JIS Standard Steel Extended Range Punches X-Tip

Extended reach punches with an X-tip option are used in metric die sets where punch penetration depth demands stable cutting geometry over a longer reach. In progressive tooling, they help maintain consistent shearing action as the material advances through multiple stations, which is especially important when strip layouts create longer travel paths.

• Automotive and appliance connector stamping: Suitable for repeatable hole/pierce operations in deeper die stations where standard-length punches may deflect or lose edge consistency.
• Battery, terminal, and contact fabrication: The X-shaped tip selection supports stable shearing at production conditions, improving edge reliability during high-cycle runs.
• General industrial progressive dies: The steel punch body is intended for robust wear behavior, aligning with tight die assembly practices and standard tool setups.

With fixed point length L1 = 25–30 mm and overall length L = 63–100 mm, this configuration is a practical choice for die makers balancing reach and punch-edge stability.

For JIS standard extended-range punches, the product is specified as a steel construction intended to support reliable punching performance. The key performance driver for punches is balancing wear resistance (to hold the edge during repeated shearing) with toughness (to resist chipping or edge breakdown under load).

• Wear behavior: Steel is selected for stable tool life in punching applications, where abrasion and edge deformation occur cycle after cycle.
• Toughness trade-off: Higher hardness improves edge wear but can reduce impact toughness; the final performance depends on the heat treatment applied to the punch steel.
• Heat treatment state: The available data specifies steel construction but does not provide a named grade, hardness (HRC), or exact heat treatment (e.g., quenched & tempered, nitrided).

If you need a specific JIS steel grade equivalent (e.g., SKD61/H13 or similar) or target hardness, confirm the steel specification with Axiom Molds for your intended metal type and press tonnage.

Select dimensions by matching reach requirements of the die station and the material clearance stack-up. This punch series provides a fixed point length L1 = 25–30 mm, while overall length L = 63–100 mm supports extended reach in deeper layouts.

• Choose shank diameter (D): Pick from D = 40, 45, 50, 56, 63 mm to fit your punch holder and guide bushings for the die set.
• Match plan/profile dimensions: Use the allowed ranges for P = 20–39.95, 25–44.95, 30–49.95, 35–55.95, 40–62.95 mm and W = 8–39.95, 9–44.95, 10–49.95, 11–55.95, 12–62.95 mm according to the holder geometry and X-tip form requirements.
• Tip geometry tuning: Set the R dimension within 0.2–19.975, 0.2–22.475, 0.2–24.975, 0.2–27.975, 0.2–31.475 mm to align with the intended edge radius and cutting stability.

The tip shape is configurable via H, J, K, N, O, R, V, X, Y, Z, including an X-tip option for stable punching action. The provided specification data does not include tolerance values; confirm fit class/tolerance with your tooling drawing requirements.
