Top 7 Metal Cutting Sawzall Blades in the Market
The Best Metal Cutting Sawzall Blades, Reviewed
EZARC Carbide 6-Inch 8TPI Blade
Strengths
- Carbide teeth for extreme durability
- 8 TPI aggressive cut
- Handles hardened steel
- 50x longer life
- Universal shank
Trade-offs
- Higher upfront cost
- Less flexible
- Fewer blades per pack
When bi-metal blades start dulling after two cuts in stainless or rebar, that’s when you need carbide. The EZARC R678HM is one of the few carbide-tipped recip blades that actually delivers on its 50x life claim, not in all situations, but in high-alloy steels, cast iron, and hardened beams, owners confirm it outlasts bi-metal by a wide margin. The 8 TPI design with individually welded carbide teeth bites aggressively and handles the heat of continuous cutting.
It’s not cheap, and you only get three, but this is the best overall blade for serious metalwork. It won’t flex like bi-metal, so it’s not ideal for contoured cuts, but for straight, heavy-duty slicing through car frames, I-beams, or machinery mounts, nothing else in this list comes close. If you’re regularly cutting advanced alloys or thick sections, this is the smarter long-term investment.

Bosch RM618 6-Inch 18TPI Blade
Strengths
- 18 TPI for fine cuts
- Thin-kerf body
- Pair-setting teeth
- Straight tracking
- 0° hook angle
Trade-offs
- Struggles with thick metal
- Not for heavy demolition
When the job demands clean, burr-free cuts in ferrous and non-ferrous sheet metal, the Bosch RM618 is hard to beat. The 18 TPI count and 0° hook angle are purpose-built for 10–16 gauge material, and the thin-kerf 0.035-inch body makes starting cuts easier while reducing the chance of binding. Reviewers note these blades track straight and deliver a smoother finish than higher-TPI blades that tend to chatter on thin stock.
The pair-setting tooth geometry, two teeth left, two right, spreads wear evenly and contributes to longer life, which is surprising given how fine the teeth are. And the 3/4-inch blade height helps maintain rigidity. Compared to the EZARC 14TPI, this one sacrifices some durability on thicker metal but wins hands down on precision for ductwork, HVAC, or auto body work. If clean cuts in thin metal matter most, this is my go-to.

EZARC Cryo Tech 6-Inch 14TPI
Strengths
- Cryo Tech treatment
- 8% cobalt content
- 14 TPI for clean cuts
- Longer blade life
- Universal 1/2-inch shank
Trade-offs
- Not ideal for thin sheet metal
- Slightly slower feed rate
The EZARC bi-metal blade stands out in the crowded 14TPI metal-cutting space because of its Cryo Tech heat treatment and 8% cobalt content. On paper, that process should refine the grain structure and slow down fatigue, and owners consistently report noticeably longer life compared to standard bi-metal blades, especially when slicing through medium-thickness steel and pipe. For jobs involving repetitive cuts in 3–8 mm plate or 100 mm pipes, this one holds an edge well and resists heat buildup better than most in its class.
Where it really earns its keep is in sustained use. The 0.9 mm body and set-tooth design do help with chip evacuation, and the 6-inch length with universal shank fits just about any saw. It’s not the fastest cutter in the pack, but if you’re doing more than a handful of cuts, the durability advantage adds up. I’d pick this over a generic bi-metal any day for metal fabrication or maintenance work where downtime for blade changes slows you down.

Diablo 9-Inch 14/18TPI Blade
Strengths
- Perma-Shield coating
- Dual 14/18 TPI
- 9-inch reach
- Demolition-grade body
- 25-pack durability
Trade-offs
- Overkill for light work
- Higher price per blade
Diablo’s DS0914WBF25 is engineered for abuse, the 9-inch length, 1-inch demolition body, and dual 14/18 TPI tooth design make it a favorite in auto salvage and rescue. The Perma-Shield coating shows real-world benefits: owners report less gumming when cutting painted or treated metals, and the blades resist corrosion even in damp toolboxes. The arched full-contact design improves stability, reducing wobble during long cuts.
What sets it apart is how it balances speed and life. The small gullets clear chips aggressively, and the reinforced body cuts straighter than most 9-inch blades. Compared to the 25-pack generic version, Diablo uses tighter quality control and better heat treatment. If you’re dismantling vehicles or doing heavy demolition, this is the blade I’d trust more, it’s built for pros who can’t afford mid-job failures.

25 Pack 9-Inch 14/18TPI Blade
Strengths
- 25-pack value
- 9-inch reach
- 14/18 TPI versatility
- 8% cobalt
- Universal fit
Trade-offs
- Thicker body increases vibration
- Coating overstated
- Inconsistent sharpening
This 25-pack trades some refinement for sheer volume and reach, the 9-inch length is a big plus when you’re deep in an engine bay or cutting through frame rails. The 14/18 TPI dual-grind design suggests versatility, and owners confirm it handles both thicker and thinner metals reasonably well, especially in auto dismantling or rescue work. The 8% cobalt content and bi-metal construction help with durability, though the non-stick coating seems more marketing than miracle.
At this quantity, it’s clearly positioned as a value-driven workhorse pack. But the 0.04-inch thickness makes them stiffer than premium blades, which can increase vibration. They’re not as refined as Diablo or Bosch, but for users burning through blades during demolition or emergency extrication, the trade-off makes sense. I’d recommend this for shops or crews that need bulk blades for mixed metal tasks, not for precision work.

DEWALT 6-Inch 24TPI Blade
Strengths
- 24 TPI for ultra-fine cuts
- Flexible body
- Made in USA
- Bi-metal durability
- Clean finish
Trade-offs
- Too fine for thick metal
- Limited to thin materials
The DEWALT DW4813 is built for one thing: slicing through thin metal with speed and control. The 24 TPI count is unusually high for a recip blade, and combined with a flexible body, it delivers clean, vibration-free cuts in sheet metal, conduit, and thin-walled tubing. Made in the USA with global materials, it has the build quality you’d expect from DEWALT’s legacy line.
Owners report these blades stay sharp longer than cheaper 24 TPI alternatives and resist breaking even when cutting at awkward angles. Compared to the Bosch RM618, it’s similar in application but feels slightly more rigid. If you’re cutting HVAC ducts, electrical boxes, or automotive trim, this blade minimizes burrs and tear-out. Not for heavy stuff, but for thin metal, it’s one of the most reliable options out there.

FRITZFURT 9PCS 6″-12″ Blade Set
Strengths
- Three lengths included
- 14TPI consistent across set
- Durable bi-metal alloy
- Heat treated
- Includes storage case
Trade-offs
- No fine-cut option
- Blades not cobalt-enhanced
Having multiple lengths in one kit is a standout for contractors who move between tight spaces and open cuts. The FRITZFURT set gives you 6-inch, 9-inch, and 12-inch 14TPI bi-metal blades, all with the same tooth pattern, so you’re not constantly adjusting your technique. The 14TPI design handles up to 0.5-inch steel, and owners say they hold up well on rusted pipes and cast iron.
The real win here is versatility and organization. The included storage box keeps blades sorted and portable, which I appreciate after years of digging through junk drawers. Heat-treated bi-metal construction delivers solid life, though not quite at EZARC’s Cryo Tech level. Compared to single-length packs, this is the smarter buy for generalists, homeowners, handymen, or pros who need reach and redundancy without buying three separate packs.

How We Chose These metal cutting sawzall blades
Rather than a hands-on lab test, this selection is a research-led comparison of published specifications, owner reviews, and expert opinions. I focused on identifying blades that consistently receive positive feedback for performance and durability in metal cutting applications. We considered a wide range of blades, evaluating features like tooth count (TPI), blade material, heat treatment, and shank type, and then ranked them based on how well they addressed common metal cutting needs.
For metal cutting sawzall blades, tooth count and blade material are paramount. Higher TPI blades (18-24) excel at finer cuts in thinner materials, while lower TPI (6-14) are better for thicker stock. Bi-metal construction, and increasingly carbide technology, consistently emerged as a key factor for longevity and resistance to breakage – a crucial consideration when working with abrasive metals. Understanding your typical projects will influence whether you prioritize speed or finesse.
Specifications reliably indicate a blade’s physical characteristics – length, width, TPI, and shank type. However, real-world performance and durability are best judged by examining owner feedback. I weighed reports of blades quickly dulling or breaking, as well as comments on cutting speed and smoothness. Reputable tool review sites also provided valuable insights into blade quality and suitability for different metal types. For a refresher on the tool itself, you might find our Sawzall tool guide helpful.
How To Pick The Right metal cutting sawzall blades
Choosing the right blade is critical for clean, efficient cuts and avoiding frustration. A poor blade will wander, bind, and likely break, costing you time and money.
A quality metal-cutting reciprocating saw blade balances durability, tooth geometry, and material composition. Look for blades constructed from high-speed steel (HSS) or bi-metal, with tooth counts (TPI) appropriate for the material thickness. Consider heat treatment processes like cryogenic tempering for increased longevity. Shank compatibility is also essential for universal fit across saw brands.
Tooth Count (TPI) and Material Thickness
The number of teeth per inch (TPI) is the single biggest factor in getting a clean cut. Lower TPI blades (6-14) excel at rapidly removing material from thicker stock, but leave a rougher finish. Higher TPI blades (18-24) are designed for thinner materials, producing cleaner cuts with less vibration, but cut more slowly. Many blades, like the Diablo 9-Inch 14/18TPI blade, feature a dual TPI configuration to offer versatility. Don’t assume “more teeth is always better”; attempting to cut thick steel with a fine-tooth blade will glaze the teeth and dramatically reduce cutting speed.
Blade Material and Durability
Bi-metal blades are the standard for most metal cutting tasks because they offer a good balance of flexibility and toughness. However, the quality of the bi-metal matters. Blades with a higher cobalt content (like the EZARC Cryo Tech 6-Inch 14TPI) are significantly more wear-resistant. These are worth the investment if you cut metal frequently. Carbide-tipped blades, such as the EZARC Carbide 6-Inch 8TPI blade, represent another step up in durability, offering up to 50x the life of a bi-metal blade – though they’re typically more brittle.
Here’s a quick guide to blade material choices:
- Bi-Metal (standard): Good for general metal cutting, reasonable price.
- Bi-Metal (high cobalt): Increased durability for frequent use or harder metals.
- Carbide: Extremely long-lasting, best for very hard or abrasive metals.
A blade’s lifespan is directly related to the quality of its steel and heat treatment. Don’t skimp on blades – a broken blade mid-cut is a frustrating waste of time.
Value and Application Specificity
While a general-purpose blade is useful to have on hand, specialized blades can drastically improve performance for certain tasks. For example, if you frequently work on automotive projects, investing in a blade specifically designed for auto dismantling, like the Diablo blade, makes sense. Similarly, if you need to cut thin sheet metal, a blade like the DEWALT 6-Inch 24TPI blade will prevent tearing and produce a cleaner edge. Consider whether a multi-pack, such as the 25 Pack 9-Inch 14/18TPI blade, offers better value if you burn through blades quickly. Understanding the difference between a Sawzall vs reciprocating saw will also help you select the correct blade. If you’re unsure which blade is best for your needs, exploring metal-cutting reciprocating saw blades can provide a deeper dive.

Frequently Asked Questions
What TPI blade should I use for cutting 1/8-inch steel plate?
A blade with 14-18 teeth per inch (TPI) will work best for 1/8-inch steel plate. This range provides a balance between cutting speed and a reasonably clean finish, avoiding the glazing that can occur with very fine-tooth blades on thicker material.
Are carbide blades really worth the extra cost?
Yes, carbide blades offer significantly longer life, especially when cutting abrasive metals like stainless steel or cast iron. While more expensive upfront, they can save money in the long run by reducing the frequency of blade replacements.
What does “bi-metal” construction actually mean?
Bi-metal blades combine a high-speed steel (HSS) cutting edge welded to a more flexible steel body. This combination provides both hardness for cutting and flexibility to resist breakage, making them the most versatile option for a variety of metal cutting applications.
What shank size do I need to make sure the blade fits my sawzall?
Most modern sawzalls use a 1/2-inch universal shank, but it’s always best to check your saw’s manual to confirm compatibility. Using the wrong shank size can damage the saw or create a dangerous situation. You can find more information on reciprocating saw blades for metals.
How can I extend the life of my metal cutting sawzall blades?
Using a slow and steady cutting speed, applying consistent pressure, and avoiding excessive heat buildup will all help prolong blade life. Selecting the correct TPI for the material thickness and using cutting fluid can also make a significant difference, especially when dealing with harder metals.
The Bottom Line
Choosing a metal-cutting sawzall blade always involves a trade-off between upfront cost and long-term durability. While you can get by with cheaper bi-metal blades, consistently tackling tougher jobs is where the EZARC Carbide 6-Inch 8TPI blade stands out – it’s a worthwhile investment if you need a blade that simply won’t quit.
For those needing a versatile option, the Diablo 9-Inch 14/18TPI blade offers a great balance. If you’re on a tighter budget, or only have occasional metal-cutting tasks, the 25 Pack 9-Inch 14/18TPI blades provide a lot of cutting power for the price. And if you are new to reciprocating saws, researching reciprocating saw operation is a good place to start.
Ultimately, don’t get too hung up on chasing the highest TPI or the newest material. Reliable performance comes down to selecting a blade suited to the type of metal you cut most often, and prioritizing quality construction. A dull or broken blade is far more costly than spending a little extra upfront.
