Engineered for speed and precision, Carmex FMT Fast MT solid carbide thread mills are built for high-volume internal threading on CNC machines. This Fast MT model delivers imperial UN threads—UNC, UNF, UNEF, UNS—with a 1/4-28 size and a robust MT8 shank, making it ideal for blind and through-hole applications.
- Threading standard: UN family (UNC, UNF, UNEF, UNS) with a 1/4-28 thread size for broad compatibility across engineered parts.
- Shank type: MT8 Morse-taper shank for secure, rigid mounting in high-speed spindles.
- Material: Solid carbide construction provides hardness and wear resistance for demanding materials.
- Internal coolant bore: Integrated coolant channel delivers coolant directly to the cutting edge, improving cooling and chip evacuation.
- Flute count: High flute count (5–8) delivers faster material removal and smoother milling in threading operations.
- Coating/technology: BLU coating enhances wear resistance and tool life, supporting repeatable thread quality at high speeds.
- Productivity focus: Optimized geometry and flute arrangement reduce cycle times while preserving precision and surface finish.
- Applications: Ideal for internal threading tasks in metal parts, including blind or through-hole operations in a range of alloys.
Carmex FMT Fast MT thread mills are designed to tighten production timelines without sacrificing thread accuracy. The combination of a robust MT8 solid carbide body, multiple cutting edges, and integrated coolant delivery helps you achieve clean, consistent threads on the first pass, reduce tool changes, and extend tool life in high-volume machining environments. With this tool, you can reliably thread mill imperial fasteners in a single operation, unlocking faster setups and improved part quality across aerospace, automotive, and general engineering applications.
