YL10.2 Ultra-Fine Grain (0.6-0.8μm) Tungsten Carbide Punch with HRA 91.5+ Hardness and TRS ≥3800 MPa for Cold Heading

In cold heading and precision forming operations, the pressing punch is the critical tool that transforms raw material into finished fasteners, components, and precision parts. When that punch wears prematurely or fails to maintain its geometry, the result is inconsistent part quality, increased scrap rates, and costly production downtime.

Our YL10.2 Tungsten Carbide T-Head Pressing Punch is engineered specifically for demanding cold heading and forming applications. Manufactured from premium YL10.2 cemented carbide—an ultra-fine grain (0.6-0.8μm) tungsten carbide grade renowned for its exceptional combination of high hardness, outstanding wear resistance, and superior transverse rupture strength—this punch delivers the durability and precision required for high-volume fastener manufacturing and precision forming operations.

The T-head pressing punch features a distinctive T-shaped profile designed for specific cold heading applications. Its unique geometry enables precise material displacement and part formation in multi-stage cold heading processes, where standard cylindrical punches cannot achieve the required forming characteristics or withstand the applied stresses.

YL10.2 is a high-performance tungsten-cobalt (WC-Co) cemented carbide grade consisting of approximately 89.8% tungsten carbide (WC) and 10.2% cobalt (Co) binder. Its defining characteristic is the ultra-fine grain structure (0.6-0.8μm), which delivers a unique combination of properties that makes it the preferred material for high-wear forming tools.
