10 Best Sawzall Blades For Cutting Thick Metal in 2026

The 25-blade pack and the demolition body design make this a serious value for anyone facing a steady stream of medium metal cutting jobs. The Perma-Shield Coating and arched tooth design are built to handle the heat and abrasion of prolonged use, which means less swapping and more cutting. This combination of bulk pricing and professional-grade durability specs makes it the most logical core inventory blade for a shop or a contractor tackling pipes, angle iron, or rebar on a regular basis.

This 25-pack of Diablo bi-metal blades is built for professional medium metal cutting, with a design that aims for speed and a long lifespan. Its arched blade shape and hardened cutting edge are intended to reduce heat and last up to five times longer than standard blades, which means fewer blade changes on a big job. The 1-inch demolition body is meant to minimize vibration for straighter cuts, while the Perma-Shield coating helps protect against corrosion and gumming in tough conditions.

Diablo’s Steel Demon blades are the first carbide-tipped option designed for extreme metal cutting, including high-strength alloys, cast iron, and stainless steel. Their ultra-hardened carbide edge can last up to 50 times longer than standard bi-metal blades in those specific applications, which means fewer blade changes on tough jobs. The Perma-SHIELD non-stick coating helps resist heat and corrosion, and the one-inch oversized blade body stabilizes the blade for straighter, more precise cuts with less vibration.

These blades are sold in a three-pack. One research mention from an owner describes using them to cut through truck frames for scrapping.

Milwaukee’s Torch blades are bi-metal and have a reputation for not breaking, even in tough applications where other brands fail. Owners report these blades outlast cheaper alternatives and have not broken one during the same work that broke other brands. This five-pack provides a reliable supply for frequent metal cutting, saving time and frustration from mid-cut failures.

The trade-off is in the pack size and specialization. And if you’re stocking a crew or doing an extended project, the 25-pack from Diablo offers more blades per purchase. But for the pro or serious DIYer who needs a dependable blade for metal and values longevity over sheer quantity, Milwaukee’s Torch delivers consistent, predictable results that keep you cutting.

An 8/10 TPI bi-metal blade built with Turbo-Teeth technology is designed to chew through thick metal aggressively while resisting wear. That combination makes these Bosch blades a solid pick when your priority is cutting speed and blade longevity on heavy-gauge material like structural steel or thick-wall pipe. They start sharp and are built to stay that way, which means less time swapping blades and more time making progress on the job.

The trade-off for that speed and durability is the 6-inch blade length, which can be a limitation if you need to reach into a deep cut or make long strokes in demolition. For those situations, a longer blade like the 9-inch Lenox Demolition might be a better fit. But for straightforward, fast cutting on accessible thick metal, the Bosch RESM6X2 delivers a focused, high-performance package.

A 9-inch bi-metal blade built with a taller, thicker profile is designed to withstand the violent twisting of demolition work without bending or snapping. This makes the Lenox blade a logical choice for pros and serious DIYers who regularly face nail-embedded lumber, thick metal, or fire/rescue scenarios where blade failure isn’t an option. Its aggressive 10 TPI teeth will power through solid stock, but the cut will be rougher than what a finer blade produces.

This blade’s 10 TPI coarse tooth design and demolition focus mean it’s built for aggressive cutting through thick, nail-embedded wood and metal. It trades a finer cut for speed and durability in tough applications, so it’s the choice when powering through obstructions matters more than a clean edge.

A six-piece pack of nine-inch blades with a 14 TPI tooth pattern is built for the kind of sustained cutting you face with steel pipe and rebar. The bi-metal construction is the key here, offering the toughness to handle thick metal without immediately dulling or snapping. According to the product description, the set is suitable for both professional projects and home use. The included storage case means you can grab the whole kit from your truck or shelf without fumbling for loose blades.

You get a solid, no-frills set that focuses on core performance over specialization. The universal shank ensures compatibility, so you can run them in any standard reciprocating saw. Compared to something like the 25-pack from Diablo, this HORUSDY set is a more manageable inventory for someone who isn’t burning through blades daily but still wants quality for demanding metal cuts. It strikes a pragmatic balance between having enough blades to finish a big job and avoiding the clutter and upfront cost of an industrial-sized box.

A five-pack of 6-inch blades provides a ready supply for multi-scene cutting, which saves the time and cost of separate purchases. This 14 TPI design is sharp and accurate for materials like metal pipe and sheet, reducing vibration to improve operating efficiency. The bi-metal construction offers high hardness and toughness with excellent heat and wear resistance, which can extend service life during long-term, high-intensity cutting.

The 6-inch length is suitable for medium-thickness materials, while a 9-inch blade like the Lenox Demolition may reach further into wide beams. The 14 TPI tooth count handles general metal cutting efficiently, whereas an 8/10 TPI option like the Bosch RESM6X2 is designed specifically for thick metal.

A TiAlN-coated carbide tip and industrial-grade tooth construction deliver up to 100 times the lifespan of a standard bi-metal blade. That’s the core appeal here. For pros or serious DIYers regularly tackling stainless steel, rebar, and thick angle iron, this blade is built to endure where others quickly fail. The optimized 8 TPI tooth design and friction-reducing coating also translate to smoother, more controlled cuts in these demanding applications, which means less vibration and more predictable results on the job.

The trade-off is specialization. These blades are engineered for thick metal, so they’re not the versatile, all-purpose pack for the occasional user cutting pipe or wood. If your work is more varied, a bulk pack of bi-metal blades like the Diablo 25-pack will be more practical. But when the material gets tough and you need a blade that won’t quit, the EZARC Obsidian’s carbide endurance justifies its premium category. It’s a purpose-built tool for a specific, punishing job.

The curved arc edge is the key here. It puts more teeth into the cut at once, which spreads the load and lets you zip through metal tubing up to twice as fast as a straight blade. That makes it a serious time-saver for plumbers or HVAC techs running through piles of conduit and pipe. The angled shank isn’t just for a secure fit, it adds a helpful downward push, so the blade bites in aggressively without you fighting the saw.

This blade’s arc edge design engages about 110% more teeth than a straight blade, reducing load per tooth for efficient cuts in metal tubing. That geometry is engineered for a specific range, delivering up to twice the speed and longer life in thin-walled material from 2 to 6 millimeters thick. For cutting thicker, solid metal like bar stock, a more specialized carbide blade such as the EZARC Obsidian would be required.

A tall, thick blade profile provides straight cuts in heavy metal and adds durability for demolition, which helps the blade resist bending and wander during demanding cuts. This bi-metal construction aims for a balance of flexibility and a long-lasting edge. The design is noted for efficient chip removal, with DeWalt claiming up to 50% longer life compared to their prior generation blades. However, some owners report the teeth can strip quickly, even when used slowly with lubricant, questioning their performance in the toughest applications. For relentless cutting where longevity is paramount, some users report getting more mileage from brands like Lenox or Milwaukee.
