The MILWAUKEE TORCH with NITRUS CARBIDE is the fastest-cutting and longest-lasting blade in cast iron and thick metals.

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 provide easier chip ejection and resist tooth clogs when cutting the thickest metals. Available in 6" 9" and 12" blade lengths in 1PK, 3PK, and 5PK. This blade provides the best performance in all metals 3/16" and thicker.
