Milwaukee AX Nitrus Carbide Sawzall Blades: A New Standard for Wood Demolition
Wood demolition often feels like a battle against hidden fasteners. One misplaced framing nail can ruin a standard blade, forcing frustrating mid-job swaps. For 2026, Milwaukee Tool is addressing this pain point with the AX with NITRUS Carbide SAWZALL Blade for Wood with Nails & Screws. These blades aren’t just another iteration; they’re engineered to provide up to 2X the life of standard carbide teeth, specifically when tackling nail-embedded materials.
- Extended Life: Delivers up to 2X the life of standard carbide blades in wood-with-nails applications.
- Prompt Plunge Cuts: Features a FANG TIP™ design for the quickest plunge cuts in the market.
- Fastener Protection: NAIL GUARD™ technology ensures the blade rips through nails instead of destroying the teeth.
- Versatile Sizing: Available in 6″, 9″, and 12″ lengths.
The Technology Behind the Nitrus Upgrade
When Milwaukee applies the “Nitrus” designation to an accessory, it signifies their top-tier performance level. The Nitrus Carbide upgrade focuses heavily on tooth geometry and durability to solve the problem of “rounding over” or chipping that occurs when a blade hits a fastener at 3,000+ SPM.
NAIL GUARD™ Technology
Standard carbide blades often struggle when they impact a fastener directly. The NAIL GUARD™ system redesigns the tooth geometry to deflect and cut through fasteners rather than impacting them head-on. This shift in design allows the blade to rip through nails and screws without trashing the teeth by the second row of lumber.
FANG TIP™ Design
Making rough openings or demo access points usually requires pre-drilling or carefully working a blade into the material. The FANG TIP™ at the leading edge is optimized for fast plunge cuts into nail-embedded wood, streamlining the process for pry-start cuts and demolition access.
Ideal Applications and Performance
These blades are purpose-built for residential remodeling and demolition jobs. They are particularly effective when cutting through framing lumber loaded with:
- Embedded nails
- Screws
- Roofing fasteners
The aggressive 5 TPI (teeth per inch) design is balanced to provide fast cuts through dimensional lumber while leaving enough room for the specialized geometry to handle fasteners effectively.
