Milwaukee 12-Piece SAWZALL Demo Blade Set

The Milwaukee 12-Piece SAWZALL Demo Blade Set (model 49-22-1129) brings professional-grade demolition blades together in one package. Buying the set typically beats purchasing individual ‘The Ax’, ‘The Torch’, and ‘The Wrecker’ blades — which matters when you’re buying blades by the dozen for crew trucks.

Worth it for contractors who need reliable blades that survive nail impacts. The NAIL GUARD™ technology with its 5 TPI pattern protects against tooth fractures, and the FANG TIP™ bites into wood on first contact for faster plunge cutting. With a 71% - 87% recommendation rate based on store data, these blades deliver what demolition crews need.

Skip it if you’re cutting clean lumber without nails. Standard bi-metal blades cost half as much and work fine for predictable materials. This set shines when you’re tearing through old construction where every stud might hide three generations of nails.

Blade Engineering That Actually Matters

The Matrix II bi-metal teeth provide greater durability, sharpness, and wear resistance — not marketing fluff but measurable performance when you’re billing by the hour. The 0.05-inch thick blade stock and 1-inch tall profile deliver straighter cuts and reduced bending. Thicker blades mean less wandering in the cut, which translates to cleaner demo work and fewer do-overs.

The double relief angle reduces tooth stress for longer blade life, while tough neck ribs reinforce the blade tang and reduce breakage during heavy use. These aren’t features you notice until you don’t have them — when a standard blade snaps at the tang on day three of a bathroom gut.

What You Get and Why It Matters

The kit splits between three blade types, each engineered for specific demolition challenges:

The Ax Blades (5 TPI): You get 2 six-inch and 2 nine-inch blades designed for nail-embedded wood. These are your workhorses for framing demo where every cut might hit metal. The FANG TIP™ design bites into wood on first contact, eliminating that annoying blade-skating when you’re starting plunge cuts in old sheathing.

The Torch Blades (14-18 TPI): The set includes 4 six-inch (18 TPI) and 2 nine-inch (14 TPI) blades for medium to thick metal cutting. Higher tooth count means cleaner cuts through pipe, conduit, and metal studs. The 18 TPI blades handle thinner metals without grabbing.

The Wrecker Blades (7/11 TPI): 2 six-inch multi-material blades for general demolition. Variable pitch reduces vibration when you’re cutting through layered materials — drywall over lath over who-knows-what.

Plus a reusable storage case that holds up to 9-inch blades. Not fancy, but it beats having loose blades rattling around in your tool bag and dulling each other.

Real-World Performance

With an average rating of 4.1 stars, contractors appreciate what these blades deliver. One user noted the case quality and that “the nail-guard wood blades are particularly effective” — exactly what you want to hear for demo work.

Some users noted difficulty with specific thin sheet metals (2mm) leading to tooth deformation. Fair criticism. These aren’t precision metalworking blades — they’re demolition tools optimized for abuse over finesse. For clean metal cuts in thin material, grab dedicated metal-cutting blades.

The universal 1/2 inch tang fits all standard reciprocating saw blade clamps. Basic installation: ensure the saw is unplugged or battery removed, insert the blade tang into the clamp ensuring it clicks or locks, then verify the blade is secure before operation.

Montana Jobsite Reality

Montana construction means dealing with century-old homesteads full of hand-forged nails, modern tract homes with engineered lumber, and everything between. The NAIL GUARD™ 5 TPI pattern protects against tooth fractures when hitting nails — critical when you’re demo’ing old-growth Douglas fir that’s harder than most modern framing lumber and peppered with square nails.

Temperature swings matter too. Cheap blades get brittle when it’s -20°F in a Kalispell January. Matrix II bi-metal construction provides the durability needed for tools that live in unheated job trailers.

The case keeps blades organized and protected from the moisture that turns exposed metal surfaces orange by spring. Small detail that matters when your nearest tool supplier might be 60 miles away.

Frequently Asked Questions

Q: Do these blades fit DeWalt and Makita reciprocating saws?

Yes. The 1/2 inch universal tang works with all standard reciprocating saw blade clamps, including DeWalt, Makita, Bosch, Ryobi, Ridgid, and others. Universal compatibility is standard for recip saw blades.

Q: How thick of metal can The Torch blades cut?

The Torch blades are designed for medium to thick metal cutting. The 14 TPI nine-inch blades handle steel pipe and heavy conduit. The 18 TPI six-inch blades work better on thinner metals and sheet goods. Users report tooth deformation on very thin sheet metal (2mm), so adjust your expectations accordingly.

Q: What’s the warranty on these blades?

Warranty is listed as limited or often shown as “No Warranty” by retailers. CPO offers a 30-day guarantee. Direct warranty typically covers manufacturing defects. Honestly, reciprocating saw blades are consumables — you use them until they’re dull or broken, then grab fresh ones.

Q: Are these worth the premium over standard demolition blades?

With a 71% - 87% recommendation rate, contractors find value in this set compared to purchasing individual specialty blades. If you’re doing occasional demo, buy cheap blades. If you’re billing demolition work weekly, the reduced blade changes and cleaner cuts justify the investment.

Q: How long do these blades typically last?

Blade life depends entirely on what you’re cutting. The NAIL GUARD™ technology, Matrix II bi-metal teeth, and double relief angle all extend blade life compared to standard blades. In nail-embedded lumber, expect 2-3x the cuts of basic bi-metal blades. In clean wood, the advantage shrinks.
