Tungsten Carbide Shear-Cut Punch with 100% Virgin Tungsten Carbide HRA89-HRA92.9 Hardness and YG6/YG8/YG10X/YG20C Alloy Specification

Product Overview
The Tungsten Carbide Shear-Cut Punch is an industrial-grade cutting tool engineered for high-precision blanking and piercing operations. Manufactured from ultra-fine grain tungsten carbide, it features an optimized shear-angle geometry that enables clean material separation while significantly reducing punching force and tool wear. Ideal for processing challenging materials including stainless steel, silicon steel, and high-strength alloys.

Technical Advantages

1. Shear-Angle Design
   • Reduces peak punching force by 30-40% compared to standard punches
   • Minimizes burr formation through controlled material fracture
   • Extends die life by lowering impact stress on tooling components
2. Premium Material Performance
   • Core hardness: 90-92 HRA
   • Transverse rupture strength: ≥3500 MPa
   • Exceptional edge retention maintains cutting sharpness 8-10x longer than HSS
3. Precision Engineering
   • Concentricity: ≤0.003mm
   • Surface finish: Ra ≤ 0.1μm (working surfaces)
   • Angular tolerance: ±0.1°
