DAYTON XCDP Coated Ball Lock Regular Punches - Light Duty, Metric

These light-duty ball lock regular punches are used in injection mold tooling where repeatable locating and efficient part ejection depend on stable punch retention. The ball-lock profile helps maintain consistent positioning under cyclic press loads, which is especially valuable when ejector stroke and contact force vary across production.

Common scenarios include automotive connector and bracket molds, where metric tooling benefits from quick, reliable punch seating and predictable release for thin-walled parts. They are also suited for consumer and industrial housings that require controlled ejector action to prevent cosmetic marks.

For general die work and light stamping/forming, the combination of the ball-lock geometry and DAYTON XCDP surface coating supports longer service life in wear-prone contact zones. Choose the XCDP-coated variant when abrasion from repeated motion and ejection contact is a primary driver for downtime, while keeping performance aligned with light-duty requirements.

• Ball-lock geometry for secure retention and repeatable ejection
• XCDP coating to enhance wear resistance at the punch surface
• Metric shank diameter compatibility for standard tooling systems

This series is available in two material options: M2 and PS4. M2 is a high-speed steel commonly selected for its balanced hardness and wear resistance in tooling applications, supporting good toughness for repetitive cycles. PS4 is offered as an alternative steel grade when customers prioritize cost/performance for light-duty production.

• M2: Typically selected for higher wear resistance where repeated sliding/contact is expected.
• PS4: A practical choice for light-duty work with suitable durability for efficient ejection.

The DAYTON XCDP coating further improves surface wear behavior by reducing abrasion and friction at the working contact area. Exact heat treatment state (e.g., quenched & tempered, nitrided) and measured hardness in HRC are not specified in the provided data, so engineers should confirm hardness targets for their specific tip shape and load conditions.

Select the punch based on the mold ejector/core interface first, then confirm tip geometry and working dimensions. The D (shank diameter) range is 6 ~ 38 mm; match this to the mating hole/guide diameter in your tooling to ensure proper ball-lock seating and stability.

Next, choose the L (length) range that meets your cavity/core stack-up requirements: available options include 63 ~ 100 mm, 71 ~ 100 mm, and 80 ~ 100 mm. The L1 (point length) options are 10 ~ 13 mm, 10 ~ 19 mm, 13 ~ 25 mm, and 19 ~ 30 mm; use L1 to control the effective protrusion and contact timing during ejection.

• Choose D to fit the punch seat/guide (ball-lock retention depends on correct sizing).
• Choose L for stack height clearance and safe stroke limits.
• Choose L1 for the required protrusion/contact length.

Tip shape is configurable (H, J, K, L, N, O, R, V, X, Y, Z), so select the profile that matches part geometry and ejector mark risk. Tolerance values are not provided; verify mating dimensions and fit by referencing your tool’s drawings and acceptable clearance for ball-lock engagement.
