Key Flat Shank Tapped Punches TiCN Coated

Where it’s used: These keyed flat shank tapped punches are fitted into industrial injection mold tooling stations that perform threaded features via post-mold tapping, insert forming, or screw boss forming in steel and engineering thermoplastics.

Scenario 1 – Automotive connector housings: When molds create features that later require consistent internal thread generation, the keyed shank helps maintain stable alignment under heavy forming load, reducing off-axis tapping and improving repeatability across high-volume cycles.

Scenario 2 – Medical device housings: For tight positional requirements in housing inserts and sealed components, the single-stepped key flat shank provides controlled guidance, helping maintain thread quality while supporting longer run times.

Scenario 3 – Appliance and electronics enclosures: With TiCN (XCN) coating selected, the punch gains wear resistance, which is beneficial for abrasive or high-cycle forming where tool wear can degrade thread accuracy.

• TiCN/XCN coating option is suited for heavy-load forming and extended service intervals
• Keyed flat shank improves guidance to prevent misalignment during tapping operations

Steel options and equivalents (as provided): The punch is available in SKD11 Equivalent (D2) or SKH40 Equivalent (Powdered High-Speed Steel). SKD11/D2 is commonly chosen for balance of wear resistance and toughness, while SKH40 (HSS) is selected where higher hot hardness and cutting performance under load are beneficial.

Surface treatment: Configurations include None or TiCN (XCN) coating. TiCN/XCN improves abrasion resistance at the contact region, helping maintain edge stability during repetitive forming/tapping cycles.

Heat treatment and hardness: The provided dataset lists material grades and coating options, but does not specify exact hardness values (HRC) or the heat-treatment state (e.g., quenched & tempered, nitrided). In selection, treat coating and grade choice as primary performance levers: coated tools typically trade slightly higher brittleness at the surface for reduced wear, while the underlying steel grade governs overall toughness.

• Choose SKD11/D2 for robust wear resistance with good toughness
• Choose SKH40/Powdered HSS for performance where cutting stability under load matters
• Use TiCN/XCN where heavy load and tool-life extension are priorities

1) Start with shank diameter fit: Select the punch D from 6 ~ 25 mm to match the guiding bore/holder and ensure the keyed flat shank geometry seats correctly without excessive clearance.

2) Match tip geometry to thread/form requirement: Choose Tip shape (Round, Rectangle, Oblong, Double Flatted Round, Radius Rectangle) and the tip dimensions P (1.5 ~ 18 mm), W (1.5 ~ 6 mm), and corner radius R (0.15 mm) as required by your tapping/thread-form profile.

3) Verify working length and reach: Confirm L (40 ~ 70 mm) and the full-length alteration options LC (27~79.9, 27~99.9, 32~99.9, 32~99.9, 32~79.9, 32~99.9) that align with your cavity/core thickness and tool stack-up.

4) Consider tolerance/adjustment: Use the provided alteration ranges for PC (0.8 ~ 9 mm) and WC (0.8 ~ 3 mm) to dial in the final effective tip size. If your holder/tap position is tight, prioritize dimensional consistency for stable guidance and reduced misalignment risk.
