Carmex Thread Mills Carbide — a precision single-point, 55° partial-thread mill designed for deep threading in hard-to-reach locations. Built for machinists who demand reliable internal and external threads with consistent, high-quality finishes.
- 55° partial-profile design: optimized for deep parts and long bores, delivering accurate thread geometries where space is limited.
- Three-flute geometry: stable cutting action and efficient chip evacuation for clean, precise threads in challenging materials.
- Carbide MT11 ultra-fine sub-micron grade: exceptional hardness and wear resistance for extended tool life and repeatable performance.
- Triple blue PVD coating: reduced friction and enhanced wear protection to sustain accuracy over many cycles.
- Internal and external threading capability: versatile tool suitable for a wide range of thread milling tasks in one setup.
- Broad pitch compatibility: supports threads from ISO M1.6 x 0.25 up to 0-80 UNF, enabling use across numerous standards and applications.
- Single-point, high-precision threading: designed for consistent thread form and tight tolerances in deep features.
This thread mill helps you achieve reliable, repeatable threads in deep pockets and long holes without compromising surface finish. The combination of MT11 shank compatibility, 3-flute stability, and advanced coating means fewer tool changes, lower cycle times, and longer tool life. Ideal for precision machining across industries such as automotive, aerospace, moldmaking, and general engineering where deep-thread accuracy matters.
