High-Speed Steel Punches – High-speed steel (HSS) punches are precision stamping tools, which are known for their hardness, toughness, and wear resistance. HSS punches are widely used for various high-load and high-speed stamping applications for the automotive, aerospace, electronics, and general manufacturing industries. Our HSS punches deliver incomparable performance and durability with state-of-the-art manufacturing processes, innovative heat treatment technologies, and customizable options.
We use high quality High Speed Steels (HSS) alloy containing tungsten, molybdenum, chromium and vanadium for our HSS punches to make the toughest and most durable products available. Our HSS grades are used in specific applications:
A general-purpose HSS showing good toughness and wear resistance, being an ideal choice for moderate-load stamping dies.
Cobalt enhances HSS and gives it a better red hardness and wears resistance, therefore suitable for stamping applications in higher temperature.
Due to this high cobalt content, has the best red hardness properties, perfect for high-speed stamping, and punching in thick plate.
| Material Type | Wear Resistance | Toughness | Application |
| Hss(M2,M35,M42 etc.) | Excellent | Good | Precision stamping,high-speed cutting |
| Carbide(Tungsten Steel) | Superior | Low | Extreme wear applications,brittle under impact |
| Carbon Tool Steel | Moderate | High | General low-load stamping applications |
1. High Hardness and Wear Resistance
