How We Chose These reciprocating saw blades for metals
Rather than a hands-on lab test, my research for these recommendations involved a detailed comparison of published specifications and features across numerous blades. I weighed owner reviews from multiple sources, along with assessments from respected tool review sites, to get a thorough picture of real-world performance. My background maintaining workshops and helping with renovation projects informed how I prioritized those features. Ultimately, I ranked blades against criteria important for metal cutting – durability, speed, and precision.
For metal reciprocating saw blades, the tooth count (TPI) and the blade’s bi-metal construction are critical. A higher TPI generally means finer cuts and better control, especially in thinner metals. Bi-metal construction is essential; it combines a tough body with a harder, wear-resistant cutting edge, preventing breakage when tackling harder alloys. Heat dissipation is also a major factor, as metal cutting generates significant friction.
Specifications reliably indicate TPI, blade thickness, and shank type. However, I relied heavily on owner feedback to gauge long-term durability and how well blades hold an edge. Reputation matters here – established brands with consistently positive reviews tend to deliver on performance promises. Understanding blades for different materials is also key, as the ideal blade changes depending on the type and thickness of metal you’re cutting.
How To Pick The Right reciprocating saw blades for metals
Choosing the right reciprocating saw blade for metal is about more than just grabbing something that fits your saw. It’s about understanding what you’ll be cutting, how often, and what kind of finish you need.
A quality reciprocating saw blade for metal will feature a bi-metal construction for durability, an appropriate teeth per inch (TPI) count for the material thickness, and a robust design to withstand heat and bending during extended use. Look for blades with a reinforced cutting edge, often containing cobalt, and a shank designed for universal compatibility with common reciprocating saws. Proper blade selection maximizes cutting speed, minimizes blade breakage, and delivers cleaner results.
Tooth Count (TPI) and Material Thickness
The number of teeth per inch (TPI) is probably the most misunderstood aspect of reciprocating saw blades. A lower TPI is better for thicker materials, while a higher TPI excels at thinner stock. Generally, 14-18 TPI is a good all-around range for most metalworking, but don’t be afraid to adjust. If you’re working with sheet metal, you’ll want a higher TPI (like 18 or even 24) to prevent the blade from catching and tearing. For thicker pipes or structural steel, drop down to 14 or even 8 TPI for faster cutting. Understanding teeth per inch explained is key to avoiding frustration and broken blades.
Bi-Metal Construction & Cobalt Content
Don’t skimp on blade material. Bi-metal blades are the standard for metal cutting because they combine a flexible backing steel with a harder, more wear-resistant cutting edge. The higher the cobalt content in that cutting edge, the better the blade will hold up to heat and abrasion. Blades like the TOLESA 9-Inch 14TPI Bi-Metal Blades boast extra cobalt (8% in their case) for significantly improved durability.
- A basic bi-metal blade is fine for occasional use on thin materials.
- A blade with 5-8% cobalt is a solid choice for most DIY projects and regular use on medium-thickness metal.
- For professional use or cutting exceptionally hard metals, look for blades with 10% or more cobalt, as these will resist wear and maintain sharpness for longer, making them ideal for metal-cutting blades for tough jobs.
Shank Type and Application-Specific Geometry
While most reciprocating saw blades use a standard 1/2-inch shank for universal compatibility, the blade’s geometry – its shape and tooth pattern – is where things get more nuanced. Some blades, like the Diablo 9” Dual Tooth Bi-Metal Blades, feature a unique tooth configuration designed for specific tasks, in their case, auto dismantling. This dual-tooth design accelerates material removal. Other blades, like the Bosch RM618 6-Inch 18T Metal Blades, are designed for thin sheet metal with a thinner kerf to reduce material waste. Consider your primary application and look for blades specifically engineered for it.
A good rule of thumb is to always wear safety glasses when using a reciprocating saw, and to start your cut slowly to prevent the blade from wandering or catching.

Frequently Asked Questions
What blade TPI is best for cutting thick steel pipes?
A lower TPI, around 8-14, is best for thick steel pipes. This allows for faster material removal and prevents the blade from becoming clogged with metal shavings, something more aggressive cuts generate.
Can I use a standard wood-cutting reciprocating saw blade on metal?
No, you should not use a standard wood-cutting blade on metal. Wood blades lack the necessary tooth hardness and construction to handle the density and abrasive nature of metal, leading to rapid dulling or breakage.
How can I extend the life of my metal reciprocating saw blades?
Using a slow, steady cutting speed and applying moderate pressure will extend blade life. Also, proper lubrication (like cutting oil) reduces heat and friction, preventing premature wear, and storing blades properly prevents rust.
Are more expensive blades always worth the investment?
Generally, yes, more expensive blades offer superior materials and construction. Blades with higher cobalt content and bi-metal construction last longer and cut more efficiently, saving you money in the long run, especially with frequent use.
What blades should I use if I need to cut through hardened metal, like some exhaust systems?
For hardened metal, you’ll want a blade with a high cobalt content (10% or more) and a fine TPI (18-24). Consider blades specifically designed for metal blades for dense materials like cast iron, as they can handle similar levels of hardness.
The Bottom Line
Choosing a reciprocating saw blade for metal often comes down to balancing upfront cost with long-term durability and performance.
