There is no single steel used in every circular saw blade; what steel are circular saw blades made from depends on the blade’s construction. Some designs have solid-steel teeth, while many modern blades use separate cutting tips made from tungsten carbide or a cobalt alloy such as Stellite.[1][2] For a closer look, read How to Use a Circular Saw Safely and Accurately.
That distinction helps you compare blades without treating “steel” as a complete description of the cutting edge. A blade with solid-steel teeth and one with separate tips are different constructions, so look at the material description in light of the blade’s intended cutting task. This section focuses on blade materials and construction, not installation or general saw operation.
Two common tooth constructions
On a solid-tooth blade, the teeth are part of the blade’s steel material; nickel tool steel is reported as a material generally used for saw blades and solid-tooth saw teeth.[2] That is a reported material, not a rule that every solid-tooth blade uses the same steel. If a product description names a steel grade, treat it as information about that particular product rather than a universal answer.
Many modern circular blades instead have separate tips, including tungsten-carbide or cobalt-alloy tips.[1] The word “steel” alone therefore may not tell you what material forms the cutting edge. When you compare two blades, distinguish a solid-tooth construction from one with separate tips, then consider the materials named for that design.
What to look for when comparing blades
Start with the manufacturer’s description of the specific blade. Check whether it identifies solid-steel teeth or separate tips, and read the stated application alongside that construction. For example, if one description names carbide tips and another describes solid-steel teeth, you are comparing different designs—not simply two labels for the same material.
Use the blade’s stated task to guide your choice rather than assuming that one steel type suits every cut. If a description does not name a steel grade, you can still compare the construction and intended application without guessing. Keep the question focused on what the blade is made from and what kind of cutting it is intended for; installation and general saw-use guidance are separate concerns.

What steel forms the blade body?
The blade body is a steel plate that supports the teeth and withstands the forces of cutting. Its steel is not necessarily the same across blade designs, so treat any named grade as an example tied to a particular product or application.
Steel in the blade body
A blade body has to hold its shape while the teeth engage the work. Think of the plate as the structure behind the cutting edge: it supports the teeth and takes the forces passed through the blade as you cut. The steel choice therefore describes the body, not automatically the material at the cutting edge.
One maker-specific example for carbide-tipped blades is high-carbon, high-chromium steel, identified as 1075 Cr1. That example describes the maker’s own blades; it should not be read as a standard for every carbide-tipped circular saw blade. [3]
Nickel tool steel is another reported material for saw blades, including the sawteeth of solid-tooth designs. This is a reported general description, not proof that every blade body or solid-tooth blade uses nickel tool steel. [2]
Why sawmill steel may differ
A lumber-mill blade is a different context from a common portable woodworking blade. L-6 steel is reported for band or circular saw blades used in most lumber mills, so sawmill examples should not be treated as a universal description of portable circular-saw blade bodies. [4]
For example, seeing a lumber-mill blade described as L-6 does not tell you that a portable blade for a shop saw uses the same steel. Likewise, the high-carbon, high-chromium example applies to one maker’s carbide-tipped blades, not to all saw blades. [3][4]
When comparing body materials, keep the specific construction and application in view. A listed steel description can help explain what the plate is made from, but it should not be stretched into a claim about every blade in the same broad category.
What are the teeth made from?
Many modern circular saw blades use separate cutting tips made from tungsten carbide or a cobalt alloy, while solid-tooth blades have teeth formed from the blade material itself.[1][2] That distinction helps you tell what part of the blade does the cutting: on a tipped blade, the tooth tips are a different material from the steel plate behind them.[5]
Separate tips on many blades
A tipped blade combines a steel backing with cutting tips of another material.[5] The tips may be tungsten carbide or a cobalt alloy such as Stellite.[1] For example, if a blade is described as carbide-tipped, “carbide” describes its cutting tips, not the entire blade.
This construction differs from a blade whose teeth are solid steel. The teeth on a solid-tooth saw are part of the blade material rather than separate pieces attached as tips.[2] So, when comparing two blades, look at whether the cutting edge is a separate tip or part of the blade itself.
What the material description means
A carbide-tipped blade still has a steel body; carbide refers to the material at the cutting edge.[5] In practical terms, picture a steel plate carrying small, distinct tips at its rim, rather than a blade made entirely of carbide. A product description that names carbide tips is identifying the cutting material, not replacing the steel body with carbide.
The material label alone does not tell you that every blade has the same construction. A blade with separate alloy or carbide tips and a solid-tooth steel blade are different designs, so check the product description for how its teeth are made. If you are comparing blades for a project, note whether the listing specifies tungsten-carbide tips, cobalt-alloy tips, or solid steel teeth instead of treating “steel blade” as a complete description.
How does material choice affect durability and use?
Treat the blade’s steel body and cutting teeth as one system: choose the construction for the material you plan to cut, not by a steel label alone. A carbide-tipped blade and a solid-tooth steel blade are different designs, so the best fit depends on the blade’s stated application and your task. [1]
Match the construction to the cut
A carbide-tipped blade combines a steel backing with a different material at the cutting edge; a solid-tooth design uses steel teeth formed as part of the blade. [1][5] That difference matters when you compare products: look at the full construction and intended use, rather than treating “steel,” “carbide,” or another material name as a complete description of how the blade is meant to work.
For example, if you are comparing a blade described for cutting wood with one described for another material, use each blade’s stated application to guide your choice. Don’t assume that a particular tooth or body material makes a blade suitable for every cut. Follow the manufacturer’s description of the material and task, and choose a blade that names the work you plan to do.
Be cautious with reclaimed blades
A used blade’s appearance is not a reliable way to identify its steel grade or determine its intended application. Two blades may look similar while having different constructions, so avoid choosing a reclaimed blade based on a guess about its metal. Check for product markings or a manufacturer description when available; if you can’t verify what it is intended to cut, choose a blade with a clear application instead.
Material names also don’t tell you everything about durability or cutting performance on their own. The steel body and tooth material work together, and a blade’s suitability depends on its stated use. Compare the complete blade description with the material and cut you have in mind, rather than trying to infer performance from one label or from appearance.
How can you identify a blade’s materials?
Read the blade’s product description to identify its body steel and tooth or tip material separately; don’t assume one material label describes the whole blade. If you’re comparing two products, look for each material in the manufacturer’s own specifications rather than relying on a broad description such as “steel blade.”
Check the body and cutting edge separately
Start with the material listed for the blade plate or body, then check what the product says about its teeth or tips. A description might give a steel grade for the plate and name a different material for the cutting tips. The two details answer different questions, so keep them separate when comparing blades.
For example, a maker-specific description reports high-chrome, high-carbon steel identified as 1075 Cr1 for its own tungsten-carbide-tipped saws. That grade is an example tied to those blades, not a general specification for every circular saw blade. [3] Don’t use that example to label a different blade unless its manufacturer lists the same grade.
Some descriptions discuss a flexible steel backing paired with another material, but that wording alone may not tell you the exact grade used in a particular product. [5] Check the specific product’s material details before treating a general construction description as a precise steel designation.
Treat grades as product-specific
A steel grade is useful only when the product description connects it to the blade you’re considering. If one listing names a grade and another says only “alloy steel,” you do not have enough information to conclude that the blades use the same steel—or that one is better for your work.
Keep the manufacturer’s wording intact when you compare products. For example, record “1075 Cr1” only for the blade whose description names it, and leave the grade unfilled for a listing that gives no grade. This avoids turning a detail from one product into an assumed standard for all blades.
When the grade isn’t listed
If the manufacturer does not state a steel grade, don’t guess from the blade’s appearance or from another model’s specifications. Use the stated application and construction to decide whether the product is a fit for your task, and treat the exact grade as unknown.
For instance, if a product description identifies its intended cutting use and describes the blade’s construction but gives no steel grade, compare those stated details with the job you have in mind. If knowing the grade matters to your choice, ask the manufacturer for the material specification rather than inferring it from a label or photo.
The practical takeaway
The practical takeaway is that circular saw blades can combine different steel bodies with different tooth constructions, so check the specific blade rather than assuming every blade uses the same material. Many blades pair a steel plate with separate, harder cutting tips: tungsten carbide and cobalt-alloy tips are examples of this construction. [1]
For a woodworker comparing blades, the useful question is not simply “What steel is it?” Look at the blade’s stated material and intended use together. For example, if you are choosing a blade for a particular cutting task, use the product description to confirm what the maker says about its construction and what work the blade is meant to do. Don’t infer a material grade from the blade’s appearance or from another blade that looks similar.
The construction can differ even among blades sold for circular saws. Some use teeth that are part of the blade material, and saw teeth in solid-tooth designs are generally made from nickel tool steel. [2] Other blades use separate tips attached to a steel plate; a maker-specific example describes high-carbon, high-chromium steel for the plate of its tungsten-carbide-tipped blades. [3] Those examples are not a universal specification, so treat a named steel grade as applying only to the product it describes.
Before you buy or reuse a blade, check the product information for its stated body material, tooth or tip construction, and intended cutting use. If the exact steel grade is not listed, rely on the stated application and construction instead of guessing. That gives you a practical basis for comparing blades without treating one material description as a rule for every circular saw blade.
