HEXAGONAL FORGING PUNCH DIA 7.50/ HEX A/F 6.10 x 85MM WITH PVD TIN COATING HSS M42

Product Description

Hexagonal Forging Punch 7.50 / Hex A/F 6.10 85mm with PVD TiN Coating, HSS M42

1. Overview:

This Hexagonal Forging Punch is a high-performance tool made from HSS M42 (High-Speed Steel, M42 Grade), offering superior hardness, wear resistance, and durability in metal forming applications. It features a PVD TiN (Titanium Nitride) coating, which provides enhanced wear resistance, thermal stability, and extended tool life. Designed specifically for high-speed punching and forging, this tool is ideal for precision forming of hexagonal profiles, commonly used in nut and bolt production, aerospace, and automotive industries.

3. Material & Coating Details

• HSS M42:

  • Contains 8-10% cobalt, providing high red-hardness and exceptional toughness.
  • Capable of withstanding high-pressure punching and forming operations.
  • Excellent for use with abrasive materials and high-strength alloys.
  • Maintains hardness at elevated temperatures, making it ideal for cold and warm forging.

• PVD TiN Coating:

  • Titanium Nitride (TiN) provides a hard, wear-resistant surface that enhances tool longevity.
  • Reduces friction, preventing material build-up and increasing tool life.
  • Increases thermal stability, enabling the punch to endure high-speed, high-heat forging without performance degradation.
  • Ideal for high-strength alloys, stainless steel, and other tough materials.

6. Comparable Alternatives

Alternative	Key Benefits
TiN Coating (Titanium Nitride)	Offers good wear resistance but has lower heat tolerance compared to PVD TiN.
TiAlN Coating (Titanium Aluminum Nitride)	Excellent for extreme temperatures but with slightly lower wear resistance than TiN.
DLC Coating (Diamond-Like Carbon)	Superior friction properties but with lower thermal stability than TiN coatings.
Uncoated HSS M42	Same material base but lacks heat and wear resistance offered by the TiN coating.
