How We Chose These reciprocating saw blades for metals
As someone who’s spent years around power tools and workshops, I know choosing the right blade is as important as the saw itself. Rather than a hands-on lab test with each blade, this research focused on a detailed comparison of published specifications and features. I weighed owner reviews from multiple sources against professional assessments, applying my experience to identify patterns in performance and durability. The goal was to rank these blades based on real-world applicability, not just marketing claims.
For metal-cutting reciprocating saw blades, tooth count and material construction are paramount. Blades with higher TPI (teeth per inch) generally excel at thinner metals and offer cleaner cuts, while lower TPI blades are better suited for thicker stock. Carbide teeth offer significantly longer life when cutting harder materials, but bi-metal blades provide a good balance of durability and cost for general use. These factors heavily influenced my ranking, prioritizing blades designed for specific metal types and thicknesses.
Specifications reliably indicate a blade’s physical dimensions and material composition. However, owner feedback proved crucial for gauging how those specs translate into actual performance – things like resistance to bending, chatter, and overall lifespan. Reputation also played a role; brands known for quality manufacturing and consistent performance received more weight in my assessment. You’ll find more details on specific materials like cast iron using resources like our guide to reciprocating blades for cast iron.
Choosing The Right reciprocating saw blades for metals
Choosing the right reciprocating saw blade for metal isn’t just about finding one that fits your saw; it’s about understanding the metal you’re cutting and how the blade’s construction impacts performance and lifespan.
A quality metal-cutting reciprocating saw blade needs a robust tooth design, appropriate TPI (teeth per inch) for the material thickness, and a flexible yet durable body. Look for blades constructed from bi-metal or carbide, with attention paid to tooth geometry and heat treatment. Consider the specific alloy being cut – stainless steel demands different blade characteristics than mild steel or cast iron.
Tooth Count (TPI) and Material Thickness
The number of teeth per inch (TPI) is perhaps the most critical factor. A lower TPI (6-10) is aggressive, moving material quickly but often leaving a rougher cut. These are best for thicker metals. Higher TPI (18-24) delivers cleaner, more precise cuts in thinner sheet metal, but can clog easily if forced through material that’s too thick. I often recommend starting with an 8 or 10 TPI blade for general metal work and adjusting from there. Don’t expect a single blade to excel at everything – specialized blades are the key to efficiency.
Blade Material: Bi-Metal vs. Carbide
For most homeowners and DIYers, bi-metal blades offer a good balance of performance and cost. They combine a high-speed steel tooth edge bonded to a flexible carbon steel body. However, for tougher jobs and harder alloys, carbide-tipped blades are a worthwhile investment. You’ll pay more upfront, but they’ll last significantly longer, especially when metal-cutting reciprocating blades are used on stainless steel or hardened tool steel.
Here’s how blade material choices typically break down:
- Bi-Metal: Good all-around performance for general metal cutting.
- Carbide: Exceptional durability for tough metals, but more expensive.
- High-Speed Steel (HSS): Typically found on cheaper blades; wears quickly and best for softer metals or light-duty tasks.
Shank Type and Blade Length
While most reciprocating saws use a standard 1/2-inch universal shank, double-check compatibility before you buy. Blade length is also important. A longer blade is helpful for reaching into tight spaces, but can flex and bind more easily, especially in thicker materials. I generally suggest using the shortest blade possible that will safely complete the cut. For cutting through thick steel or cast iron, consider blades for thick metal cutting.
Don’t try to force a blade through material. Let the saw do the work, applying steady pressure and maintaining a consistent speed. A dull blade will only generate more heat and wear, shortening its lifespan and potentially damaging your workpiece.

Frequently Asked Questions
What TPI blade should I use for cutting 1/8″ steel plate?
A blade with 8-10 TPI is generally best for 1/8″ steel plate. Lower tooth counts remove material faster in thicker stock, whereas higher TPI blades tend to clog when pushed through material they aren’t designed for.
Are carbide reciprocating saw blades really worth the extra cost?
Yes, carbide blades are worth the investment if you frequently cut very hard metals like stainless steel or hardened tool steel. While more expensive initially, they offer significantly greater longevity than bi-metal blades when working with abrasive materials.
Can I use a wood-cutting reciprocating saw blade on metal?
No, you shouldn’t use a wood-cutting blade on metal. Wood blades lack the hardened teeth needed to cut metal and will dull very quickly, potentially damaging the blade and the saw. Using the wrong blade is also a safety hazard.
What does shank type mean and why does it matter?
Shank type refers to the attachment point of the blade to the saw. Most reciprocating saws use a 1/2-inch universal shank, but some models require a different size, so checking compatibility is vital before purchasing.
I’m struggling to cut through a thick piece of steel; what am I doing wrong?
You might be trying to cut too quickly or using a blade that isn’t designed for sawzall blades for thick metals. Reduce your speed, apply steady pressure, and ensure you’re using a lower TPI blade appropriate for the steel’s thickness.
The Bottom Line
Choosing a reciprocating saw blade for metals always involves a trade-off between initial cost and long-term durability. While cheaper blades might seem appealing, the frustration of frequent replacements and poor performance can quickly outweigh the savings. For most users, the EZARC Carbide R678HM strikes the best balance, offering a durable carbide edge and versatile TPI for a wide range of metal cutting tasks.
If you’re on a tighter budget, the AMARTISAN 6″ Heavy Metal blades are a solid choice, providing decent performance for lighter-duty applications. For those who frequently tackle challenging cuts – like thick steel or stainless steel – or need a blade for blades for steel pipe cutting, the Diablo Steel Demon Carbide is worth the investment.
Ultimately, remember that the right blade isn’t about a single specification. Focusing on matching the TPI to your material thickness, selecting the appropriate material (bi-metal or carbide) for the metal type, and maintaining a steady cutting technique will deliver far better results than chasing the highest number on a spec sheet.
