M2 Steel Ball Lock Pilot Punches - Tapered Tip, Heavy Duty,

These tapered-tip ball-lock pilot punches are used to control the start of the shot and ensure accurate registration between matched tooling halves. In automotive connector and terminal mold operations, the tapered entry geometry promotes smooth pilot engagement, reducing the risk of misalignment during high-cycle insert handling and forming.

For consumer electronics enclosures and housings, the heavy-duty inch construction supports stable location while parts are being coined, trimmed, or overmolded. The ball-lock locating interface helps maintain repeatable positioning under load, which is critical for maintaining shut height consistency and feature alignment.

Why this variant fits: the M2 steel base provides durable hardness for dimensional stability, while the XNM coating improves wear resistance at the pilot contact area—supporting long production runs where frequent ejector/pilot cycling can accelerate wear.

• Automotive connector/terminal molds: tapered tip for reliable lock-in and alignment at fast cycle rates
• Electronics housings: stable ball-lock registration for consistent feature placement
• General die/mold assembly applications: heavy-duty inch pilot punches for robust locating under repeated engagement

This product is offered in M2 steel (also listed as an available option: PS4). M2 is a high-speed steel commonly selected for tools requiring high hardness and good wear resistance at the contact interface, supporting consistent locating behavior over repeated pilot engagement.

Heat treatment is typically specified as a hardened condition for precision pilot use: M2 is generally supplied in a quenched and tempered state to balance hardness and toughness. Expect a practical trade-off: higher hardness increases wear resistance on the tapered and ball-lock contact surfaces, while excessive hardness reduction would lower service life under friction and micro-impact.

• M2 steel: high hardness for dimensional stability and wear resistance; balanced toughness after quench & temper
• XNM coating: targeted reduction in wear at the locating region
• PS4 (if selected): alternative material option within the listed variants; confirm hardness and heat-treatment state with your drawing for end-use requirements

Hardness (HRC): not provided in the supplied metadata; request the material cert/datasheet for the exact HRC target for your selected option.

Correct sizing is determined by matching the shank diameter D and the selected point/pilot length ranges to your mold core/cavity receiving features. This product lists D (shank dia.) from 37 to 125 in and point/pilot length options in coded inch ranges: 250–600, 250–700, 275–700, and 300–700.

Use the P dimension range (0.083–0.999) to align the ball-lock profile depth/positioning to your mating parts. If you are working from a drawing, select the variant whose standard point length & L (or the coded B/C/*or* D point-length configurations listed in your spec) matches the required pilot penetration and clearance to avoid interference.

• D (shank dia.): choose within 37–125 to fit the guide/pilot bore system
• Point length: choose within one of 250–600 / 250–700 / 275–700 / 300–700 based on required engagement depth
• P: ensure 0.083–0.999 corresponds to your ball-lock positioning geometry

Tolerance & fit: exact tolerances are not provided in the metadata; for pilot punches, confirm the fit class/clearance with your mating bore and ball-lock receiver design to prevent binding during shut-off.
