Carmex Mini Type solid carbide thread mill is engineered for precise internal threading in hardened materials, making it ideal for shops tackling tough steels and precision components. Designed to deliver reliable cuts and a superior surface finish, it’s built for performance in demanding environments.

  • Tool Type: Mini internal thread mill designed for UN thread standards (UNC, UNF, UNEF, UNS) to create accurate threads in a single setup.
  • Diameter and Pitch: 7/16" diameter with 14 threads-per-inch (7/16 x 14), a common imperial thread size for many applications.
  • Shank: MT9 Morse taper shank for secure mounting on a wide range of milling machines.
  • Material: Solid carbide for exceptional wear resistance and sustained performance when cutting hardened workpieces.
  • Material Capability: Specifically designed for materials up to 62 HRC, enabling threading in tough steels and alloys.
  • Finish Quality: Optimized flute geometry and cutting edges to produce clean thread profiles and an excellent surface finish.
  • Applications: Ideal for internal threading in molds, dies, automotive components, aerospace hardware, and other precision parts where hard materials are standard.

Using Carmex Mini Type thread mills helps you avoid tapping limitations on hardened materials, delivering consistent thread accuracy, reduced tool wear, and a reliable finish across production runs. The compact form fits into tight cavities and short pockets, while the robust MT9 shank ensures rigid, vibration-free cutting for repeatable results. This tool is a practical choice for high-precision manufacturing environments that demand quality threads without compromising productivity.
