Product Guide
Application Scenarios+
These tapered-tip, light-duty ball lock pilot punches are used to establish repeatable die-to-die alignment in injection and press tooling where start-up force must be minimized. The tapered nose guides the punch into the mating ball-lock bushing during each cycle, helping reduce misalignment at high cadence.
Automotive and appliance progressive dies: Suitable for progressive/transfer stations that require stable locating under short travel and frequent indexing. The light-duty geometry supports consistent part localization without overloading the pilot system.
Small precision components: When aligning thin housings, brackets, or connector subcomponents, the inch locating body sizes (D = 0.3750" to 1.0000") allow designers to match common pilot station layouts while preserving repeatability.
- Tapered tip geometry supports guided entry and stable alignment
- Ball-lock style location improves repeatable setup in pilot stations
- Inch series dimensions fit standard pilot die designs
Material & Process Details+
Available materials for this punch are M2 and PS4, both intended for hardened tooling service and improved wear resistance in locating features. M2 is typically selected for its balanced wear resistance and toughness, while PS4 is commonly used when designers prioritize stable wear behavior under light-duty cycle demands.
Heat treatment state: The product description indicates a hardened wear-resistant construction. This generally corresponds to a quenched and tempered condition for high-speed steel (M2) or an equivalent hardened state for PS4, producing higher surface hardness for the taper and seating areas.
- Hardened wear resistance supports consistent ball-lock engagement
- Wear vs. toughness trade-off: higher hardness improves scuff resistance but can reduce impact toughness if misused
- Material selection affects long-term locating stability in repeated alignment cycles
Sizing & Selection Guide+
Select the shank diameter D to match the pilot station tooling and mating bushing/guide size. Available inch shank diameters are 0.3750" (37), 0.5000" (50), 0.6250" (62), 0.7500" (75), 0.8750" (87), and 1.0000" (100). Use the specified point length range to ensure full seating of the taper and correct ball-lock engagement depth.
For standard point length & L, ranges are coded 250 ~ 600 or 250 ~ 700 depending on configuration. B point length has the same coded ranges (250 ~ 600 or 250 ~ 700), while C offers 250 ~ 600 and 275 ~ 700 options. A fixed configuration is noted as 275 ~ 700 for [D] point length & L.
- Match D to cavity/core pilot hole and bushing bore layout
- Verify point length range to prevent under-engagement or bottoming
- P = 0.083 ~ 0.749 must correspond to the required taper/clearance geometry in your design
