Ball Lock Pilot Punches Round Tip Light Duty Inch XCN Coatin

Ball-lock pilot punches with a round tip are used to establish repeatable center locating in injection mold tooling, progressive dies, and secondary fixture stations where part positioning must remain stable during cycle time.

Common scenarios include:

• Automotive or industrial connector housings: round-tip pilots guide the component during molding or insert placement, helping maintain consistent cavity alignment in light-duty production setups.
• Appliance and housings dies: used as locating pilots in die maintenance or tool build-outs to keep punches and forming features centered as tooling is cycled.
• General die and fixture locating: the ball-lock style supports controlled engagement, while the round tip supports smooth entry for improved positioning repeatability.

The availability of inch-series light-duty options with an XCN coating makes this variant particularly suited for reducing friction and supporting steadier wear under lighter service conditions.

This series is offered in M2 and PS4 materials. When selecting for punch applications, M2 is typically chosen for its high hardness capability and strong wear resistance, while PS4 is selected when a different balance of toughness and machinability is preferred for light-duty pilot use.

• M2 (AISI M2 equivalent, commonly used as a high-speed steel base): best suited where wear resistance is critical; hardness is typically targeted in the hardened range (commonly up to the mid- to high-HRC values) after standard hardening and tempering.
• PS4: used as an alternative steel option; the final hardness and wear performance will depend on the supplied heat treatment state for your tooling workflow.

Regardless of grade, proper quench & temper (for hardened tool steel options) is essential to achieve the trade-off between wear resistance and toughness needed to prevent chipping at the pilot tip during repeated engagement.

To select the correct ball-lock pilot punch, match the shank diameter D and the point/length options to your core/cavity locating requirements and clearance for the mating wear surface.

• Shank diameter D (in): choose from 25 ~ 100.
• Point length & L (coded inch): available in multiple ranges, including 200 ~ 500, 200 ~ 600, 200 ~ 700, and 225 ~ 700 depending on the specific configuration.
• B/C point length variants (coded inch): options include 225 ~ 500, 225 ~ 600, 225 ~ 700, and configurations such as 250 ~ 700 where point length is fixed.
• P dimension (in): select within 0.05 ~ 0.749 to fit the required engagement depth.

Confirm fit by checking the mating hole tolerance and ball-lock engagement clearance; pilots should allow controlled insertion without binding, while still ensuring positional repeatability over many cycles. Fixed vs. variable length ranges depend on whether your selected configuration uses the 250 ~ 700 fixed point-length specification or one of the variable ranges.
