Milwaukee 12" x 24 TPI TORCH Reciprocating Saw Blade 5-Pack

The Milwaukee 12” x 24 TPI TORCH reciprocating saw blade (48-00-5791) delivers what metal-cutting contractors need most — blades that don’t snap at the tang when you’re halfway through a cut. At 12 inches long with 24 teeth per inch, this bi-metal blade handles the thin metal work that fills most commercial and residential jobs: steel studs, copper pipe, ductwork, EMT conduit, and angle iron.

Skip it if you’re cutting wood or thick structural steel. This blade’s 24 TPI configuration is optimized for thin-gauge metals and schedule-10 pipe — it’ll bog down in anything over 1/4” thick. For thicker materials, Milwaukee’s 18 TPI TORCH blade cuts faster, though it leaves a rougher finish.

Blade Construction That Survives Job Site Reality

Milwaukee’s Tough Neck ribs strengthen the blade tang — the part that breaks most often when blades bind or get twisted during cuts. Milwaukee claims it’s the strongest Sawzall tang on the market. That matters when you’re cutting overhead or in tight spaces where blade angle isn’t perfect.

The Grid Iron honeycomb pattern running down the blade body prevents the buckling that ruins straight cuts in sheet metal. This stiffening design keeps the blade tracking true even when you’re pushing hard through corrugated decking or multiple layers of ductwork.

Real-World Metal Cutting Performance

The Double Duty Upgrade tooth design delivers up to 2x longer life compared to previous Milwaukee bi-metal blades. Users report consistent reliability in professional applications like auto-salvage work, with fast cutting speeds for demolition tasks. The 24 TPI configuration leaves a fairly clean edge on tubing and framing — clean enough that you won’t need to deburr every cut for basic fit-up work.

Milwaukee positions this as the stiffest metal-cutting Sawzall blade in the bi-metal category. That stiffness translates to straighter cuts through steel studs and less wandering when you’re trying to follow a layout line on sheet metal.

Universal Compatibility Saves Tool Swapping

The 1/2” universal shank fits every reciprocating saw that matters: Milwaukee SAWZALL and HACKZALL, plus DeWalt, Makita, Bosch, and Ryobi models. No special installation required — the blade drops into any standard blade clamp. This compatibility matters on job sites where crews run different tool brands. One blade type works in everyone’s saw.

Don’t confuse this with Milwaukee’s TORCH Carbide tooth blades — those cost more and target thick or abrasive metals. This bi-metal version handles 90% of typical metal cutting at a fraction of the carbide price.

Frequently Asked Questions

What metals can this blade actually cut? The blade handles steel studs, copper tubing and pipe, galvanized and aluminum ductwork, sheet metal, schedule-10 pipe, corrugated metal decking, EMT conduit, and angle iron. It’s optimized for thin-gauge metals where the 24 TPI can bite effectively.

How does 24 TPI compare to other tooth counts? The 24 TPI provides a finer, cleaner finish on thin metals compared to faster-cutting 18 TPI blades. More teeth means smoother cuts but slower progress. Choose 24 TPI when cut quality matters more than speed.
