The MILWAUKEE TORCH with NITRUS CARBIDE is the fastest-cutting, longest-lasting carbide blade in cast iron and other thick metals. Milwaukee NITRUS CARBIDE technology dissipates heat better and provides 5X longer life versus existing carbide tooth reciprocating saw blades, greatly improving user productivity in cast iron cutting applications. This blade features a new 8TPI design, allowing for the fastest and smoothest cuts in all thick metals. With wider gullets than competitive carbide blades, the TORCH with NITRUS CARBIDE will make chip ejection easier and resist tooth clogging when cutting the thickest metals. Available in 6", 9" and 12" blade lengths in 1PK, 3PK and 5PK. This blade provides best-in-class performance in all metals 3/16" and thicker.
