Center Dowel Punches for Heavy Load - Metric X Tip

These heavy-load center dowel punches are used during fixture setup and die alignment to create accurate start locations for dowel pin holes. The X-tip variant improves centering performance by guiding the hole formation during assembly, reducing the risk of off-center pilot impressions when parts are repeatedly assembled and disassembled.

• Automotive and industrial connector housings: use in jig setups to locate pin-bearing features on multi-part mold bases and reduce cumulative alignment error across repeated tool change cycles.
• Medical device tooling and small-batch molds: apply as a heavy-duty locating tool to establish consistent dowel hole starts, supporting repeatable cavity-to-core positioning.
• Toolroom die-set alignment: rely on the metric heavy-load body and stable point guidance to maintain repeatability under shop-floor handling.

With metric shank diameters matched to common fixture layouts and an X-tip designed for stable hole guidance, this style is suited for high-frequency locating where centering accuracy directly impacts assembly alignment.

The provided specifications for this series focus on geometry and dimensional ranges; no steel grade, heat treatment state, or hardness (HRC) is explicitly listed in the input data. As a result, material properties such as wear resistance vs. toughness trade-offs, typical nitriding or quench-and-temper conditions, and any specific equivalence (e.g., SKD61 = H13) cannot be stated accurately for this exact configuration.

What can be confirmed from the listing is the functional design: the X-tip geometry and point length/shank diameter combinations are intended to maintain centering stability during heavy-duty locating. For mold builders selecting a steel grade, the usual decision criteria are abrasive wear from repeated contact and impact toughness during punch positioning, but those criteria should be validated against the supplier’s documented material certificate for the specific SKU.

To select the correct center dowel punch, match the shank diameter (D) and point length (L1) to the hole size and the depth of engagement needed for your jig or die-set alignment process.

• D (shank diameter, mm): choose from 10, 13, 16, 20, or 25 based on the guiding bore or locating interface diameter in the fixture.
• L1 (point length, mm): select from 13–19 mm or 19–25 mm depending on how far the punch must penetrate to establish a reliable pilot impression.
• L (overall length, mm): fixed range is 80–130 mm; pick the length that provides safe handling clearance in your setup while still allowing the tip to reach the target surface.

For point and contact stability, review the tip geometry class (H, J, K, L, N, O, R, V, X, Y, Z) and the profile parameters P (1.5–18 mm) and W (1.5–6 mm). Also verify the R value (0.2–5 up to 0.2–12.5 mm depending on configuration) to ensure the contact radius matches your pilot-hole start requirements.
