THE AX SAWZALL blades have been engineered to deliver the fastest cuts, longest life, greatest tooth durability and quickest plunge cuts of any wood demolition blade on the market. THE AX SAWZALL Blade features a NAIL GUARD tooth design to prevent nails from fracturing the blade’s teeth upon impact and an aggressive 5TPI design to deliver fast cuts. While ordinary plunge tooth designs can bounce or skate along the work surface, the FANG TIP design bites into the wood on first contact to make the cut virtually effortless. A pair of unique, fang-like teeth and an extra-large gullet deliver plunge cuts with ease. The combination of these features will allow users to cut through a wide range of standard and abrasive materials without sacrificing the life of their blade.
