DEWALT 7" x .045" x 5/8-11" Metal Cutting Wheel, 10 pk features Temper Poin™ grains that are engineered to stay razor sharp up to 50% longer than previous DEWALT HP Wheels when cutting carbon steel. The enhanced adhesion between the coated grains and resin results in a longer-lasting cutting edge that wears down slowly, making it highly efficient for various metal cutting tasks. This thin, high-grain concentration wheel is for cutting a wide range of metals, including carbon steel, stainless steel, and nickel-based alloys. Built with two sheets of fiberglass for optimal strength, these wheels are Durable By Design™ to minimize wheel breakage and ensure reliable performance. Model Number: DW8427H
