The Milwaukee Reciprocating Ax Blade features a fang tip for fast plunging and a 5 TPI design for accurate, aggressive cuts. Equipped with carbide teeth, the blade is able to cut through materials, such as wood, nails, screws, shingles, plaster, and Rudock, two times faster than standard blades. Additional features include a nail guard, which allows users to rip nails, not teeth.
