XNAP Coated Point Larger than Shank Ejector Ball Lock Punches - Light Duty

This light-duty ball-lock punchpoint variant is used in injection and die tooling where retention consistency and ejection smoothness are critical. The larger point than the shank helps maintain stable positioning during repeated punching cycles, which is especially helpful in compact press configurations and smaller tooling cavities.

• Automotive interior/trim brackets: supports reliable press-fit retention in thin-to-medium gauge forms where misalignment can accelerate wear at the punch point.
• Appliance housings and small structural stampings: the increased point geometry improves functional stability as parts cycle through progressive or turret stations.
• General light-duty forming and punching fixtures: the XNAP coating is selected to promote smoother ejection and reduce surface wear under intermittent high-contact loads.

Select this configuration when you need predictable ball-lock seating combined with reduced friction at the point, while staying within light-duty tooling requirements.

The provided metadata specifies XNAP coating for light-duty performance; however, no base steel grade or heat-treatment data is included. For accurate hardness, wear-resistance expectations, and compatibility with your press load profile, request the underlying steel and coating thickness from the supplier documentation tied to the specific series code.

• XNAP coating: used to improve sliding behavior and reduce point wear, supporting smoother ejection over repeated cycles.
• Hardness and toughness trade-offs: without the steel grade and heat-treatment state, hardness (HRC) and toughness cannot be verified from the input data; these parameters should be confirmed for your die material and press tonnage.
• Material comparison: if alternative steels or coating systems are offered for other duty ratings, higher-hardness options typically raise wear resistance but can reduce toughness if not tempered appropriately.

Use the tip-shape options (H/J/K/L/N/O/R/V/X/Y/Z) to tune contact geometry, while validating the steel/coating specification for your target life and load conditions.

Correct selection is driven by matching the shank diameter (D), overall length (L coded inch), and the functional point dimensions (P, W, R) to the corresponding ball-lock punch pocket and clearance conditions in your mold or die set.

• Shank diameter D (in): choose from 0.3750, 0.5000, 0.6250, 0.7500, 0.8750, or 1.0000 depending on the ball-lock retention seat.
• Length L: select from the fixed coded inch range 250 ～ 450 to achieve the required protrusion and safe engagement under your tooling stack-up.
• Point geometry: match P within the available bands (0.376～0.875, 0.501～1.25, 0.626～1.5, 0.751～1.5, 0.876～1.75, 1.001～1.75 in), and pair with the available W (0.062～0.867 in) and R (0.007～0.4375 / 0.007～0.625 / 0.007～0.75 / 0.007～0.875 in) to control tip radius and clearance contact.

Because tolerances are not provided in the input data, verify the manufacturer’s fit tolerances for your punch pocket and retention mechanism before finalizing the cavity/core dimensions. Tip shape selection (H, J, K, L, N, O, R, V, X, Y, Z) should be aligned with your die cutting geometry.
