Carmex Thread Mills in solid carbide Fast Type are designed for machinists who demand precise, durable threaded holes in the toughest materials. Built to handle hard alloys and superalloys, these cutters deliver clean UN thread forms with reliable stability.

• Thread forms: Supports UN family threads (UNC, UNF, UNEF, UNS) for versatile, plug-and-thread applications.
• Size and shank: No. 6 x 32 thread size with MT3 ultra-fine shank for strong, rigid seating in the spindle.
• Material and coating: Solid carbide with a multi‑layer PVD coating for superior heat resistance and wear protection.
• Flute design: FSH family features a high flute count (up to 7 flutes on some models) to improve chip evacuation and cutting stability.
• Hard-material performance: Engineered for hard workpieces up to 65 HRC and capable of machining demanding superalloys.
• Cutting type: Fast Type geometry optimized for efficient material removal while preserving thread accuracy and surface finish.

This tool excels in producing repeatable, high‑quality threads in hardened steels, nickel-based alloys, and other challenging materials. The combination of an ultra‑fine MT3 shank, multi‑layer PVD coating, and up-to‑7‑flute geometry translates to longer tool life, reduced deflection, and consistent thread profiles across production runs. Ideal for precision components in aerospace, automotive, and high‑performance engineering, it helps you achieve reliable threading with minimal downtime and tight tolerances.
