Description

The Carmex Thread Mills Carbide – Single Point is a precision internal-thread milling tool designed for professionals who need reliable, small-diameter threads in metal components. Built for CNC and dedicated milling work, it delivers consistent thread forms with a robust MT11 shank and hard-wearing carbide body.

  • Threading capability: Internal threads down to ISO M1 x 0.25 and 0-80 UNF, enabling compact, high-precision assemblies.
  • Profile: Full-profile, single-point trapez (trapezoidal) thread milling for strong, accurate internal threads.
  • Flute configuration: 3–4 flutes for efficient chip evacuation and improved rigidity during cutting.
  • Material and coating: Ultra-fine MT11 carbide with triple blue PVD coating for enhanced wear resistance and longer tool life.
  • Shank: MT11 shank compatible with standard milling setups for easy integration into existing workflows.
  • Depth capability: Thread depths up to 3.5× the thread diameter (dependant on profile) for deeper, more effective internal threading.
  • Sizes: Available in TR16, TR18, and TR20 profiles to fit a range of internal-thread applications.

This tool is ideal for engineers and machinists tackling precision internal threading in hard materials, where clean thread engagement and durable performance matter most. The combination of carbide hardness, PVD coating, and multi-flute geometry helps achieve smooth thread surfaces, tighter tolerances, and longer tool life compared with traditional methods. Use this thread mill for applications such as precision housings, fittings, and components where reliable internal threads are critical, and appreciate the control and consistency it brings to every job.
