- Higher cost
- Limited TPI for fine cuts
When cutting through high-strength alloys, cast iron, or thick stainless steel, the Diablo Steel Demon blades stand out on paper for one reason: carbide teeth. Most reciprocating saw blades rely on bi-metal construction, but Diablo went all-in with TiCo Hi-Density carbide tips designed specifically for extreme metal. Owners consistently report these last far longer than standard blades when tackling materials over 3/16 inch thick. The 3 TPI design isn’t for finesse, it’s for aggressive removal, and the 1-inch oversized body helps reduce vibration, which matters when you’re fighting through dense metal.
The Perma-SHIELD coating is a smart touch, helping resist heat buildup and gumming, two common failure points in long cuts. Compared to bi-metal options like the DEWALT DW4813, these aren’t for thin sheet metal or delicate work. But if you’re regularly slicing through structural steel or rebar, the durability payoff is real. I’d pick these over standard blades any day for heavy demolition where blade changes eat up time.

How We Tested metal cutting blade for reciprocating saws
My research involved a detailed comparison of published specifications and features across numerous metal cutting blades. I weighed owner reviews from a variety of sources – including major retailers and tool-focused forums – alongside expert opinions from sites dedicated to construction and metalworking. Rather than a hands-on lab test, this is a research-led comparison focusing on blade geometry, materials, and reported performance in real-world applications. This allowed me to rank blades against clear criteria for different cutting needs.
For metal cutting blades, tooth count (TPI) and blade material are paramount. A higher TPI generally means finer cuts and is better for sheet metal, while a lower TPI excels at thicker stock. The shift towards carbide teeth is also significant; they offer drastically longer life when tackling harder metals, though at a higher initial cost. Blade thickness impacts accuracy and speed, and a flexible body is essential to prevent breakage during demanding cuts. Understanding these factors is key to choosing the right blade.
Specifications reliably indicate blade dimensions, tooth count, and shank type. However, real-world durability and cutting speed require analyzing owner feedback. Reports of premature wear, chipping, or difficulty cutting specific metals are heavily considered. Reputation matters, too – established brands with a history of quality often deliver more consistent performance, and I factored that into the assessments. For more information on getting the most out of your saw, read up on reciprocating saw operation tips.
How To Choose The metal cutting blade for reciprocating saws
Finding the right metal cutting blade for your reciprocating saw isn’t just about grabbing the cheapest option. It’s about matching the blade’s characteristics to the type and thickness of metal you’ll be working with.
A quality metal cutting blade balances durability, cutting speed, and finish. Key considerations include the blade’s material (bi-metal or carbide), teeth per inch (TPI), blade thickness, and shank type. Prioritize blades designed for the specific metal you’re cutting, stainless steel requires different geometry than mild steel or aluminum.
Material: Bi-Metal vs. Carbide
The core material of the blade dictates its lifespan and what metals it can effectively cut. Bi-metal blades, as the name suggests, combine a high-speed steel tooth with a more flexible backing steel. They offer a good balance of durability and cost-effectiveness, making them ideal for general purpose metal cutting. However, for tougher materials like hardened steel, stainless steel, or cast iron, carbide blades are the way to go. Carbide teeth are significantly harder and more wear-resistant than high-speed steel, resulting in a dramatically longer blade life, some claim 50x or even 100x longer. While more expensive upfront, a carbide blade will save you money in the long run when tackling demanding projects.
Teeth Per Inch (TPI) and Cutting Finish
The number of teeth per inch explained is critical for achieving a clean cut and maximizing cutting speed. Lower TPI blades (around 8-14) are best for thicker metals, as the larger gullets between the teeth allow for more efficient chip removal. Higher TPI blades (18-24+) excel at cutting thinner sheet metal and produce a finer finish. Using the wrong TPI can lead to rough edges, excessive heat buildup, and premature blade wear.
Here’s a breakdown to help you choose:
- 6-8 TPI: For cutting through very thick metal (over 1/4 inch).
- 14 TPI: A versatile option for general metal cutting, good for pipes and moderate thicknesses.
- 24+ TPI: Best for thin sheet metal and when a clean, burr-free edge is essential.
Don’t underestimate the impact of TPI. A blade with too few teeth will chatter and strip, while one with too many will clog and overheat.
Blade Thickness and Application
Beyond material and TPI, consider the blade’s thickness. Thicker blades are more durable and resist bending, making them suitable for demolition work and rough cuts. Thinner blades, like those around .035 inches, offer more flexibility and are ideal for intricate cuts and working in tight spaces. When choosing a blade, think about the specific application. Are you cutting through stacked plates of steel, or are you trimming sheet metal for a DIY project? Finding the right balance between durability and flexibility will improve your cutting efficiency and prevent blade breakage. If you’re looking for a good all-around option, exploring different metal-cutting Sawzall blades is a great place to start.

Frequently Asked Questions
What blade TPI is best for stainless steel?
A higher TPI (18-24+) is generally best for stainless steel. Finer teeth create less heat and prevent work hardening, which can quickly dull a blade when cutting this material.
Are carbide blades really worth the extra cost?
Yes, carbide blades are worth the investment if you frequently cut harder metals. They last significantly longer than bi-metal blades, potentially saving you money and downtime over time, especially when working with materials like cast iron.
What does shank size matter for reciprocating saw blades?
Shank size determines compatibility with your saw. Most reciprocating saws use a 1/2-inch shank, but some older models or specialty saws may require different sizes, so check your saw’s manual.
How can I prevent a metal cutting blade from overheating?
Reducing cutting speed and applying a cutting lubricant can help manage heat. Using the correct TPI for the metal’s thickness also minimizes friction and heat buildup; consider blades for steel pipes for optimal performance.
Can a reciprocating saw blade cut through hardened steel?
While possible, cutting hardened steel requires a high-quality carbide blade and patience. Hardened steel is extremely abrasive, so expect a slower cutting speed and increased blade wear, even with a carbide blade designed for tough materials.
