What Steel Are Circular Saw Blades Made Of?
Circular saw blades are essential tools used in various woodworking and construction projects. They come in different sizes and styles, but one crucial aspect to consider is the material they are made of. The type of steel used in circular saw blades greatly affects their performance, durability, and cutting efficiency. In this article, we will explore the different types of steel commonly used to manufacture circular saw blades, their properties, and their advantages and disadvantages.
1. High-Speed Steel (HSS)
High-speed steel (HSS) is a type of tool steel that is commonly used in the manufacturing of circular saw blades. HSS blades are made from an alloy of steel, which contains elements such as cobalt, tungsten, molybdenum, and vanadium. These additional elements enhance the blade’s hardness, toughness, and heat resistance.
HSS circular saw blades are known for their excellent cutting performance and longevity. They can withstand high temperatures generated during cutting, making them ideal for cutting through hard materials such as stainless steel, hardwood, and metal alloys. Additionally, HSS blades can be sharpened multiple times, extending their lifespan and saving on replacement costs.
However, HSS blades are relatively expensive compared to other steel types. They are also not suitable for cutting through abrasive materials as the high-speed steel may wear down quickly. Nevertheless, HSS circular saw blades remain a popular choice for professionals due to their superior cutting abilities and durability.
2. Carbide-Tipped Steel
Carbide-tipped circular saw blades are designed for heavy-duty cutting applications. These blades are made from a combination of high-speed steel and carbide tips. Carbide is a compound made from tungsten and carbon, which significantly improves the blade’s hardness and resistance to wear.
The carbide tips are welded or brazed onto the blade’s teeth, providing extra strength and durability. This design allows the blade to maintain its sharpness even when cutting through abrasive materials such as laminates, plywood, and hard plastics. Carbide-tipped blades are also excellent for cutting through non-ferrous metals like aluminum or copper.
One notable advantage of carbide-tipped circular saw blades is their extended longevity. These blades can withstand heavy usage and retain their sharp cutting edges, reducing the frequency of blade replacements. However, carbide-tipped blades can be more expensive than HSS blades, making them more suitable for professionals or users with high-volume cutting needs.
3. Diamond-Tipped Steel
Diamond-tipped circular saw blades are the pinnacle of blade technology. These blades utilize small pieces of synthetic diamonds embedded onto their cutting edge. Diamond is known for its exceptional hardness, making it perfect for cutting through extremely hard and abrasive materials.
Diamond-tipped circular saw blades are commonly used in cutting applications that involve stone, concrete, ceramics, and other similar materials. They offer unparalleled cutting performance and can withstand the high temperatures generated by friction during cutting. Additionally, diamond-tipped blades produce clean and precise cuts, which is crucial for certain applications like tile installations.
However, diamond-tipped circular saw blades come with a higher price tag compared to other types of blades. The cost of the synthetic diamonds used in their manufacturing process contributes to the overall expense. These blades are also not suitable for cutting through metals or wood, as the diamonds may become damaged or worn down. Diamond-tipped blades are primarily used by professionals who require precise and efficient cutting in specialized applications.
4. Bimetal Steel
Bimetal circular saw blades are made from two distinct types of steel, hence the name “bimetal.” The central core of the blade is made of alloy steel while the teeth are made of high-speed steel or carbide. This combination provides the best of both worlds: the durability and flexibility of high-speed steel or carbide and the cutting efficiency of alloy steel.
Bimetal blades are suitable for a wide range of cutting applications, including wood, plastic, and metal. The teeth can withstand high speeds and resist chipping or dulling, while the alloy steel core offers flexibility to prevent the blade from snapping during intense cutting. The ability to cut through multiple materials without constant blade changes makes bimetal circular saw blades popular among professionals and DIY enthusiasts alike.
One of the downsides of bimetal blades is their higher cost compared to regular steel blades. However, the versatility and extended lifespan of these blades often make them a worthwhile investment for those who require cross-cutting capabilities.
5. Carbon Steel
Carbon steel is an alloy of iron and carbon, with other elements added to enhance specific properties. Circular saw blades made from carbon steel are less expensive than their high-speed steel or carbide counterparts. These blades offer decent cutting efficiency and are suitable for cutting softwoods, plywood, and some non-abrasive materials.
While carbon steel blades are affordable, they tend to wear down more quickly and may require frequent sharpening or replacement. They are not recommended for heavy-duty cutting or cutting through hard materials, as the blades may become dull or damaged easily. Carbon steel blades are more commonly used by hobbyists or occasional users who do not require precision cutting or extended blade life.
6. Stainless Steel
Stainless steel circular saw blades are specifically designed for cutting through stainless steel materials. These blades are made from stainless steel alloys that provide excellent corrosion resistance and durability.
Stainless steel blades have a higher chromium content, which enhances their resistance to heat and friction during cutting. They are specially hardened to withstand the challenges of cutting through stainless steel without becoming dull or damaged quickly.
While stainless steel blades are relatively more expensive than regular steel blades, they offer superior performance and longevity when it comes to cutting stainless steel materials. These blades are essential for professionals in the metalworking industry, as they ensure clean and precise cuts without compromising the integrity of the stainless steel.
7. Cobalt Steel
Cobalt steel is a type of alloy steel that contains a significant amount of cobalt in its composition. Circular saw blades made from cobalt steel are known for their exceptional heat resistance and cutting performance.
Cobalt steel blades can withstand high temperatures generated during cutting, making them suitable for cutting through tough and heat-resistant materials. They are commonly used for cutting stainless steel, cast iron, and other high-alloy materials. The cobalt content in these blades enhances their hardness, ensuring long-lasting cutting edges.
However, cobalt steel blades are more expensive than regular steel blades due to their higher cobalt content. They are typically used by professionals or those who require precise and efficient cutting in demanding applications.
