Carmex Thread Mills Carbide - Single Point - 55 Degree Partial is a precision threading tool engineered for deep-pocket applications, delivering reliable internal and external threads with tight control and repeatable results.

  • 55° partial-profile threading: specialized geometry optimized for threading deep parts while maintaining accurate thread form.
  • Internal and External threading: versatile capability that covers both male and female thread applications with a single tool.
  • 3-flute design: balanced chip evacuation and rigidity for consistent cuts in challenging depths.
  • Carbide MT11 substrate: ultra-fine sub-micron grade for improved wear resistance and long tool life.
  • Triple blue PVD coating: enhanced wear resistance and reduced friction in demanding materials and coolant conditions.
  • Broad pitch and profile compatibility: supports a wide range of thread pitches and profiles, simplifying part programming.
  • Small-thread capability: capable of producing ISO M1.6 x 0.25 and 0-80 UNF threads for precision small-thread work.
  • Single point, compact form: streamlined geometry ideal for productive, single-step thread milling in confined spaces.

This tool is well-suited for industries that require precise, repeatable threads in hard-to-reach areas—such as mold making, automotive housings, and aerospace components. The combination of 55° partial-profile geometry, multi-flute design, and the advanced MT11 carbide with a durable blue-coated finish helps reduce cycle times, minimize tool wear, and deliver clean thread surfaces with fewer passes. Use it to machine both internal and external threads in deep cavities where traditional tapping or full-profile mills struggle to reach, ensuring fast setup, predictable results, and strong, reliable fasteners in your assemblies.
