Get professional-grade performance and longer blade life with the Milwaukee® 5-1/4" 14 TPI Bi-Metal Jig Saw Blade - T-Shank (5-Pack). These heavy-duty blades last longer than high-speed steel or carbon blades, combining the strength to cut metal with the durability to withstand impacts without breaking. With Milwaukee’s attention to blade material, tooth shape and sharpness, the jig saw blades produce clean, fast cuts in thick metal, such as metal tubing. The T-shank allows for quick installation.
