The materials of woodworking tools include hard alloy, high-speed steel, and diamond. What is the difference between them?

The materials used in woodworking tools, including hard alloy, high-speed steel, and diamond, have distinct characteristics:

1.Hard Alloy (Tungsten Carbide):

  - Composition: Contains tungsten carbide as the primary component, often with cobalt or other binding metals.

  - Characteristics: Known for high hardness, wear resistance, and toughness, making it suitable for cutting and shaping wood.

  - Applications: Widely used in woodworking for drill bits, saw blades, and cutting tools due to its durability.

2. High-Speed Steel (HSS):

  - Composition: Alloy steel containing elements like tungsten, molybdenum, chromium, and vanadium.

  - Characteristics: Exhibits high heat resistance, hardness, and toughness, allowing for fast cutting speeds without losing edge sharpness.

  - Applications: Ideal for woodworking tools requiring high cutting speeds, such as drills, saw blades, and milling cutters .

3. Diamond:

  - Composition: Consists of crystalline carbon.

  - Characteristics: Exceptionally hard and durable, offering superior cutting performance and longevity.

  - Applications: Used in woodworking for specialized tasks where extreme hardness and abrasion resistance are required, such as cutting hard materials or achieving precision finishes .

Each material has its advantages and is chosen based on the specific requirements of the woodworking application, considering factors like cutting speed, material hardness, and desired finish.
