This 6-inch WRECKER SAWZALL blade uses NITRUS Carbide technology to deliver 2X the life of standard carbide-teeth blades. Its 6 TPI design is engineered for material versatility, cutting through everything from nail-embedded wood to thick metals with a single blade. The Fang Tip geometry provides the fastest plunge cuts in wood, plaster, and drywall, while the NITRUS Carbide edge dissipates heat better than other demolition blades for faster, longer-lasting cuts. It features a 1/2 inch universal tang for compatibility with standard reciprocating saws and is made in the USA.
