Introducing the Carmex FMT/Fast MT solid carbide thread mill—a high-performance tool designed for rapid, precise threading in metalworking environments. Built for machinists and production floors that demand speed without compromising thread quality, it delivers reliable UNC, UNF, UNEF, and UNS threading in a 5/16-24 size with an MT8 shank.

  • Material: Solid carbide construction for exceptional rigidity and wear resistance across demanding threading tasks.
  • Flute Count: 5–8 flutes to increase material removal rates and shorten cycle times.
  • Internal Coolant Bore: Directs coolant to the cutting edges and aids chip evacuation for better heat management.
  • Shank: MT8 shank design for broad machine compatibility and secure tool retention.
  • Thread Compatibility: Optimized for UNC, UNF, UNEF, and UNS threads; sized at 5/16" diameter with 24 threads per inch (5/16 x 24).
  • Fast Type Geometry: Geometry tuned for high-speed threading that maintains accuracy and finish.

Designed for high-production threading, this tool reduces cycle times, maintains clean, accurate threads, and offers dependable performance under coolant-assisted cutting. The combination of a dense flute arrangement and internal cooling makes it well-suited for demanding applications where fast, repeatable threaded features are essential—whether manufacturing fasteners, fittings, or precision components on steel, aluminum, or other common metals. The MT8 shank and universal thread compatibility simplify tooling setups, helping shops improve uptime and consistency across threaded workpieces.
