DEWALT's 14 in. x 1/8 in. x 20 mm Aluminum Oxide Cut-Off Wheel for Metal uses two full sheets of thick fiberglass reinforcement to withstand high-speed operation and demanding cutting conditions. A high grain concentration supports aggressive cutting while helping the wheel run smoothly during use, making it suitable for fabrication, construction, maintenance, and general metalworking tasks. With a maximum rated speed of 5,500 RPM, this single cut-off wheel is designed for metal-cutting applications where consistent performance, durability, and controlled cutting are important.
