M2 Steel Ball Lock Regular Punches - Heavy Duty X-Shaped Tip

Ball lock regular punches are used in injection-mold tooling primarily as die-safe forming inserts for upstream metalwork and as precision components inside progressive/transfer systems that feed molded part blanks. The X-shaped tip variant stabilizes tip-to-die contact, which helps maintain consistent blanking force and reduces separation variability during high-cycle runs.

• Automotive connector and terminal fabrication: CRN-coated, M2-based punches support wear control when stamping sheet metal features that later become components or inserts for molded assemblies.
• Electrical housing and bracket stamping: the heavy-duty punch geometry supports reliable part ejection and controlled blanking for repeatable tolerances across typical press setups.
• Industrial precision stamping: multiple tip shapes allow matching to die clearance and material thickness; the X-tip is suited when tool stability and consistent cut quality are priorities.

With M2 steel and the X-tip contact design, this configuration is particularly suited for long production cycles where cutting edge stability and controlled wear are required.

This punch is available in M2 steel or PS4. M2 steel is a high-speed steel grade typically associated with improved red-hardness and cutting wear performance versus many general-purpose tool steels, making it suitable for heavy-duty blanking where edge retention matters.

• Heat treatment (state): the product description specifies the M2 build is quenched for durable cutting performance and repeatable tool behavior (quench state provided in the supplied description).
• Wear resistance vs. toughness: the CRN-coated surfaces (noted in the description) enhance wear resistance, which generally improves tool life but can require careful alignment to avoid edge chipping under severe shock loads.
• Coating effect: CRN-coated tooling helps control wear during production cycles, supporting stable punching geometry over time.

Compared with PS4, M2 is selected when higher wear performance and cutting edge stability are needed; PS4 may be considered as an alternative material option depending on supplier/program compatibility.

Select the punch size by matching the shank diameter (D), overall length (L), and point length (L1) to your die/tool block cavity or core location depth. This series supports D = 10–40 mm and L = 63–125 mm (with additional L variants listed), plus L1 = 10–19 mm, 13–25 mm, or 19–30 mm depending on the chosen configuration.

• Tip engagement: confirm the point length (L1) provides the required penetration into the die opening while maintaining safe clearance for the punch stroke.
• Tool mounting: use the D range to match the punch holder bore and guide fit in your press or die set.
• Blanking geometry: verify P (1.5–12 mm) and W (1.5–14 mm) against the die land and cutting edge overlap requirements for the target sheet/form material.
• Radial feature: keep the specified R = 0.2 mm consistent with your die corner radius requirements.

Tolerances and final fit are governed by your punch holder and die set dimensions; when using different tip shapes, re-check clearance to ensure stable contact and consistent separation.
