Ball Lock Regular Punch Blanks - Light Duty, Inch

These light-duty ball lock punch blanks are used in injection molding and tool-and-die builds where stable punch retention is required during repetitive forming or trimming operations. In progressive and transfer die stations, the ball-lock retention helps maintain consistent punch seating, reducing the risk of tip drift and maintaining repeatable blanking strokes.

• Automotive and appliance connector subcomponents: when forming small sheet or strip features, the controlled point/shank geometry and secure seating improve process stability across high cycle counts.
• Electrical terminal and contact carrier inserts: the option to select M2 (for wear resistance and dimensional stability) supports longer run times where point tips see frequent contact and abrasion.
• General light-duty production fixtures: the inch-coded length ranges (e.g., 200–700, depending on configuration) make it straightforward to match standard die layouts while keeping seating repeatable.

This variant’s ball-lock design and configurable tip shape/length make it especially suited to dies that prioritize consistent engagement and reduced maintenance downtime.

This product is offered in M2, A2, and PS4 steel options, selected to balance wear resistance, toughness, and dimensional stability for punch tooling. M2 is a high-speed steel commonly used for its strong wear resistance; it is typically quenched and tempered to achieve practical hot-hardness and toughness in cutting/forming tools. A2 is an air-hardening tool steel grade, often chosen when a tougher cutting edge and good dimensional stability are required; it is usually oil/air quenched followed by tempering to reach the target hardness. PS4 is provided as an alternative material option for fit and performance needs specified by the supplier’s catalog configuration.

When selecting among grades, note the trade-off: higher wear resistance materials generally require careful heat treatment to avoid brittleness, while tougher grades may show faster wear under abrasive contact. The available material choices are intended to support stable punch seating and reliable blanking in production tooling.

• Typical hardness target: selected by the grade’s heat-treatment route to reach usable punch hardness (HRC), balancing wear vs. toughness.

Selection starts with matching the punch’s shank diameter (D) to the press tool’s guide and retention features. Available D (in) ranges from 25 to 100, so choose the smallest D that fits your station’s allowable clearance while ensuring positive ball-lock engagement.

Next, select the correct tip shape (H, J, K, L, N, O, R, V, X, Y, Z) and configure the working point length and overall length (coded inch). Depending on your build, standard point length & L are offered across 200–500, 200–600, 200–700, and 225–700, with additional coded ranges for B/L (e.g., 225–500, 225–600, 225–700) and C (e.g., 225–600, 225–700), plus a fixed option range of 250–700 for the provided fixed configuration.

• Stroke/engagement matching: use the coded point length (B or C where applicable) to ensure controlled engagement without bottoming in the die opening.
• Fit considerations: keep shank diameter aligned to guide/retainer tolerances so the ball-lock seating remains repeatable across cycles.

Confirm P (0.04–0.75 in) and W (0.04–0.437 in) dimensions as they affect point geometry and engagement depth for your specific station.
