The Ax blade is designed for the toughest cutting applications in wood and nail embedded wood. Ax blades have a sloped shape for superior plunge cutting for demolition and remodeling work. Ax blades are 1 in. tall for straight, fast cutting, and extra thick, 0.062 in., to prevent bending. Milwaukee SAWZALL blades have a unique heat treating process that extends the life of the blades, and bi-metal construction prevents the blade from shattering. The 9 in. blade is ideal for cutting into walls that contain wood, nails, plaster and aluminum.
