Metric Tapered Tip Light Duty Ball Lock Pilot Punches

These light-duty ball lock pilot punches with a tapered tip are used in injection and compression die assemblies to accurately locate components before forming or ejection. The ball-lock retention helps maintain stable punch-to-block guidance, reducing drift during repeated press cycles.

Common scenarios include:

• Automotive and industrial die sets: used as pilot members to align strip or stacked tooling where metric die components require repeatable positioning.
• Die assemblies for ejection/blanking: the tapered nose improves entry and pilot engagement, supporting smooth alignment at start-up and minimizing edge contact.
• Precision die build-ups and repairs: the broad D shank dia. range enables tool designers to match different locating post diameters without changing the core pilot concept.

This variant’s metric compatibility and tapered geometry make it well-suited for centering and consistent engagement while remaining appropriate for lighter-duty locating applications.

The provided specifications describe the geometry and sizing only; no steel grade, hardness (HRC), or heat-treatment state is included in the input data. As a result, the material properties and any specific heat treatment (e.g., quenched & tempered, nitriding) cannot be stated reliably for this series based on the supplied information.

What can be confirmed from the datasheet inputs is that the product is engineered for stable retention and guidance via the ball-lock design, which primarily impacts functional fit and wear behavior at the contact interface during alignment and ejection.

• Material-related selection note: when specifying for your die environment (shock loading, abrasive wear, corrosion), confirm the steel grade and heat treatment from your official manufacturer datasheet or request Axiom Molds’ material certs.
• Trade-offs: harder tool steels typically improve wear resistance but may reduce toughness; the final choice should align with load level and expected cycle count.

Select the pilot punch size to match the locating needs of your die cavity/core interface. Use the D (shank dia.) range of 10 ~ 38 mm to fit the corresponding pilot receiving feature in the die set. Choose L1 (point length) from the available options (19 ~ 72, 19 ~ 102, 25 ~ 112, 30 ~ 112 mm) to control how deeply the tapered tip engages during pilot entry.

Next, verify the overall L (length) per your mounting and stack-up constraints: 71 ~ 110, 71 ~ 140, 71 ~ 150, or 80 ~ 150 mm (depending on the selected variant).

• P (dimension) is specified as 1.45 ~ 30 mm; match this to the functional requirement tied to your lock/retention geometry.
• Tolerance/fit: for reliable ball-lock engagement, ensure your receiving bore/seat dimensions are controlled so the pilot can center on entry and lock consistently without excessive clearance.
• Configurable vs fixed: D, L1, L, and P are variable within the given ranges; treat them as your configured sizing parameters, while the ball-lock + tapered tip architecture remains fixed by the series concept.
