Ball Lock Pilot Punches Tapered Tip Heavy Duty Inch XNT DayT

These ball lock pilot punches are used in injection and stamping press tooling where repeatable part positioning depends on tight pilot control. The tapered nose promotes self-centering during die engagement, reducing the risk of misalignment in high-cycle operation.

Common scenarios include automotive connector and bracket molds, where cores/cavities must remain precisely indexed across long production runs. The tapered tip helps guide alignment, while the heavy-duty inch construction supports stable pilot behavior under repeated press cycles.

They are also suitable for medical device component housings and other precision parts that require consistent orientation for proper shutoff and feature formation. For these applications, the XNT DayTiN® coating supports durable wear resistance at the pilot interface, helping maintain positional accuracy as abrasive conditions build up.

• Tapered tip improves centering and reduces start-up misalignment
• XNT DayTiN® coating enhances abrasion/wear resistance for repetitive punching
• Heavy-duty inch pilot design supports reliable alignment in production die sets

This series is offered in M2 and PS4, enabling selection based on wear vs. toughness needs. M2 is a high-speed steel commonly associated with strong wear resistance in cutting and punch applications, while PS4 is provided as an alternate material option for tool performance requirements within this line.

The surface is specified with XNT DayTiN® coating, which is intended to improve abrasion resistance at the pilot contact area. Coatings like DayTiN® typically support longer service life by reducing wear progression during repetitive die/punch engagement.

• Hardness (HRC): Not specified in the provided metadata for M2 or PS4; confirm with your requested configuration.
• Wear resistance vs. toughness: Select the grade that best matches your punching load and alignment sensitivity; higher wear resistance generally comes with trade-offs in toughness depending on final heat treatment.
• Heat treatment state: Not specified in the provided metadata; verify whether the parts are supplied pre-hardened or through a specific quench-and-temper process for your application.

Correct sizing is critical because pilot punches control press alignment by matching the die set’s pilot hole geometry and depth. When selecting a variant, match the shank diameter D and the point length/overall length codes to the corresponding cavity/core pilot requirements.

• Shank diameter D (in): choose within 37 ~ 125 (in the same unit basis as your tooling drawings).
• Length L (coded inch): available ranges include 250 ~ 600, 250 ~ 700, 275 ~ 700, and 300 ~ 700.
• Point length B (coded inch): select from 250 ~ 600, 250 ~ 700, 275 ~ 700, or 300 ~ 700; some configurations list D with 275 ~ 700 and 300 ~ 700.
• P dimension (in): choose within 0.083 ~ 0.999 to match the guided engagement profile.

Tolerance/fit: No tolerance values are provided in the metadata—work to your die set pilot hole tolerances and engagement depth to ensure stable centering and avoid excessive clearance wear.
