The Milwaukee® 3" 12 TPI Bi-Metal T-Shank Jig Saw Blades (5-Pack) 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 nail-embedded wood. The T-shank allows for quick installation.
