Tapered Tip Ball Lock Pilot Punches (Inch Standard) XNAP Coa

Tapered-tip ball-lock pilot punches are used in injection and stamping-like tooling where the press must repeatedly align die sets before full load. In progressive die assemblies, the ball-lock geometry helps maintain stable positioning, while the tapered tip improves start control for consistent pilot entry.

For connector and bracket housings requiring accurate component location, these inch-standard punches provide reliable guidance to reduce misalignment-induced scrap. The XNAP coating is particularly suited for higher cycle environments because it helps reduce wear at the entry area during frequent press cycles.

They are also a fit for light-duty tooling where designers want predictable pilot performance without the mass of heavy-duty pilot systems. Select the tapered-tip variant when you need smoother engagement into pilot bores and repeatable die positioning in tight tolerance die sets.

• Progressive die sets: stable ball-lock positioning + tapered entry control
• Light-duty precision parts: reliable alignment for connector/bracket features
• Frequent cycles: XNAP coating supports improved wear resistance

This pilot punch is available in M2 or PS4 material options. In general, M2 is an M-series high-speed steel used for parts that require strong wear resistance, while PS4 is selected when a different balance of machinability and service performance is preferred by the die shop.

Typical performance outcomes for these pilot components come from the selected alloy plus its heat treatment state. In many mold and tooling workflows, high-speed steel is used in a quenched and tempered condition to reach stable cutting/wear hardness, supporting good edge retention. For wear-dominant areas like pilot entry, hardness directly affects galling and abrasion resistance, but higher hardness can reduce toughness if not properly tempered.

• M2: emphasizes wear resistance; heat-treated to maintain hardness (HRC not specified in provided data)
• PS4: alternative alloy choice for application-specific toughness/workability balance (HRC not specified in provided data)

Confirm the requested hardness/heat-treatment certificate for your target cycle life since HRC values are not included in the available specifications.

Select the punch size by matching the shank diameter (D) and the overall length/code point length to the mating pilot bore depth in your tool. The provided D (in) range is 0.3750" (37), 0.5000" (50), 0.6250" (62), 0.7500" (75), 0.8750" (87), and 1.0000" (100).

Choose standard point length & L using the coded inch range: 250–600 or 250–700 (as indicated). Depending on the variant you specify, the coded Point Length (B & L) may be 250–600 or 250–700, and the C point length option may extend to 275–700.

• Match D to pilot bore diameter to prevent binding during tapered entry
• Match coded L/point length to bore depth so the ball-lock engages before full stroke
• Use the provided option ranges; tolerances/fit values are not specified in the input data—validate clearances per your die drawing
