Material & Coating Details:

• M42 HSS:

  • A cobalt-bearing high-speed steel with excellent hardness, wear resistance, and red hardness.
  • Ideal for high-performance cutting tools and punches that require durability.
  • Composition: 8-10% cobalt, which improves heat resistance.
  • Hardness: Can reach 67-70 HRC after heat treatment.

• PVD Coating:

  • Increases tool life by reducing wear and friction.
  • Provides a low coefficient of friction, improving chip evacuation.
  • Enhances surface hardness, making the punch resistant to abrasion.
  • Common PVD coatings include TiN (Titanium Nitride), TiAlN (Titanium Aluminum Nitride), and AlCrN (Aluminum Chromium Nitride)specific coating type depends on application requirements.

Applications:

• Used in cold forging and precision machining.
• Suitable for high-strength materials, stainless steel, and other alloys.
• Common in automotive, aerospace, and industrial manufacturing.
