Ball Lock Regular Punches XCN Coating

These light-duty ball-lock punches are used in stamping and forming die sets where consistent retention and ejection repeatability are required across long production runs. The ball-lock retention design helps maintain stable punch positioning so the part consistently releases during cycle operation, reducing misalignment and debris buildup.

• Automotive and appliance stamping: Select the appropriate point shape (H, J, K, L, N, O, R, V, X, Y, Z) to match the die contact geometry and improve ejection reliability for thin to moderate metal sections.
• General forming and pilot/point operations: Use the XCN-coated variant to improve surface protection at the punch face and shank, supporting steadier operation through routine maintenance intervals.
• Die maintenance and tool refurbishment: Metric-compatible sizing options (shank diameter and length ranges) make it practical to replace punches in existing tooling while keeping retention performance consistent.

Overall, the XCN coating and regular light-duty construction make this variant well-suited for applications prioritizing reliable ejection with stable tool positioning.

This punch series is available in two specified materials: M2 and PS4. M2 corresponds to a high-speed steel approach (commonly treated as an M2/AISI-type grade family) selected for balanced hardness and wear resistance under repetitive punching and forming loads. PS4 is provided as an alternative steel option for tool makers who want a different performance balance for their forming duty.

• Wear resistance vs. toughness trade-off: Materials selected for higher surface durability typically support longer punch life, while toughness must remain sufficient to resist chipping at the point during repeated impacts.
• Coating interaction: The listed XCN coating is intended to enhance surface protection, helping reduce friction and abrasive wear at the working surfaces.
• Heat treatment state: The dataset does not specify exact hardness (HRC) or heat treatment steps (e.g., quenched & tempered, nitrided). Confirm hardness and treatment requirements with your tooling specs prior to final selection.

Correct selection should start with matching the shank diameter D (6 ~ 38 mm) and the overall length L ranges available in your configuration. Then confirm the point length L1 and tip geometry so the punch works through the die stack exactly as intended for your stamping or forming operation.

• Match retention and guidance: Choose a punch with D in the 6 ~ 38 mm range that fits your guide openings and ball-lock retention features in the die set.
• Set working engagement: Select L1 according to your required point reach (available bands: 10–13, 10–19, 13–25, 19–30 mm), then verify the overall L within available ranges (63–100, 71–100, or 80–100 mm depending on the offered option).
• Confirm point contact dimensions: Use P (1.4 ~ 12 mm), W (1.4 ~ 14 mm), and R (0.2 ~ 0.2 mm) to align the tip profile with the die cavity/core contact behavior.
• Tolerances/fit: The dataset does not provide tolerance values; use your die maker’s standard clearances for punch guidance and retention, and validate fit on a gauge set before full production.

Tip shape and XCN coating help compatibility across configurations, but dimensional matching to cavity/core stack height and guidance geometry remains the key selection step.
