Circular saw blades are mainly made from high-speed steel (hss) or carbide-tipped steel. Hss blades are cost-effective and ideal for cutting softer materials, while carbide-tipped blades are more durable and suited for cutting harder materials.
Circular saw blades are a necessary tool for any individual who works in the fields of construction, woodworking, or metalworking. The quality and durability of the blade primarily depend on the material it is made of. When it comes to circular saw blades, you must know what type of steel they are made of, as it determines the type of material they can cut and their lifespan.
Hss blades are budget-friendly, relatively soft and are best suited for cutting wood and other soft materials. Carbide-tipped steel blades, on the other hand, are much more durable, can handle harder materials, and are more expensive than hss blades. This article will guide you through the different types of circular saw blades and the materials they are made from.
Defining Circular Saw Blades
Circular saw blades vary in diameter, thickness, and material, but they all follow the same general design. The blades consist of a metal disk with teeth along the edge that can cut through wood, metal, and other materials. the most common type of steel used for circular saw blades is high speed steel (hss).
Hss blades can tolerate high temperatures and maintain their hardness, which makes them suitable for cutting strong materials like metal. Another material is carbide-tipped, which combines tungsten carbide with steel. This material is more durable and lasts longer than hss.
Some other variations include diamond-tipped blades specially designed for cutting concrete or tiles, and blades with a combination of different types of teeth for cutting through various materials. When choosing a circular saw blade, consider the type of material you will be cutting and choose the appropriate blade for the job.
The Evolution Of Circular Saw Blades
Circular saw blades are an essential tool for construction work and woodworking projects. The first circular saw blade origins date back to the early 19th century. In those days, the blades were made of steel that was difficult to shape because of its brittleness.
Over time, improvements in technology resulted in more durable and flexible materials. Nowadays, circular saw blades are manufactured from high-quality steel specifically designed for this purpose. The steel used in these blades usually has a combination of elements such as tungsten, carbon, cobalt, and chromium, which make the blades shock and heat-resistant.
The evolution of circular saw blades reflects how technological advances have positively influenced construction and woodworking industries.
Introduction To Steel
Steel is a crucial material used in various industrial and construction applications, including circular saw blades. It boasts high strength, durability, and resistance to corrosion, making it ideal for cutting tough materials. Steel is a blend of iron and carbon, with additional elements providing additional properties, such as nickel, chromium, and molybdenum.
Carbon concentration affects steel’s strength and toughness, and the higher the carbon content, the more brittle the steel becomes. The process of making steel involves melting iron ore with coke and limestone, and then purifying the molten iron through a process called refining.
Steelmakers control the alloy’s properties by adding alloys and adjusting the carbon concentration. Steel properties depend on its chemical composition, heat treatment, and processing. Understanding these properties is crucial in selecting the best steel for circular saw blades applications.
Types Of Steel Used In Circular Saw Blades
Circular saw blades require different types of steel depending on the application. High carbon steel is popular because of its ability to retain sharp edges even with heavy usage. Stainless steel is also becoming a popular choice for those who want a long-lasting and rust-resistant blade.
Carbon steel is commonly used for saw blades because of its excellent toughness and durability. Diamond-tipped steel is known for its extreme hardness and excellent performance for cutting hard materials, while carbide steel is great for precision cutting and is used in more specialized applications.
Each type of steel has its own unique advantages, and the decision on which to use will be determined by the conditions in which the saw blade will be used.
Unique Steel Properties
Circular saw blades are made of unique steel properties that provide exceptional strength and durability. To withstand the rigors of heavy-duty cutting, these blades must also exhibit wear resistance and heat resistance. Impact resistance and hardness are equally essential for enduring continuous use without losing their sharpness.

Steel Preparation For Circular Saw Blades
Circular saw blades are made using high-speed steel that consists of tungsten, vanadium, molybdenum, and cobalt. The steel undergoes a critical preparation process, including melting and pouring, forming and rolling, and heat treatment. During melting and pouring, the steel is melted in a furnace to remove impurities and adjusted to the desired chemical composition.
The molten metal is then poured into molds and cooled. The formed steel is also rolled and shaped into the desired thickness and size. Heat treatment, the next step, involves the heating and cooling of steel to enhance toughness and durability.
The resulting circular saw blades have high resistance to wear and tear and can cut through various materials with efficiency and precision.
Manufacturing Circular Saw Blades
Circular saw blades are typically made from high-grade steel. The manufacturing process begins with annealing, a heat treatment to remove internal stresses and improve the steel’s ductility. After annealing, the steel is hardened to increase its durability and resistance to wear.
This is achieved through a quenching process, in which the steel is rapidly cooled to room temperature from a high temperature. Finally, the surface of the saw blade is finished through active or passive surface finishing techniques. The goal is to reduce friction during cutting and to protect the blade from corrosion.
Overall, the manufacturing process for circular saw blades involves multiple stages of heat and pressure treatments to create a durable, long-lasting cutting tool.
Performance Testing Of Circular Saw Blades
Circular saw blades are typically made from steel, but what type of steel depends on the specific application and desired performance. Performance testing of circular saw blades can help determine the best type of steel for a particular cutting task.
The mechanics of cutting include parameters such as blade material, blade design, and cutting speed. Hardness tests can determine the overall hardness of the blade, while wear tests measure the blade’s resistance to wear and tear over time. Ultimately, choosing the right steel for a circular saw blade can greatly affect its performance, longevity, and efficiency.
