Cold heading machine shear
The high-frequency welding process simultaneously quenches the steel material of the blade, enhancing its hardness. The Tungsten‑Carbide (carbide) used in the welding is of grade KG6 with a hardness of HRA90 or higher, possessing strong wear resistance and impact resistance. It can withstand high-frequency, high-intensity shearing operations, with a service life far exceeding that of ordinary tungsten steel, significantly reducing your component replacement costs and downtime for maintenance.
- High-hardness Tungsten‑Carbide ensures a smoother cut
- With a hardness of 91 degrees, it is more wear-resistant
- High-frequency welding, stronger
- Mass production results in more favorable prices

Every cold header starts with a clean cut. Our cold heading cut-off knives are manufactured from high-hardness tungsten carbide and resist wear and oval distortion even under high-volume continuous production.
Cut-off Knives and Thread Die Tooling
The scissor blade is made of high-frequency welded tungsten carbide, and the blade is quenched simultaneously through high-frequency induction, which enhances its hardness and toughness.
On multi-station cold heading machines, the cut-off scissors, wire feed dies (quill dies) and die shells are uniformly made of H13 mould steel hardened to HRC 46–48, while the tungsten carbide inlay reaches HRA 91 for maximum wear resistance — a matched fastener forming tooling set that keeps blank quality square, clean and burr-free.
Cut-off knives, quill dies and carbide die inserts (carbide nibs) are available for 104S–166L headers. Send your header model for a fast quote.
