Tungsten Carbide Wear Part Hard Metal Punch for Industrial Use
This series of tungsten carbide punch pins is specifically engineered for Group's BM-B-2 end cover mold, designed for precise inner diameter punching applications.
Purpose and Features
These custom tungsten carbide punch pins meet Group's stringent chemical, physical management, and ROHS EU standards. The material properties ensure exceptional performance in demanding industrial environments.
Dimensional Specifications
Primary Dimensions:
• Φ47.03 (±0.002) * Φ47 * Φ40 * Φ3 * M12-25 * 94.40
• Φ47.025 (±0.002) * Φ47 * Φ40 * Φ3 * M12-25 * 94.40
Compared to conventional hard alloy punch pins, these tungsten carbide versions feature larger outer diameter dimensions with tight tolerance requirements of ±0.002. The design includes radius transitions of R0.50 and R1.00 between diameters, an M12 thread at the bottom with 25mm depth, and a Φ3 air hole running 50.9mm from top to side. Total length is 94.4mm.
