Headed Die Buttons ISO 8977 Type B

Precision punching operations demand components that deliver consistent performance, durability, and adherence to international standards. Our range of high-performance Cutting Die Buttons ISO 8977 is engineered for exactly this purpose. Specifically, the Shoulder Type Die Buttons, conforming to the ISO 8977 Type B specification, represent a pinnacle of design for applications requiring exceptional stability. Featuring a robust headed shoulder, these buttons provide superior lateral support within the die plate, significantly reducing deflection under load and extending tool life. They are the ideal choice for demanding blanking, piercing, and forming processes across various industries, including automotive, electronics, and appliance manufacturing.


The Headed Die Buttons ISO 8977 Type B is distinguished by its specific geometric design, which includes a precise shoulder height and diameter to ensure a perfect press-fit into standard die plates. This design minimizes the risk of button movement or rotation during high-speed, high-tonnage operations. Manufactured from premium-grade tool steels and subjected to rigorous heat treatment processes, each Headed Die Buttons ISO 8977 Type B offers excellent wear resistance and toughness, capable of withstanding the abrasive forces encountered in processing a wide array of materials from soft non-ferrous metals to high-strength steels.

Key Features & Specifications

  • Manufactured to ISO 8977 Type B dimensional standards for global compatibility.
  • Headed shoulder design for maximum stability and resistance to lateral forces.
  • Constructed from high-grade alloy tool steel (e.g., D2, A2) for optimal performance.
  • Precision ground to ultra-tight tolerances for consistent hole size and finish.
  • Available in a comprehensive range of standard diameters and lengths.
  • Optional surface treatments and coatings (e.g., TiN, TiCN) for enhanced wear resistance.
