Recommended assortment for varied demolition material
49-22-1129: choose it when you need the three different blade roles
Shopping for Milwaukee reciprocating saw blades? The Milwaukee 49-22-1129 12-piece set is a useful starting choice for suitable demolition work involving nail-embedded wood, mixed material and metal. The AX, WRECKER and TORCH groups provide different choices; the benefit is selecting the appropriate one as the job changes.
If most of your work uses only one group, compare the exact individual replacement pack. A larger assortment is not automatically better value when its unused blades stay in storage.
Milwaukee’s manufacturer page identifies the twelve blades and the three families in this set. This guide explains those roles and the selection checks needed before operating a reciprocating saw. It does not turn a broad brand reputation into a claim that every Milwaukee blade is best for every cut.
The exact Amazon US listing had new offers in October 2026. Search results also included third-party “compatible with” products using similar model numbers. Verify the actual brand, package and seller; this guide links the identified Milwaukee set rather than an unnamed imitation. No independent blade-life or cutting-speed test is claimed.
THE AX: nail-embedded wood
Compare this group when the wood can contain nails. Inspect for screws and other embedded objects too, and follow the individual blade’s application. It is not automatically the right blade for thin metal or every mixed cut.
THE WRECKER: general demolition
This group provides a multi-material demolition choice. Identify what is actually in the work rather than treating “general purpose” as approval for an unknown wall or every specialized material.
THE TORCH: metal
Use this group for suitable metal, matched to thickness and blade guidance. The set includes different lengths and tooth counts, so select the specific piece rather than just the family name.

The quantities total twelve blades. Check the actual contents and storage arrangement offered by the seller. Do not use a marketplace package count or a similar search title as proof that a different item contains the same mix.
Is this the right assortment for a renovation?
The set is worth considering when one job includes several appropriate materials. Having wood, multi-material and metal choices available can prevent trying to force the first fitted blade through every subsequent cut. The practical benefit is preparation and a sensible change of blade as the task changes.
It does not replace inspection. Before opening a wall, identify wiring, pipes and structural elements. Before dismantling an assembly, identify fasteners and support loaded parts. A blade able to cut a nail is not permission to cut an unidentified service. Stop when the situation changes and reassess the operation, not just the tooth count.
Thicker demolition profiles still need good support
Milwaukee describes taller and thicker profiles for this demolition assortment. They are intended to improve durability in rough work, but they do not establish that the blade cannot bend, crack or lose teeth. Support the material so it cannot move or pinch the cut.
Do not use the blade as a lever or force it sideways to reach a concealed point. A stronger-looking blade does not correct a poor tool position. Maintain the prescribed shoe contact and hand positions, select a suitable speed, and let the teeth work. This review does not claim measured straightness or blade-life superiority over another set.
Tooth spacing and material thickness belong together
The TORCH pieces in this set have 18- and 14-TPI choices. Select using the individual blade’s material and thickness range. Thin tubing and a thick section present different contact lengths, so a family name alone cannot decide which piece belongs in the cut.
For wood with nails, the AX group serves a different purpose. The WRECKER provides another demolition option, but “multi-material” should not become a rule that one blade cuts every metal and abrasive material. Use the exact blade guidance and tool instructions. If progress is poor, inspect wear, material match and support rather than immediately applying more pressure.
Six inches or nine inches? Check the full movement
Choose enough reach for the blade to stay beyond the work through the full saw stroke. A short blade can catch inside the material; unnecessary length can add flex and reach an obstruction behind the cut. The longest blade in a set is not automatically the most capable choice for every task.
Measure the actual path and inspect behind and beneath the work. Support the retained piece and offcut so the cut cannot close around the blade. A longer blade can address depth where clearance is established; it does not make an obstructed or blind operation acceptable. Reposition the work or choose another suitable tool when access does not allow control.
The marketing names do not replace exact identification
AX, WRECKER and TORCH describe families that can include different blade constructions and applications across Milwaukee’s broader range. This article concerns the specific bi-metal demolition set identified as 49-22-1129. Do not transfer a carbide blade’s advertised capabilities to a similarly named bi-metal piece.
Keep the exact component markings for a successful recurring application. When reordering, compare model, length, tooth pattern, construction and quantity. Search results with a familiar number can include a different brand’s compatible product. Check the actual manufacturer and seller rather than assuming the search title guarantees the same tool.
Set purchase or individual refill?
Buy this mix when you expect to use the different groups. If metal consumes your blades while the AX pieces remain unused, compare a suitable metal refill pack instead of repeatedly buying the complete kit. Count the useful replacements, not just every blade in the package.
Check new condition, delivery, returns and actual contents. Offers in the October 2026 check came from multiple sellers and can change. Avoid publishing a fixed price as though every buyer receives the same deal. The best value is the correct blade available in a useful quantity for the actual task, not the largest package or lowest nominal cost per piece.
Prepare, inspect and store the blade selection
Disconnect the cord or remove the battery before installing or removing blades as the manual requires. Check the clamp and shank, fully seat the blade and verify retention. Secure loose stock independently and begin a cut at an appropriate speed with the prescribed handling.
Let hot blades cool before handling, inspect teeth and backing after work, and separate damaged blades from the usable selection. Protect teeth during storage and keep the markings readable. Replace cracked, badly bent or worn pieces rather than straightening them and assuming full service is restored. Unexpected wear is a reason to reassess the material and setup.
Milwaukee demolition-set questions
Is the case counted as one of the twelve blades?
The manufacturer lists twelve blades in the groups shown above and describes a storage case separately. Check the actual package.
Does TORCH always mean a carbide blade?
No. Identify the exact construction and model. This article concerns the specific bi-metal set.
Can WRECKER cut every material?
Do not infer universal suitability. Follow the individual blade’s material and thickness guidance.
Do I need a Milwaukee saw?
Check the blade shank and clamp requirements in your exact saw manual. The saw’s brand alone is not a complete compatibility decision.
Buy the mix when all three roles earn their place
The 49-22-1129 is a useful Milwaukee demolition assortment when its AX, WRECKER and TORCH choices match the project. Select deliberately from the case and replenish exact individual blades as recurring needs become clear.

Milwaukee’s official component list and exact Amazon US offer were checked in October 2026. This is a researched buying guide rather than an independent blade-life or cutting-speed test.
