About HEXAGONAL FORGING PUNCH DIA 11.90/ HEX A/F 8.10 x 90MM WITH PVD TIN COATING HSS M42

Hexagonal Forging Punch 11.90 / Hex A/F 8.10 90mm with PVD TiN Coating, HSS M42

1. Overview:

This Hexagonal Forging Punch is engineered from HSS M42 (High-Speed Steel, M42 Grade), which is ideal for forging, punching, and forming high-strength materials. The tool features a PVD TiN (Titanium Nitride) coating, enhancing its wear resistance, heat resistance, and tool life. The punch is specifically designed for applications that require hexagonal punch profiles for nut and bolt production, automotive, and aerospace industries.

3. Material & Coating Details

• HSS M42:

  • Contains 8-10% cobalt, providing high red-hardness and excellent toughness.
  • Capable of enduring high-speed punching and extreme pressure in metal-forming applications.
  • Suited for abrasive materials and high-strength alloys.
  • Maintains its hardness at high temperatures, making it ideal for cold and warm forging processes.

• PVD TiN Coating:

  • The PVD TiN coating provides a hard, wear-resistant surface that enhances tool longevity.
  • Reduces friction, preventing material build-up, ensuring smoother operation.
  • Increases the punch's thermal stability, allowing it to endure high-speed, high-heat forming without loss of performance.
  • Ideal for highly abrasive applications and continuous high-load operations.

4. Applications

Hexagonal Nut & Bolt Production Primarily used in forging hexagonal shapes for bolts, nuts, and similar fasteners.
Automotive & Aerospace Manufacturing Ideal for precision forming in parts that require a hexagonal shape.
Metal Forming Used in cold and warm forging processes to create hexagonal profiles in various metals and alloys.
Heavy-Duty Industrial Forging Suitable for continuous use in high-speed production environments with little tool degradation.

5. Benefits

• Enhanced Durability: The PVD TiN coating provides extended tool life by increasing wear resistance.
• High Precision: The hexagonal punch profile ensures accurate and uniform nut/bolt formation.
• Superior Heat & Wear Resistance: Withstands high temperatures and abrasive materials without performance loss.
• Low Friction: Reduces tool wear and prevents material from sticking, ensuring smooth operation and efficiency.
• Consistent Performance: Suitable for high-volume, high-speed forging without frequent tool changes.

6. Comparable Alternatives

Alternative	Key Benefits
TiN Coating (Titanium Nitride)	Provides wear resistance but has lower heat tolerance than PVD TiN.
TiAlN Coating (Titanium Aluminum Nitride)	Superior for extreme temperatures but with slightly less wear resistance than TiN.
Carbide Punches	More wear-resistant but less tough and more prone to breakage under impact.
Uncoated HSS M42	Same base material but without the friction-reducing benefits of TiN coating.
