The 7 Best Reciprocating Saw Blades for Metal of 2026

Eight teeth per inch doesn't sound refined, but that's the point of EZARC's carbide set: the coarse, individually welded teeth are built to hog through cast iron, stainless, rebar, and other thick metal that dulls a bi-metal blade fast. That's why it's our pick for thick metal—not for furniture-grade edges.

The carbide teeth keep biting when a bi-metal blade starts skating, and the 6-inch length gives you enough control to stay on a line without a lot of flex. The 1/2-inch shank fits the standard saws we use, so it's a simple swap. On a rusted bracket or a section of cast pipe, this is the blade we reach for first.

The trade-off is temperament. Carbide is hard, and hard edges chip when they chatter or get forced; keep a steady feed and let the teeth clear the cut. We also don't like an 8 TPI blade for thin sheet or conduit, because it's too coarse and leaves a ragged edge. Buy this for thick metal, and keep a finer blade for the light stuff.

Five 6-inch bi-metal blades with cobalt teeth at a budget price is the appeal here. The 14 TPI tooth count is aimed at 3-10 mm sheet metal and pipes under 100 mm, which covers a lot of the conduit, bracket, and exhaust work that sends people looking for a metal blade.

This is our value pick because it doesn't ask you to baby the blade. The cobalt edge handles heat better than a plain bi-metal tooth, and the 14 TPI pattern clears chips without the ragged finish of an 8 TPI demolition blade. We keep a pack in the shop for cuts where we prefer to replace a blade rather than stop and hunt for one.

The 6-inch length is the main limit: in a deep pipe or a stacked cut, you may run out of reach before the teeth do. For sheet metal, light pipe, and general repair, though, the cost per cut is hard to argue with.

The Milwaukee 12-piece set is the one we grab when the job is a mix of wood, plastic, and metal and we don't want to carry three separate packs. The case is the first thing you notice: it adjusts to hold blades up to 9 inches, and the lid keeps everything sorted instead of loose in a bag.

The blade mix is sensible for demolition. You get four 6-inch 18 TPI blades for metal, two 9-inch 14 TPI blades for heavier cuts, and coarser 5 TPI and 8 TPI blades for wood and nail-embedded lumber. The thicker blade stock is a real advantage in a Sawzall-style saw; it cuts down on the whip you get from thin blades in a deep cut.

This is our multi-material pick because it covers the jobs a household or ranch actually runs into—trimming a gate, cutting a bolt, slicing PVC—without making you buy a dedicated metal pack and a dedicated wood pack. The trade-off is the tooth count: the 18 TPI blades are not the finest option for thin conduit. If metal is the only job, a dedicated pack is a better value. If you want one case that handles the whole repair list, this is the set we reach for.

Twenty-five 9-inch blades in one box is a shop-sized commitment, not a starter pack. The Diablo set is built for auto dismantling and heavy demolition: a 14/18 TPI dual-tooth pattern, a 1-inch demolition body, and a Perma-Shield coating that helps resist heat and gumming when you're cutting through frame rails or rusty steel. That's why it's our pick for auto dismantling and production-style metal work.

We reach for these when a 6-inch blade feels like a toy. The extra length gives you reach through a frame rail or a stacked section, and the arched, thick body runs straighter with less vibration than a thin blade. The dual tooth design is aggressive enough for medium metal without turning every cut into a wrestling match.

This is overkill for a casual user with an occasional bracket to cut. If you need a fine 24 TPI blade for conduit, this isn't it; the pack is all 14/18 TPI. Durability is good but not infinite—these are wear items, and a steady feed still matters more than forcing the saw.

A 24 TPI blade is a specialist, and this five-pack leans into that: it's for clean cuts in thin metal, conduit, and sheet stock where a coarser blade would catch, tear, or leave a ragged edge. That's why it's our pick for clean thin-metal cuts. The 6-inch length keeps the blade stiff, and the bi-metal body gives it enough flex to survive a less-than-perfect line.

We keep this pack for finish work in light gauge. The fine teeth make a smoother cut in copper pipe, aluminum, and thin steel, and the five-pack means you can swap a dull blade without stopping the job. It's also a good fit for a compact saw or a tight space where a 9-inch blade feels unwieldy.

This is a light-gauge specialist, and that's the point. It stays in the drawer for half-inch plate or a rusted frame rail, and it won't replace a demolition blade for wood or nails. For the last clean cut on a conduit run, it's the blade we reach for.

The Makita 6-piece set is a compact assortment for a small reciprocating saw or a tool bag where space is tight. You get one 6 TPI, one 10 TPI, two 18 TPI, and two progressive blades, all 6 inches long, with the first tooth centered for a straight plunge cut.

The 18 TPI blades are the metal cutters in this pack, and they're fine for light pipe, angle iron, and general repair. The progressive blades are a useful compromise when you're not sure what the material will be. It's a sensible little kit for someone who wants a few options without a bulky case.

The 6-inch length is the catch. In a deep cut, the blade can run out of stroke before you're through, and the short length leaves less room to clear chips. On a compact saw, though, that shortness is also what makes the kit controllable; a 9-inch blade can feel like a flagpole on a small tool.

We see this as a compact-saw pick because it doesn't do anything the larger sets don't do better, except fit a small saw and a small budget. If you already own a subcompact reciprocating saw and want a few blades for light metal, it's a tidy choice. If metal is the main event, spend the space on a dedicated pack.
