In the cold heading fastener industry, punches are typically made from M42 or M2 materials. However, when producing ultra-high hardness stainless steel fasteners, tungsten carbide punches become essential.
However, with the continuous rise in tungsten carbide prices, the cost of solid carbide punches has become increasingly difficult to bear. Therefore, we currently recommend customers consider using brazed punches.
A brazed punch features a tungsten carbide tip combined with a standard high-speed steel (HSS) body. Under current market conditions, this design offers an excellent balance—maintaining performance while significantly reducing cost.
- Composite Structure Design: Carbide tip for high hardness, combined with an HSS (High-Speed Steel) shank for strength and toughness
- Cost-Effective Solution: Reduces carbide usage amid rising raw material costs, lowering overall production expenses
- Excellent Wear Resistance: Carbide working area ensures superior hardness and long-term dimensional stability
- Long Service Life: Comparable lifespan to solid carbide punches, with better cost-performance ratio
- Improved Impact Resistance: HSS shank enhances toughness and minimizes the risk of breakage
- Suitable for Heavy-Duty Applications: Ideal for cold heading, forming, and other high-load operations
As for service life, in theory, as long as the brazing process is properly executed, the lifespan should be comparable to that of a solid carbide punch. If you are interested, feel free to contact us for more information about tungsten carbide brazed punches.
