The MILWAUKEE® Universal Fit OPEN-LOK™ 3-in-1 Multi-Cutter Scraper Blade 1 Pack is designed for Oscillating Multi-Tools. The 3-in-1 Multi-Cutter Scraper Blade is made from solid stainless steel with three different sharpened edges to bring a 3-in-1 multi-cutting blade. This blade efficiently cuts through carpets, roofing paper, asphalt roofing shingles, and cardboard more efficiently than a standard pull-through blade. Use the three different cutting edges to make pull cuts, push cuts, and scraping cuts.
