This IRWIN Bi-Metal Metal-Cutting Reciprocating Saw Blade can cut virtually all metals, including nonferrous pipe conduit, stainless-steel and sheet metals and works well on materials from 1/8-inch to 1/2-inch thick. The bi-metal construction allows for faster cutting and added durability. Precision-set teeth give faster, smoother cuts, while the WeldTec tooth design makes the reciprocating saw blade stronger and longer lasting.
