Milwaukee SAWZALL Reciprocating Saw Blades: 12-Piece Demo Set

Milwaukee’s 12-piece SAWZALL Demo Blade Set (49-22-1129) combines proprietary tooth designs and bi-metal construction to handle the nail-embedded wood that defines Montana demolition work. The Matrix II bi-metal and Double Relief Angle provide longer life than typical carbon steel or standard bi-metal blades, while the strategic mix of blade types covers everything from old ranch renovations to storm damage repairs.

Worth it for contractors who regularly hit nails. The NAIL GUARD technology’s unique 5 TPI pattern protects against tooth fractures when hitting nails — the bane of demolition work. The thicker and taller profile compared to standard reciprocating blades reduces bending and breakage. Skip it if you’re cutting clean lumber or doing basic homeowner projects. Standard blades cost less and work fine when you’re not dealing with nail-riddled 2x4s.

What Makes These Blades Different

The engineering starts with NAIL GUARD — a 5 TPI pattern with a unique design that protects against tooth fractures. Add the FANG TIP that bites into wood on first contact for faster plunge cutting, MATRIX II Bi-Metal Teeth for greater durability, Double Relief Angle to reduce tooth stress, and Tough Neck ribs that reinforce the blade tang. Each feature solves a specific demolition problem.

The blade stock measures 0.05 inches thick — thicker than standard reciprocating blades. The 1-inch tall profile helps produce straighter, more accurate cuts in demolition materials. That height matters when you’re cutting through old framing where every stud was hand-picked by some long-dead carpenter who knew wood.

The bi-metal construction deserves attention. Matrix II provides greater durability, sharpness, and wear resistance compared to basic carbon steel blades. You’re paying for metallurgy that handles the abuse of hitting unexpected nails, screws, and whatever else lurks in old walls.

The 12-Piece Configuration

The set includes 4 pieces of 6 inch 18 TPI The Torch Metal Cutting Blades, 2 pieces of 6 inch 5 TPI The Ax Wood Cutting Blades, 2 pieces of 6 inch 7/11 TPI The Wrecker Multi-Material Blades, 2 pieces of 9 inch 14 TPI The Torch Metal Cutting Blades, 2 pieces of 9 inch 5 TPI The Ax Wood Cutting Blades, and 1 Reusable Storage Case.

That’s not a random assortment. The Torch blades handle medium to thick metal cutting. The Ax blades tackle nail-embedded wood — the whole reason this set exists. The Wrecker blades cover general purpose demolition when you’re not sure what you’re hitting.

The mix gives you four metal blades at 18 TPI for pipe and conduit, four wood blades at 5 TPI for framing lumber, and four multi-material blades for everything else. The durable plastic case holds up to 9-inch blades, keeping them organized in your truck.

Blade Type	Length	TPI	Quantity	Application
The Torch	6 inch	18	4	Metal cutting
The Ax	6 inch	5	2	Nail-embedded wood
The Wrecker	6 inch	7/11	2	Multi-material
The Torch	9 inch	14	2	Thicker metal
The Ax	9 inch	5	2	Nail-embedded wood

Performance Reality

The Fang Tip technology allows for faster plunging compared to standard straight-back blades. Thicker and taller profile compared to standard reciprocating blades, reducing bending and breakage. Those aren’t marketing fluff — they’re measurable advantages when you’re ripping through old construction.

Set pricing is generally lower than purchasing individual ‘The Ax’, ‘The Torch’, and ‘The Wrecker’ blades. Buy them separately and you’ll spend more for the same blade count. The math works if you need all three blade types.

Reviews average 4.1 stars with 71-87% recommendation rate. Users specifically praise “Great set for general demolition!! Covers all bases for metal and wood” and note the “nail-guard wood blades are particularly effective”. Some users noted difficulty with specific thin sheet metals (2mm) leading to tooth deformation — these aren’t precision metalworking blades.

FAQ

What reciprocating saws work with these blades? Universal 1/2 inch tang compatible with all standard reciprocating saw blade clamps. Works with Milwaukee, DeWalt, Makita, Bosch, Ryobi, Ridgid, and any other brand using universal blade clamps.

How long do these blades last compared to standard blades? Matrix II bi-metal and Double Relief Angle provide longer life than typical carbon steel or standard bi-metal blades. The thicker profile and specialized tooth geometry specifically address the wear patterns of demolition work.

Are these worth it for occasional use? Not really. Set pricing is generally lower than purchasing individual specialty blades, but only if you actually use all three blade types. Weekend warriors should buy individual blades as needed.

What materials can these cut? Applications include nail-embedded wood, medium to thick metal cutting, general purpose demolition, PVC and plastics, and heavy-duty demolition tasks. The varied TPI patterns handle everything from 2x12 headers to cast iron pipe.

What’s the warranty situation? Often listed as ‘No Warranty’ or ‘Limited’ by retailers. CPO offers a 30-day guarantee. Direct warranty typically covers manufacturing defects. Don’t expect warranty coverage for worn teeth — these are consumables.
