12" 8 TPI TORCH™ with NITRUS™ Carbide SAWZALL® Blade for Cast Iron (5 PK)

The Milwaukee 12" 8 TPI TORCH™ with NITRUS™ Carbide SAWZALL® blades (5 pack) are extended-reach, heavy-duty metal demolition blades designed for the most demanding cast iron and structural steel cutting applications. This is the longest version in the NITRUS cast iron lineup, built for situations where depth, access, and durability all matter at once.

These blades feature Milwaukee’s NITRUS CARBIDE™ tooth technology, engineered for maximum heat resistance and long life in extreme cutting conditions. They are designed to maintain performance when cutting cast iron pipe, stainless steel, black pipe, rebar, and structural steel, even under sustained heavy load.

The 8 TPI (teeth per inch) configuration is optimized for aggressive cutting in thick, hard materials. It provides fast material removal while maintaining stability in dense or brittle materials like cast iron, where excessive blade flex or binding can be an issue.

At 12 inches long, this blade offers maximum reach and cutting depth, making it especially useful for:

• Large diameter pipe removal
• Deep wall or floor cuts
• Hard-to-access mechanical spaces
• Structural demolition where clearance is limited

Milwaukee’s NITRUS carbide technology is designed to deliver significantly longer life compared to standard carbide-tooth blades, helping reduce blade changes during heavy cast iron demolition work.

Key Features:

• NITRUS CARBIDE™ teeth for extreme durability in hard metals
• 8 TPI aggressive design for fast cutting in thick materials
• Specifically engineered for cast iron and heavy steel applications
