The MILWAUKEE® 3" x .040" x 3/8" Performance+ Metal Cut Off Wheel delivers longer life and faster cuts for metal and stainless-steel cutting applications. Designed for use with a 3" Cut Off Tool, these wheels provide up to 5X life in metal cutting, helping reduce wheel changes during demanding jobs. Advanced aluminum oxide grain maintains sharp edges throughout the cut. It delivers up to 25% faster cutting, while the enhanced bonding structure consistently releases fresh grain as it wears for more control during the cut. Built with 2 full sheets of high-strength fiberglass reinforcement and a higher grain concentration, the wheel is engineered for durability in carbon steel, stainless steel, and nickel-based alloys, including steel, angle iron, pipe, rebar, and other ferrous metals. With a 3" diameter, Type 1 design, 3/8" arbor, this 3-pack is built for repeat use in metal cutting applications.
