Common Milling Cutter Materials and Their Differences

2025-09-05
1. High-Speed Steel (HSS)

  • Features: Low cost, good toughness, less prone to chipping, suitable for low/medium-speed cutting.

  • Disadvantages: Poor wear and heat resistance, short tool life on hard materials.

  • Applications: General steels, aluminum, low-hardness alloys; low-speed machining and small batch production.

2. Cobalt High-Speed Steel (HSS-Co, e.g., M35/M42)

  • Features: Added cobalt improves hot hardness and heat resistance compared to regular HSS.

  • Disadvantages: More expensive than HSS, still less wear-resistant than carbide.

  • Applications: Stainless steel, heat-resistant alloys, medium-strength cutting.

3. Solid Carbide

  • Features: Very high hardness (HRA 89–93), excellent wear and heat resistance, suitable for high-speed cutting.

  • Disadvantages: Lower toughness than HSS, more brittle, requires rigid machines and setups.

  • Applications: Mass production, hard materials (HRC 45–65), mold steel, cast iron, alloy steel, stainless steel.

4. Coated Carbide

  • Common Coatings: TiN, TiAlN, AlTiN, DLC, etc.

  • Features: Enhanced wear and heat resistance, reduced friction.

  • Advantages: Longer tool life, higher cutting speeds possible.

  • Applications: High-speed, high-efficiency machining; excellent for difficult-to-machine materials (titanium alloys, high-hardness steels).

5. Ceramic / CBN / PCD

  • Ceramic: High temperature resistance, ideal for high-speed cutting of cast iron and heat-resistant alloys, but low toughness.

  • CBN (Cubic Boron Nitride): Hardness second only to diamond, perfect for hardened steel (HRC 60+) finishing.

  • PCD (Polycrystalline Diamond): Extremely hard, excellent wear resistance, suitable for aluminum, copper, non-ferrous metals, composites; not suitable for steel.
