Metric Heavy Duty Point Larger Than Shank Ball Lock Punches

Where it’s used: In metric injection mold tooling that requires dependable ejection or forming under continuous production loads, such as die blocks and punch sets for blanking and high-cycle forming.

• Automotive and appliance housings: The larger point geometry increases the contact area for stable ball lock engagement, helping maintain ejection consistency when cycle forces fluctuate.
• Precision connectors and terminals: Ball retention stability reduces micro-movement risks during repeated opening/closing, supporting repeatable fit with standard metric tooling systems.
• Medical and industrial device housings: Wear resistance from the XCDP coated heads helps extend punch life in tight maintenance schedules where downtime is costly.

Why this variant fits: The point larger than shank design is intended to support heavy duty ejection performance, while the XCDP coating targets head wear over long production runs.

Material/finish note: The provided data specifies DAYTON XCDP coating for wear resistance but does not list an exact steel grade or explicit heat-treatment state.

Coating impact: XCDP is used to improve surface wear resistance at the punch head/point region where sliding contact and repeated ball engagement produce the highest material removal.

• Wear resistance: Coated heads generally maintain point geometry longer, supporting stable retention and ejection forces across production cycles.
• Toughness trade-off: Harder, wear-focused surfaces can be more sensitive to point edge damage if misaligned; correct fit and alignment are important to preserve toughness at the contact surfaces.

Heat treatment: Since no quench/temper, nitriding, or hardness (HRC) values are included in the input, hardness and specific heat-treatment parameters should be confirmed from the manufacturer’s material datasheet for this series.

Select by shank diameter and geometry: Match the D (Shank dia.) to your metric tooling receiver/block for the ball lock system. Available D values are 13, 16, 20, 25, 32, 40 mm.

• Choose tip shape: Select the appropriate Tip Shape from H, J, K, L, N, O, R, V, X, Y, Z based on required contact profile and ejection behavior.
• Control point length: Keep L1 (Point Length) = 19 to 30 mm within the available tool working envelope to achieve full contact with the part/runner interface.
• Set overall length: Use L (Length) = 80 to 100 mm to align with your cavity/core depth and stripper plate or die block clearance.

Fine engagement check: Verify the series-specific P and W ranges that correspond to your selected D (P: e.g., 13.1–32 / 16.1–38 / 20.1–40 / 25.1–44 / 32.1–50 / 40.1–56 mm, and W: 1.57–34.73 mm) and confirm the required R (0.2–28 mm) for the point contour. Tolerance/fit details are not provided, so confirm fit class with your ball lock housing before installation.
