Inch Standard Ball Lock Pilot Punches Tapered Tip CRN Coatin

Inch-format pilot guidance components like these are used in die and press tooling where stable alignment is needed during repeated operation. The tapered nose supports smooth initial engagement, helping reduce scuffing and misalignment when the punch enters the guided station.

• Die set guiding and locating: Use in ball-lock guiding arrangements to improve pilot positioning accuracy and stabilize part-to-die orientation through cyclic press loads.
• Light-duty forming and stamping dies: The ball-lock pilot design helps maintain consistent engagement, while the CRN-coated surface improves resistance to intermittent wear from repeated contact.
• Inch tooling standardization: The specified inch shank diameters (0.3750" to 1.0000") and inch point lengths support compatibility with common U.S. die/punch build practices.

These features make the tapered tip and CRN coating well suited when engineers need predictable alignment with manageable wear in lighter duty applications.

This variant is offered with M2 or PS4 material options, selected to balance wear resistance and toughness for pilot and guidance duties. M2 (tool steel in the HSS family) is commonly used where edge integrity and wear resistance matter; it is typically supplied in a quenched & tempered condition and then finished to the required geometry for consistent guidance.

• Wear performance: The CRN coating increases surface hardness and helps resist cyclic surface abrasion.
• Toughness trade-off: Harder, more abrasion-resistant conditions can reduce impact tolerance; for lighter-duty guidance, the coating helps maintain surface life without relying solely on bulk hardness.
• Material comparison: If you need enhanced wear under repetitive guidance contact, M2 is typically favored; PS4 provides an alternate steel choice within the same die component role, depending on your internal spec and processing targets.

Hardness values (HRC) are not provided in the supplied data, so final hardness should be verified against the manufacturer’s material cert for your selected option.

To select the correct dimensions, match the pilot punch shank diameter (D) and the point length (L) to the guiding and locating requirements of your die set. Available shank diameters are 0.3750" (37), 0.5000" (50), 0.6250" (62), 0.7500" (75), 0.8750" (87), and 1.0000" (100).

• Length selection: Standard point length & L are coded as 250–600 or 250–700 depending on the configuration. For the fixed-point option, the range is 275–700.
• Point-length variation: B (point length) & L are available in 250–600 or 250–700; another configuration adds 275–700 as an additional range.
• Tolerance/fit: Ensure the selected D and point length correspond to your mating ball-lock guide and counterbore depths so the tapered tip achieves full engagement without bottoming.
• Configurable vs fixed: D and L ranges are variable, while one option explicitly specifies a fixed D point length range of 275–700.

Finally, confirm the P dimension (0.083–0.749 in) aligns with your design’s spacing and engagement geometry.
