What Steel are Circular Saw Blades Made of

Last Updated on August 13, 2023

Circular saw blades are primarily made of high-speed steel or carbide-tipped steel. The former is a mixture of various metals, including cobalt and tungsten, while the latter is a hardened steel tip that is welded on to a softer steel body.

Circular saw blades have been an essential tool in woodworking and metalworking since the early 19th century. They consist of a cutting edge with sharp teeth, which allows them to cut through different materials with precision. The blade’s quality is crucial since it determines the accuracy and finish of the final cut.

Therefore, it’s essential to understand the different types of steel used in making circular saw blades. High-speed steel blades are more affordable and ideal for cutting softer materials like wood, while carbide-tipped steel is more durable and suited for cutting harder materials like metals. In this article, we explore the different types of steel used in making circular saw blades and their unique features.

An Introduction To Circular Saw Blades

Circular saw blades are an important tool in woodworking. They are used to cut a variety of materials such as wood, metal, and plastic. Circular saw blades are designed to spin at high speeds, allowing for fast and efficient cutting.

The design of a circular saw blade is critical to its performance. The blade’s teeth must be sharp and properly spaced to achieve optimal results. Additionally, the composition of the circular saw blade is crucial. They are typically made of high-speed steel or carbide.

The choice of material depends on the type of material being cut and the blade’s expected lifespan. Therefore, choosing the right type of circular saw blade is important for success in any woodworking project.

Common Steel Types Used In Circular Saw Blades

Circular saw blades are commonly created with high carbon steel, known for its hardness and toughness. High-speed steel is another frequently used alloy, well-suited for cutting through metals. Carbide tipped blades are often utilized for cutting through hard materials, such as tile and concrete, due to the strength provided by the carbide tips.

Diamond blades are made with a metal core and tiny diamonds embedded into it, providing exceptional cutting power for hard and abrasive materials. The type of steel used in circular saw blades, however, depends on the application and the type of material being cut.

Overall, choosing the right blade for the job is a crucial step in ensuring clean, efficient cuts.

Advantages And Disadvantages Of Steel Types

Circular saw blades can be made from various types of steel, each with its own advantages and disadvantages. High carbon steel blades are known for their affordability and durability but lack in cutting performance for hardwoods and metals. High-speed steel blades can cut through tougher materials and have a longer lifespan than high carbon steel blades but also come with a higher price tag.

Carbide tipped steel blades have excellent cutting performance and can cut through almost any type of material but are the most expensive of the steel blade options. Diamond blades are the most durable and highest performing type of steel blade; however, they are also the most expensive.

It’s important to consider the type of material that will be cut when selecting the appropriate steel blade for a circular saw.

Factors Affecting The Steel Composition Of Circular Saw Blades

Circular saw blades are manufactured in a range of steel compositions that differ depending on a variety of factors. One of the most significant of which is the type of material being cut. Blade thickness is also a crucial factor, affecting the blade’s durability and its ability to cut through denser materials.

Along with blade thickness, the machine’s speed and torque can have an impact on the blade’s composition, as faster machines and lower torque can result in more brittle steel. Lastly, the skill level of the operator can also play a role in determining the composition of steel used for circular saw blades.

These factors all combine to influence the overall quality and durability of the blade. It’s important for savvy shoppers to be aware of these factors when choosing the right blade for their cutting needs.


Based on this detailed guide about the steel used in manufacturing circular saw blades, it’s clear that there are many factors to consider for optimal performance. While the type of steel is important since it determines the hardness and strength of the blade, other factors such as tooth shape, grind and size also play significant roles.

Manufacturers must consider the intended use of the blade and the desired cutting result when selecting the appropriate steel. It’s essential for end users to understand how to choose the right blade for their cutting tasks, taking into account the materials being cut, the desired finish quality, and the machine being used.
