Ball Lock Pilot Punches Round Tip Heavy Duty Inch XNAP Coati

Ball lock pilot punches are used in injection and stamping toolmaking to create repeatable part positioning during progressive and multi-station operations. This round-tip, heavy-duty variant is especially suited for applications where alignment must remain stable through many press cycles, helping prevent misfeeds, cosmetic variation, and downstream die wear.

• Automotive/industrial connector tooling: Round pilot geometry supports controlled entry into matching ball-lock pockets, maintaining index accuracy under heavy-duty load.
• Medical device component housings and small precision parts: Consistent guidance helps reduce shift between successive molding or forming steps, improving repeatability in thin-wall or tight-tolerance assemblies.
• General progressive die sets and die-sets: The inch configuration aligns with common pilot layout standards, while the XNAP coating is intended to lower friction and wear at the guidance interface.

Material options (M2 or PS4) allow selection based on the expected punch wear rate, making this variant adaptable to higher-cycle production lines.

M2 and PS4 are the available steel options for this ball lock pilot punch line, selected to balance wear resistance and toughness for guidance duties. The XNAP coating works in combination with the steel to help reduce surface friction and improve wear behavior during repeated strokes.

• M2: Typically chosen when higher wear resistance is needed; generally offers a harder wear-oriented performance profile. Trade-off can be reduced toughness compared with more ductile grades, so it should be matched to your load and impact conditions.
• PS4: Often selected for durable performance in tooling environments where stable guidance under cycling is critical; toughness and machinability characteristics can be favored versus higher-hardness tool steels depending on your processing route.

These punches are specified as hardened steel options per the product description. Final hardness is not stated in the provided data, so hardness verification should be confirmed against your supplier’s material certificate for the selected grade and heat-treatment condition.

To select the correct ball lock pilot punch size, match the shank diameter (D) and point length/overall length to the mating ball-lock pocket depth and guide engagement requirement in your die or fixture.

• Shank diameter (D in): choose from the range 37 ~ 125 (inch as provided). Your selected D should be compatible with the drilled/reamed guide and ball-lock receiving components to prevent excessive clearance.
• Point/length options (coded inch): available ranges include 250 ~ 600, 250 ~ 700, 275 ~ 700, and 300 ~ 700 depending on the variant. Use the point length to ensure proper engagement without bottoming.

The P dimension (0.061 ~ 0.999) should be matched to the positional geometry of your alignment system to maintain consistent ball-lock capture. If your design requires tight fit, account for punch-to-pocket clearance and any manufacturing tolerances for both the shank and guidance tip so the punch can enter smoothly while retaining positional accuracy. Length ranges are configurable within the specified codes.
