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 inch tall for straight, fast cutting, and extra thick, 0.062 inch, 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 12 inch blade is an extra long demolition blade.
