119 Hole Punch Pins for Hex Nut | Cold Heading Punches

#5 PUNCH PIN 119 Hole Piercing Punch for Nut Former

These 119 punch pins engineered for demanding multi-station nut formers and cold heading machines, these punch pins deliver outstanding red hardness, impact toughness, and micro-wear resistance under high-frequency continuous forging cycles.

Key Features

• Premium High-Speed Steel (HSS) Grades – Made from premium HSS (M2 / M35 / M42), designed for the final station of the DIN934 M6/M8/M10/M12/M16 hex nut forming.
• Precision Profile – Sub-micron CNC cylindrical grinding ensures exceptional concentricity, straightness, and mirror-finished working surfaces to minimize friction and prevent galling.
• Superior Impact & Fatigue Resistance – Balanced core toughness absorbs severe cyclical shock loads, drastically cutting down on pin snapping, bending, and downtime.
• Optional PVD Surface Coatings – Available with wear-resistant TiN (gold) or TiCN (gray/black) coatings to extend tool life in severe high-speed production environments.
