Carmex MT Thread Mills fuse solid carbide durability with a focused threading solution for internal and external NPTF profiles. Designed for machining shops and production environments, these mills deliver reliable, cost-efficient thread creation in a single tool.

  • Threading capability: Internal and external NPTF threading with sizes 1/4-18 and 3/8-18, enabling versatile work on fittings and housings.
  • Flute count: Optimized 3–5 flutes for smooth cutting, stable thread formation, and efficient chip evacuation.
  • Material: Solid carbide construction provides high hardness, wear resistance, and long tool life under demanding threading tasks.
  • Shank: MT7 shank for compatibility with standard milling holders and quick tool changes in busy shops.
  • Tool geometry: Precisely ground edges and flute geometry tailored for clean, accurate thread profiles and consistent results.
  • Operational efficiency: Designed to reduce setup time and tool changes while delivering repeatable threads in production runs.

This single-tool solution excels in environments where precise NPTF threads are essential—such as hydraulic, pneumatic, and fluid-handling components—by delivering dependable performance with a lower total cost of ownership. The MT line focuses on dependable threading performance, helping you achieve tight tolerances and repeatable results across multiple parts without switching tools.
