The Carmex Fast MT solid carbide thread mill is engineered for high-speed internal threading, delivering precise 3/8-16 threads with dependable tool life. Designed for professional machinists and production shops, it combines a fast-type geometry with an internal coolant bore to boost throughput on demanding threading tasks.

  • Tool Type: Solid carbide thread mill with Fast MT geometry optimized for high-speed threading
  • Flute Count: Large flute count (5–8) to reduce machining times and improve thread quality
  • Internal Coolant Bore: Directs coolant to the cutting edges for improved cooling, chip evacuation, and longer tool life
  • Size and Thread Forms: 3/8-16 thread size compatible with UNC, UNF, UNEF, and UNS internal thread forms
  • Shank Interface: MT8 Morse taper shank for secure, rigid toolholding on standard milling machines
  • Material: Solid carbide for exceptional wear resistance and durable performance in tough materials
  • Applications: Ideal for precise internal thread milling in holes and pockets across a range of metals

With its combination of a high-flute, fast-type geometry and an efficient internal coolant bore, this thread mill accelerates production while preserving thread accuracy and clean finishes. The carbide construction delivers reliable wear resistance for repeated threading cycles, supporting longer tool life and consistent results. The MT8 interface ensures stable, robust performance in demanding setups, making it a solid choice for shops aiming to improve throughput on 3/8-16 internal threads.
