Ball Lock Regular Punches Heavy Duty M2 Steel

This heavy-duty ball lock punch blank is used in injection and press tooling to achieve stable part ejection in metric progressive and transfer mold setups. The ball lock geometry helps ensure the punch stays securely retained in the holder during repeated cycling, reducing the risk of ejection inconsistency.

• Automotive and electrical connector tooling: where tight repeatability and frequent press cycles demand consistent punch travel and wear resistance at the working tip.
• Appliance and housings (small metal-to-plastic insert or post-form operations): the heavy-duty construction supports reliable ejection while handling higher contact loads.
• General production mold components: suitable when you need metric sizing options and controlled point geometry to match cavity/core feature depths.

The variant’s M2 steel base and XCDP coating combination is well suited for long service intervals by improving surface wear behavior under abrasive tool steel contact.

The primary option is M2 steel, a high-speed tool steel chosen for its strong wear resistance in die and punch applications. In this configuration, the working surfaces are protected with an XCDP coating, which is intended to reduce abrasive wear and maintain consistent ejection performance over time.

A second material option (PS4) is available for designers who want an alternative steel choice depending on performance balance and availability. Compared with M2’s high wear capability, material selection should consider the required toughness and expected cycle load; higher wear capability can come with different toughness trade-offs, so matching to the press intensity is important.

• Heat treatment state: supplied as a punch blank ready for toolmaker finishing; follow Axiom’s shop procedures for final sharpening/conditioning to your holder tolerance requirements.
• Hardness (HRC): not specified in the provided data; confirm hardness at receipt or through incoming inspection documentation.

For best results, plan grinding and polishing with respect to the coated surface to avoid damaging the coating integrity.

Select the punch blank dimensions by matching the shank diameter (D), point length (L1), and overall length (L) to your mold holder pocket depth and the cavity/core engagement requirement.

• Shank diameter (D): choose 10 ~ 40 mm to fit the holder bore and ball lock interface without excessive clearance.
• Point length (L1): select from 10 ～ 19 mm, 13 ～ 25 mm, or 19 ～ 30 mm based on how far the working point must penetrate to actuate ejection.
• Overall length (L): pick from 63 ～ 125 mm, 71 ～ 125 mm, or 80 ～ 125 mm to ensure correct stroke geometry and safe retention within the holder.

To refine fit, align the P and W dimensions (1.5 ~ 12 mm and 1.5 ~ 14 mm) with the feature envelope of the mating punch/clearance condition. Tip shape is variable (H, J, K, L, N, O, R, V, X, Y, Z), so confirm the selected geometry matches the ejection surface profile. Tolerances are not provided; verify fit against your holder’s drawing and perform trial assembly for clearance before production.
