Ball Lock Pilot Punches - Round Tip, Light Duty, Inch, XNAD

These ball lock pilot punches are used in injection and press tooling where repeatable part registration is critical, such as automotive connector housing and terminal alignment molds. The round tip supports consistent pilot entry into the corresponding ball-lock bushing features, helping maintain location through multiple press cycles.

In appliance and consumer product housings, the light-duty inch format and controlled point length codes help designers tune engagement depth for stability during blanking, piercing, and knock-out related operations.

For general die sets that prioritize dimensional accuracy over extreme sliding wear, the XNAD coating is suited to reduce surface-related wear and improve tooling performance where normal production loads are expected.

• Round tip geometry for repeatable alignment and stable pilot positioning
• XNAD coating to manage wear in production use
• Light-duty inch variants for controlled point length matching to cavity/core requirements

Ball lock pilot punches in this series are offered with M2 or PS4 as the punch material option. M2 is a high-speed steel selection commonly chosen for balanced wear resistance and toughness in cutting and punching environments; performance is typically optimized via standard tool-steel heat treatment cycles (quench and temper to achieve the required service hardness).

PS4 is provided as an alternative material choice for tooling applications where designers want a different balance of surface durability and toughness based on the supplier’s intended heat-treatment and use case.

• M2: high wear resistance with robust toughness through heat treatment (quenched & tempered)
• PS4: alternative steel grade option for designers to match expected load and wear conditions
• Trade-off: higher hardness generally improves wear resistance, while toughness must be maintained to resist chipping under alignment loads

For exact HRC targets and the specific heat-treatment state for each material option, confirm the final material/heat lot documentation against your procurement specification.

Select the pilot punch based on the mating ball-lock system and the required engagement length. Use the shank diameter D range from 25 ~ 100 (in) to match the bushing/ball-lock pocket diameter in your die set.

Then choose the coded point length option according to the required penetration depth. The series provides point length code ranges including 200 ～ 500, 200 ～ 600, 200 ～ 700, and 225 ～ 700, with additional combinations for B and L such as 225 ～ 500, 225 ～ 600, and 225 ～ 700. A fixed configuration is also available for 250 ～ 700 point length (B & L).

• Match D to the ball-lock housing diameter for correct fit and guidance
• Select the point length code (200–700 family) to control engagement depth and alignment stability
• Use P = 0.05 ~ 0.749 to ensure the required functional clearance/profile at the locating interface

When fitting into a die set, maintain proper clearance for press cycling; use the supplier’s tolerance/fit tables for the final ball-lock system to avoid binding or excessive play.
