The Titanium Enhanced Bi-Metal Blade uses premium high-speed steel and lasts up to 15X longer than standard high carbon steel blades. The bi-metal blades have a slightly wider cutting width than most standard bi-metal blades and a longer blade body for a longer reach and deeper plunge cut. A combination of tooth design and material provides better soft metal cutting performance. These bi-metal blades are ideal for smooth cuts in soft metals, wood, nails, copper pipe, PVC, and drywall.
