Metric Ball Lock Ejector Punches Heavy Duty Tip O

These heavy-duty ball lock ejector punches are used inside metric die sets where consistent point retention and stable ejection are critical. The Tip O point geometry supports reliable engagement of the ball lock retention system, helping maintain performance over repeat cycles.

• Automotive blanking and forming: In progressive tooling, the larger point contact helps resist point wobble and improves ejection repeatability when parts are cycled at high rhythm.
• Appliance and bracket manufacturing: For thicker stock blanking, heavy-duty construction supports efficient ejection during forming operations where friction and wear increase.
• General die-set tooling: The variant’s metric shank diameter range (D = 13–40 mm) enables compatibility with common metric punch and die components, supporting correct fit within the guide and stripper interfaces.

Choose the Tip O variant when you need stable point engagement and dependable ejection behavior for blanking, forming, and progressive die applications.

The provided product data specifies Tip shape, geometry, and dimensional ranges, but does not list the steel grade or heat-treatment condition. For that reason, hardness (e.g., HRC), wear resistance levels, and toughness trade-offs cannot be stated from the input alone.

In ball lock ejector punch applications, the steel selection typically targets a balance of wear resistance at the point and toughness in the shank to resist bending and impact from repeated ejection cycles. Heat treatment states commonly used for this class of tooling include quenched & tempered for toughness or nitriding for enhanced surface wear resistance, but the exact condition for this DAYTON series is not provided here.

• If you need nitrided vs. quenched-and-tempered confirmation, request the specific material/heat-treatment certificate for series code 250000001659.

Variant selection should be aligned with your expected wear mechanism and cycle rate once the exact steel spec is confirmed.

Select dimensions to match your ejector system’s guide and ball lock retention requirements, then verify overall stroke accommodation. This heavy-duty metric version uses fixed lengths and a controlled point length, simplifying cavity/core integration.

• Shank diameter (D): Choose from 13, 16, 20, 25, 32, 40 mm to match the punch guide bore and die set interface.
• Point length (L1): Fixed range 19–30 mm; confirm this provides sufficient point penetration and clearance for the die opening.
• Overall length (L): Fixed range 80–100 mm; ensure the ejector stack height allows full stroke without bottoming.
• P dimension: Select within the available ranges (e.g., 13.1–32 mm, 16.1–38 mm, 20.1–40 mm, 25.1–44 mm, 32.1–50 mm, 40.1–56 mm) for the specific D you select.
• W and R: Confirm W = 1.57–34.73 mm and R = 0.2–16 up to 0.2–28 mm correspond to your required point profile and lead-in geometry.

Because tolerance values are not included in the provided data, verify fit by referencing your die set drawing tolerances for ejector guides and ball lock receptacles.
