What is the difference between a high-speed steel and carbide table saw blade?

Table saw blades are essential tools in woodworking, and the choice between high-speed steel (HSS) and carbide blades can significantly impact the quality and efficiency of your work. As a table saw blade supplier, I often encounter customers who are unsure about the differences between these two types of blades. In this blog post, I'll delve into the characteristics, advantages, and drawbacks of high-speed steel and carbide table saw blades to help you make an informed decision.

High-Speed Steel (HSS) Table Saw Blades

High-speed steel is a type of tool steel known for its ability to withstand high temperatures without losing its hardness. HSS table saw blades are made from a combination of iron, carbon, and other alloying elements such as tungsten, molybdenum, chromium, and vanadium. These elements enhance the blade's strength, toughness, and heat resistance.

Characteristics of HSS Table Saw Blades

• Sharpness: HSS blades can be sharpened to a very fine edge, which allows for clean and precise cuts. This makes them suitable for cutting a variety of materials, including wood, plastics, and non-ferrous metals.
• Toughness: HSS blades are relatively tough and can withstand the stresses of cutting without chipping or breaking. This makes them a good choice for rough cutting applications where the blade may encounter knots or other hard materials.
• Cost: HSS blades are generally less expensive than carbide blades, making them a more budget-friendly option for DIYers and hobbyists.

Advantages of HSS Table Saw Blades

• Versatility: HSS blades can be used to cut a wide range of materials, including softwoods, hardwoods, plywood, and laminates. This makes them a versatile tool for any woodworking shop.
• Sharpenability: HSS blades can be easily sharpened using a bench grinder or a professional blade sharpener. This allows you to extend the life of the blade and maintain its cutting performance.
• Low Cost: As mentioned earlier, HSS blades are generally less expensive than carbide blades. This makes them a good option for those who are on a tight budget or who only need to make occasional cuts.

Drawbacks of HSS Table Saw Blades

• Heat Resistance: HSS blades are not as heat-resistant as carbide blades, which means they can dull quickly when cutting at high speeds or when cutting hard materials. This can result in a decrease in cutting performance and an increase in the risk of blade damage.
• Wear Resistance: HSS blades are also not as wear-resistant as carbide blades, which means they may need to be replaced more frequently. This can increase the overall cost of using HSS blades over time.

Carbide Table Saw Blades

Carbide is a composite material made from tungsten carbide particles bonded together with a metal binder, usually cobalt. Carbide table saw blades are known for their hardness, wear resistance, and heat resistance, which make them ideal for cutting hard materials and for high-speed cutting applications.

Characteristics of Carbide Table Saw Blades

• Hardness: Carbide is one of the hardest materials available, which means carbide blades can maintain their sharpness for a longer period of time than HSS blades. This allows for cleaner and more precise cuts, even when cutting hard materials.
• Wear Resistance: Carbide blades are highly wear-resistant, which means they can withstand the abrasive forces of cutting without dulling or chipping. This makes them a good choice for cutting materials such as hardwoods, laminates, and composites.
• Heat Resistance: Carbide blades are also highly heat-resistant, which means they can maintain their hardness and cutting performance even when cutting at high speeds or when cutting hard materials. This reduces the risk of blade damage and extends the life of the blade.

Advantages of Carbide Table Saw Blades

• Longevity: Carbide blades can last up to 20 times longer than HSS blades, which means you'll need to replace them less frequently. This can save you money in the long run, especially if you do a lot of cutting.
• Cutting Performance: Carbide blades provide cleaner, smoother, and more precise cuts than HSS blades, which can improve the quality of your work. This makes them a good choice for professional woodworkers and for those who demand the highest level of performance from their tools.
• Versatility: Carbide blades can be used to cut a wide range of materials, including hardwoods, softwoods, plywood, laminates, composites, and non-ferrous metals. This makes them a versatile tool for any woodworking shop.

Drawbacks of Carbide Table Saw Blades

• Cost: Carbide blades are generally more expensive than HSS blades, which can make them a less budget-friendly option for DIYers and hobbyists.
• Sharpenability: Carbide blades are more difficult to sharpen than HSS blades, which means you may need to take them to a professional blade sharpener. This can add to the overall cost of using carbide blades.

Comparison of HSS and Carbide Table Saw Blades

Now that we've discussed the characteristics, advantages, and drawbacks of HSS and carbide table saw blades, let's compare them side by side to help you decide which type of blade is right for you.

Feature	High-Speed Steel (HSS)	Carbide
Sharpness	Can be sharpened to a fine edge	Maintains sharpness for a longer period of time
Toughness	Relatively tough and can withstand stresses	Less likely to chip or break
Heat Resistance	Not as heat-resistant	Highly heat-resistant
Wear Resistance	Less wear-resistant	Highly wear-resistant
Cost	Less expensive	More expensive
Sharpenability	Easy to sharpen	More difficult to sharpen
Versatility	Can cut a wide range of materials	Can cut a wide range of materials, including hard materials
Longevity	Shorter lifespan	Longer lifespan

Choosing the Right Table Saw Blade

When choosing a table saw blade, it's important to consider the type of material you'll be cutting, the thickness of the material, the cutting speed, and your budget. Here are some general guidelines to help you make the right choice:

• Softwoods and Plywood: For cutting softwoods and plywood, an HSS blade with a high tooth count (e.g., 60-80 teeth) is a good choice. This will provide a clean and smooth cut without tearing or splintering the wood.
• Hardwoods and Composites: For cutting hardwoods and composites, a carbide blade with a high tooth count (e.g., 80-100 teeth) is recommended. This will provide a clean and precise cut, even when cutting hard materials.
• Laminates and Plastics: For cutting laminates and plastics, a carbide blade with a special coating or tooth geometry is recommended. This will help to prevent chipping and melting of the material.
• Non-Ferrous Metals: For cutting non-ferrous metals, an HSS blade with a low tooth count (e.g., 24-30 teeth) is a good choice. This will provide a fast and efficient cut without overheating the blade.
