Description
The Carmex External Thread Mill is a precision solid carbide tool designed for UNJ-thread milling on CNC mills. It delivers exceptional surface finishes and efficient cutting for a wide range of metalworking applications.
- External thread milling: Engineered to produce UNJ family threads (UNJC, UNJF, UNJEF, UNJS) with accurate profiles and consistent results.
- Solid carbide construction: Delivers rigidity, wear resistance, and long tool life in demanding machining environments.
- Size and shank: 8 mm cutting diameter, 28 mm flute length, MT7 shank for compatibility with high‑speed spindles.
- Spiral flute geometry: Spiral flutes contribute to a superior surface finish on the threaded part.
- Multi-flute design: Three to five flutes balance cutting speed and finish, reducing overall machining time.
- Application versatility: Suitable for a wide range of metal components requiring precise UNJ external threads in industrial settings.
The combination of spiral flutes and a multi‑flute arrangement enables efficient threading operations while delivering a smooth, high‑quality thread profile. This makes the tool a reliable choice for shops pursuing precise UNJ threading with consistent results on standard CNC equipment.
