10 Best Metal Cutting Sawzall Blades in 2026

With 8% cobalt in its edge, this bi-metal blade resists the heat that dulls ordinary blades, which means it stays sharp through more cuts. The 25-pack suits users who frequently tackle metal projects and want a reliable, all-purpose cutter. Lenox’s Power Blast Technology strengthens the blade body to reduce breaks, and the shatterproof precision-milled teeth maintain their edge. Its T2 Technology allows efficient cutting in a wide range of materials, making it a versatile first choice for mixed-material tasks.

A 6-inch length offers good maneuverability, though deeper cuts may require a longer blade like the 9-inch Diablo Bi-Metal option. Compared to carbide-tipped blades found in smaller packs, like the Diablo Steel Demon, this Lenox set provides a high quantity of blades. The bi-metal construction and included technologies focus on durability and reducing breaks for common metal cutting.

A 25-pack of blades with a specialized arched design and dual tooth configuration means you can power through a lot of medium-gauge metal, like conduit, pipe, or angle iron. These blades are built to cut fast and stay cooler, making them a solid fit for contractors or serious DIYers who burn through blades on jobsites. They need a bulk option that delivers consistent performance without constant changes. The Perma-Shield coating and demolition body are professional-grade touches that aim to reduce gumming and vibration over the long haul.

This 25-pack of Diablo blades is built for high-volume professional cutting of medium metal, with a design focused on speed and reducing downtime. The Full Contact Arched Design aims to cut faster with less heat, while the Perma-Shield coating protects against corrosion and gumming under harsh conditions. Its demolition body is engineered for straighter cuts with less vibration, which provides more control during demanding applications.

The claim of up to 50 times longer life than a standard bi-metal blade when cutting tough metals is the real story here. That’s not marketing fluff, it’s what makes these blades worth their premium spot. They’re built for the jobs that eat other blades for breakfast, like slicing through truck frames, stainless steel, or hardened alloys. The specialized TiCo Hi-Density carbide and the Perma-SHIELD coating are engineered to withstand the heat and abrasion that causes normal blades to fail. This is the set you reach for when the metal is too much for anything else in your kit.

This is a three-pack of specialist blades, not a high-volume set like some 25-count bi-metal packs. The design focuses on cutting power and longevity in extreme materials rather than general-purpose use. Its features, like the hardened carbide and stabilizing body, are built for maximum durability in punishing applications where other blades wear out quickly.

Turbo-Teeth technology allows these blades to last up to three times longer than standard ones, so you can make more cuts in thick metal before needing a replacement. They are engineered for extreme cuts during high-performance applications, with a precision-ground, Swiss-made construction that starts sharp and stays sharper. This design focuses on durability for demanding metal-cutting tasks where frequent blade changes interrupt workflow.

The 8/10 TPI tooth pattern is specified for thick metal, making it less suitable for thin sheet metal where a finer blade like the Bosch RM618 is designed. Compared to other product listings that include packs of 25 blades, this set contains five blades. Its application is for situations where extended blade life in thick material matters more than having a large quantity of blades.

A blade claiming up to 50% longer life changes the math for repetitive metal cutting jobs. This is the blade for a pro or a serious DIYer who spends hours slicing through conduit, pipe, or structural steel and wants to minimize blade changes.

This design focus brings inherent trade-offs. The 5-pack quantity suits dedicated metalwork, while other products like the REEPLAR 25-pack offer a higher count for frequent replacement. The 0.035-inch thickness and spring steel backing aim to strengthen the blade and reduce breaks, but the application list is strictly metal. For materials outside its stated range like wood or thick cast iron, a different blade type would be required.

Designed specifically for sheet metal, this blade’s 18 teeth per inch and zero-degree hook angle deliver clean, controlled cuts without grabbing or tearing thin material. Its flexible 0.035-inch body and pair-setting tooth geometry minimize vibration, helping you follow a precise line on ductwork or auto body panels. You get a blade optimized for 10 to 16 gauge ferrous and non-ferrous sheet, where control matters more than raw cutting speed.

This specialization is the blade’s main trade-off. It is designed for sheet metal within a specific thickness range and is not suited for thicker materials like structural steel or pipe, which require a blade with fewer teeth per inch. For tasks beyond sheet metal, a different blade from your kit would be the appropriate choice.

Owner feedback mentions never breaking a Milwaukee blade, even in applications where other brands failed, which points to reliable durability for daily demolition and general metal work. A 14 TPI bi-metal design handles mixed materials, making this five-pack a straightforward, predictable choice for tradespeople and serious DIYers.

This is a general-purpose blade. For thick steel plate, a blade with a lower tooth count like the 8/10 TPI Bosch RESM6X2 is more appropriate. Thin sheet metal is better suited to a higher TPI option like the 18 TPI Bosch RM618. For a single blade to tackle everything from conduit to angle iron, the Torch provides proven, basic utility.

A blade that lasts up to 100 times longer than a standard bi-metal blade is a serious proposition for anyone who regularly cuts stainless steel, rebar, or angle iron. That longevity, backed by an industrial-grade carbide tip and a friction-reducing TiAlN coating, means you spend less time swapping blades and more time making fast, smooth cuts. This makes the EZARC Obsidian a premium choice for professionals and serious DIYers tackling heavy-duty metal demolition where blade wear is the primary cost and frustration.

This blade’s 8 TPI tooth design and TiAlN-coated carbide tip are engineered specifically for thick metal like stainless steel and rebar, so it’s not intended for wood or thin sheet metal. According to the manufacturer, its industrial carbide tips can last up to 100 times longer than standard bi-metal blades in these demanding applications. For users needing to cut a wider variety of materials, other products like the Bosch RESM6X2 or DeWalt’s 12-piece set offer multiple blades in a pack.

This set’s bi-metal construction and tall, thick blade profile are built for straight cuts in heavy metal and demanding demolition work. The patented tooth design aims for efficient chip removal and longer life compared to older DeWalt blades. It’s a solid choice for the contractor or serious DIYer who needs a versatile set of blades ready for mixed media, like wood with nails or thinner metals. They will appreciate having a dedicated case to keep everything together and protected in the toolbox. The ‘Made in the USA’ blades add a point of pride for many users.

However, owner feedback suggests these blades might not be the ultimate choice for the most brutal, all-day demolition where blade longevity is paramount. When you’re facing nothing but thick, hard metal all week, a specialist blade like the Diablo Steel Demon Carbide or a high-volume pack from Lenox might be a more durable investment. They often come at a higher cost per blade or lack the convenient case.

A 25-pack of blades provides a ready supply for frequent metal cutting, reducing trips to the store. The bi-metal construction with 8% cobalt in the teeth is intended for a longer lifespan during metal removal tasks. This makes the set a logical pick for high-volume, budget-conscious work where running out of blades is a nuisance.

These blades are specified for cutting metal with a thickness from 1/16 inch to 5/16 inch, which includes solid pipes, angle steel, and steel bars. For metals thicker than 5/16 inch, a blade like the Bosch RESM6X2 for thick metal is specified. The manufacturer recommends applying lubricating oil or coolant for the blade to achieve its stated longer lifespan and smoother cutting.
