Description

Carmex Thread Mills Carbide - Single Point - Metric - M1.4 x 0.3 - MT11 is a precision internal-thread milling tool designed for miniature components and tight cavities. Built for machinists who demand clean, accurate threads in hard materials, it combines exceptional edge integrity with durable coatings to extend tool life.

  • Size and thread capability: Metric M1.4 x 0.3 single-point thread mill; supports ISO M1 x 0.25 and 0-80 UNF threading.
  • Shank: MT11 to fit standard tool holders with secure, stable cutting performance.
  • Material and construction: Solid carbide with a full-profile geometry for precise thread formation.
  • Flute count: 3–4 flutes for efficient chip evacuation and improved surface finish on small-diameter threads.
  • Coating and grade: Triple blue PVD coating combined with MT11 Ultra-fine sub-micron grade for reduced wear and extended life.
  • Depth capability: Thread depth up to 3.5× the thread diameter, depending on profile, enabling deeper internal threads in a single setup.
  • Profile: Full-profile design ensures accurate thread form and strong engagement with workpieces.

This carbide thread mill delivers dependable, repeatable internal threads in cramped spaces—ideal for miniature fasteners, compact housings, precision instruments, and electronics enclosures. The combination of a robust MT11 shank, multi-flute geometry, and advanced coating provides reliable performance, even in demanding materials, while supporting both metric and imperial small-thread standards. Use cases include precise internal threading in tight pockets, quick-depth threading where space is limited, and workflows that benefit from fewer passes and consistent thread quality.
