Metric M2 Steel Regular Punches XNP Coating

These metric regular punches are used as replaceable wear items in precision die sets for high-frequency forming operations. The combination of M2 tool steel and a low-friction XNP coating makes them well-suited for long production runs where consistent punching force and dimensional stability matter.

• Automotive connector and terminal forming: selected tip shapes (H, J, K, L, N, O, R, V, X, Y, Z) support different hole/profile requirements while the coating helps reduce friction-related wear across repeated cycles.
• Electrical housing and bracket punch dies: regular punch geometry and controlled shank diameters (D = 4–32 mm) help align with cavity/core features, supporting repeatable part geometry during continuous output.
• General industrial metal stamping: the stable forming performance of M2 steel combined with XNP wear control supports predictable tool life when the process involves frequent starts/stops and varying material lots.

Dayton/Lamina-format part compatibility streamlines selection in standardized production tool builds.

This series is built from M2 steel, a high-speed steel grade commonly chosen for punching tools that require a balance of hardness, wear resistance, and toughness. For friction and abrasive wear control at the contacting surfaces, an XNP coating is applied to help manage running wear and improve durability under repeated cycles.

• Material options: M2 is the primary material for stable forming performance; PS is offered as an alternative where your shop’s material strategy favors a different baseline property set.
• Coating function: XNP reduces friction to slow wear mechanisms that can otherwise lead to dimensional drift.
• Heat treatment: the provided data specifies M2 steel and XNP coating; hardness and exact heat-treat parameters (e.g., quenched & tempered, nitrided) are not included in the current specifications.

When selecting between M2 and PS, base steel choice should be aligned with your press load, workpiece material abrasiveness, and expected life targets, with the XNP layer providing additional surface wear management.

Selecting the correct punch size is primarily about matching the punch tip geometry and the shank dimensions to the die set’s cavity/core requirements and guidance features.

• Choose tip shape: pick from H, J, K, L, N, O, R, V, X, Y, Z based on the required hole/profile.
• Match the shank diameter D: available in 4–32 mm. Use the die guide and stripping system’s bore size to ensure correct alignment and support.
• Verify point length L1: available in ranges 8–13, 13–19, 19–25, and 25–30 mm to control effective penetration.
• Confirm overall length L: offered as 40–100, 50–100, 56–100, and 63–100 mm depending on your tool height and holder.
• Check profile dimensions: P = 0.8–10 mm, W = 1.3–10 mm, and R = 0.2 mm to maintain the edge detail your die design expects.

Tolerance/fit values are not provided in the input data, so align selection to your die block tolerance chain and the holder’s guidance specs (especially for D).
