What Are TCT Circular Saw Blades?

TCT (Tungsten Carbide Tipped) circular saw blades are specialized cutting tools designed for use in various woodworking and metalworking applications. The blades are characterized by their tungsten carbide tips adhered to a steel body, which delivers superior performance and longevity.

Key Features of TCT Circular Saw Blades

  1. Durability: The tungsten carbide tips are known for their exceptional hardness, allowing the blades to withstand high temperatures and resist wear.
  2. Versatility: TCT circular saw blades can cut through a wide range of materials, including hardwood, softwood, plywood, and even certain metals.
  3. Precision: These blades are engineered for clean cuts, providing a smooth finish on the material being cut.
  4. Different Tooth Configurations: TCT circular saw blades come in various tooth shapes and configurations, suited for different cutting applications:
    • Flat Top Grind (FTG): Ideal for ripping wood.
    • Alternate Top Bevel (ATB): Perfect for crosscutting.
    • Triple Chip Grind (TCG): Designed for cutting harder materials.

Applications of TCT Circular Saw Blades

TCT circular saw blades are suitable for a variety of applications, making them a go-to choice for many professionals. Common uses include:

  • Woodworking: For making precise cuts in plywood, MDF, and hardwood.
  • Metalworking: To cut through non-ferrous metals such as aluminum or brass.
  • Construction: Useful for framing and decking projects.
