6" 8 TPI TORCH™ with NITRUS™ Carbide SAWZALL® Blade for Cast Iron (5 PK)

The Milwaukee 6" 8 TPI TORCH™ with NITRUS™ Carbide SAWZALL® blades (5 pack) are top-tier demolition blades designed specifically for the hardest metal cutting applications, with a strong emphasis on cast iron and heavy structural steel.

Built with Milwaukee’s NITRUS CARBIDE™ tooth technology, these blades are engineered for maximum heat resistance and long service life in extreme cutting conditions. This allows them to outperform standard carbide and bi-metal blades when cutting cast iron pipe, stainless steel, black pipe, rebar, and angle iron, where blade wear is typically rapid.

The 8 TPI (teeth per inch) design is optimized for aggressive, high-force cutting. It removes material quickly while maintaining enough control to stay stable through dense, brittle materials like cast iron. This makes it especially useful in plumbing and demolition work where speed and durability matter more than cut finish quality.

At 6 inches in length, these blades are ideal for tight-access metal demolition, such as cutting pipe in walls, under floors, or in confined mechanical spaces. The shorter length also improves rigidity and reduces blade deflection during heavy cuts.

Milwaukee positions this NITRUS line as their longest-life, fastest-cutting carbide blade system, designed to significantly outlast traditional carbide teeth blades in cast iron applications while maintaining cutting speed under heat and load.
