Metric XVP Coated Ball Lock Pilot Punches - Tapered Tip

Q: How do I choose the correct point length (L1) and overall length (L) for my die clearance?

Select L1 (point length) from 19–72, 19–102, 25–112, or 30–112 mm so the tapered tip reaches the alignment region during the full cycle. Then verify L (overall length) fits with your die height and stop positions using 71–110, 71–140, 71–150, or 80–150 mm . This prevents interference and maintains engagement stability.

Q: What does the XVP coating contribute to pilot performance in long runs?

The product description indicates that XVP coating is intended to improve wear resistance . In practice, that supports maintaining functional geometry and centering performance over extended production. For exact wear expectations, correlate coating performance with your stroke frequency and material/forming load.

Q: How do I ensure the pilot lock fit when selecting shank diameter (D) and P dimension?

Match D from 10–38 mm to the mating pilot locating feature diameter to prevent looseness (loss of centering) or binding (excess friction). Then set the feature offset using P = 1.45–30 mm per your die design geometry. If you have tight fit requirements, confirm tolerances with your drawings since tolerance values are not provided here.

Q: Is this series intended for metric light duty applications only?

Yes—this variant is described as for light duty metric punch applications with tapered-tip geometry and XVP coating. It is recommended for progressive dies and general metal stamping pilot locating. If your application involves higher duty loads, you should verify whether a different duty/coating configuration is required.

Product Guide

🏭Application Scenarios+

These tapered-tip, XVP-coated ball lock pilot punches are used to establish precise lead-in and centering in light duty metric die sets, especially where repeatable positioning improves part-to-part consistency.

Progressive metal stamping: Install in locating systems to guide strip and dies through multiple stations; the tapered tip promotes smooth entry and reduces the risk of misalignment during high cycling.
Automotive and appliance bracket tooling: When using standard metric punch layouts, the metric light duty sizing supports stable pilot fit, helping maintain consistent hole location over long production runs.
General die tryout and rework: During setup changes, the ball-lock principle helps maintain reliable pilot performance with fewer centering variations; the XVP coating is suited for improved wear behavior in continuous use.

Select the appropriate shank diameter and point length from the provided ranges to match your core/cavity pilot locating requirements.

🔧Material & Process Details+

The provided product data specifies performance features (tapered tip geometry and XVP coating) but does not list a specific steel grade or measured hardness (HRC). Therefore, the material grade, heat-treatment state (e.g., quenched & tempered or nitrided), and exact hardness cannot be confirmed from the available inputs.

XVP coating: Designed to enhance wear resistance for long production runs, supporting stable pilot centering as tool surfaces experience repeated sliding/impact during feed and positioning.
Tapered tip: Improves lead-in and alignment, which reduces localized stress and helps preserve functional geometry.

If you need confirmation of steel grade and heat treatment for your process window, request the specific material certificate for series code 250301828426.

📐Sizing & Selection Guide+

Correct dimension matching is critical because pilot punches directly control die-to-strip centering. Use the available ranges to select a shank size that fits your locating bore and provides stable guidance throughout the stroke.

Shank diameter (D): Choose from 10–38 mm based on the mating ball-lock pilot pocket or guide feature diameter.
Point length (L1): Select from 19–72, 19–102, 25–112, or 30–112 mm to ensure the tapered tip reaches the intended alignment zone.
Total length (L): Confirm clearance and engagement with options 71–110, 71–140, 71–150, or 80–150 mm.
P dimension: Match P = 1.45–30 mm to the required locating offset/feature geometry for your die layout.

Because tolerance/fit values are not provided, verify fit by checking the mating feature dimensions in your die design drawings and ensure adequate clearance to prevent binding while maintaining positional control.

Frequently Asked Questions

Which tapered-tip geometry is best for stable centering in progressive dies?+

For progressive metal stamping where centering consistency matters, select the tapered tip version paired with the correct metric shank diameter range (D = 10–38 mm). The tapered lead-in helps guide alignment into the locating zone smoothly. Choose an L1 (point length) option that allows the tip to engage sufficiently without bottoming, using the listed L1 ranges.

How do I choose the correct point length (L1) and overall length (L) for my die clearance?+

Select L1 (point length) from 19–72, 19–102, 25–112, or 30–112 mm so the tapered tip reaches the alignment region during the full cycle. Then verify L (overall length) fits with your die height and stop positions using 71–110, 71–140, 71–150, or 80–150 mm. This prevents interference and maintains engagement stability.
