Our universal fit OPEN-LOK™ three-in-one multi-cutter scraper blade one pack is designed for oscillating multi-tools. The Milwaukee® three-in-one multi-cutter scraper blade is made from solid stainless steel with three different sharpened edges to bring you a three-in-one multi-cutting blade. This blade efficiently cuts through carpets, roofing paper, asphalt roofing shingles and cardboard more efficiently than a standard pull-through blade. You can implement the three different cutting edges to make pull cuts, push cuts and scraping cuts.
