The Ax™ blade is designed for the toughest cutting applications in wood and nail-embedded wood. Ax blades have an aggressive pitched shape for superior plunge cutting for demolition and remodeling work. Ax blades are 1 in. tall for straight, fast cuts, and are extra thick, 0.062 in., to prevent bending. Milwaukee SAWZALL blades have a unique heat treatment process that extends blade life, and bi-metal construction prevents the blade from breaking. The 9-inch blade is ideal for cutting through walls containing wood, nails, plaster, and aluminum.
