Carmex Thread Mills Carbide - Single Point - UN (UNC UNF UNEF UNS) - No. 2, No. 3 x 56 - MT11

Carmex Thread Mills Carbide — Single Point are precision internal-thread milling tools built for small, accurate threads in tight cavities. Designed for engineers and machinists using CNC machines, these full-profile mills cut UNC/UNF/UNEFS/UNS and metric ISO threads with exceptional control.

• Threading range: Internal thread milling for ISO metric M sizes (e.g., M1 x 0.25) and UNC/UNF/UNEFS/UNS threads up to 0-80 UNF, enabling a broad set of common thread standards with one tool family.
• No. 2 & No. 3 x 56: Available in No. 2 and No. 3 sizes with a 56 mm length, offering compact yet capable reach for confined holes and blind depths.
• Flute design: 3–4 flutes tuned for efficient chip evacuation and stable cutting in a variety of metals, from alloys to hardened materials.
• Shank interface: MT11 Ultra-fine sub-micron carbide with a rigid MT11 shank interface for precise alignment and reduced runout in demanding setups.
• Coating and grade: Ultra-fine sub-micron carbide grade with triple blue PVD coating for wear resistance and extended tool life in abrasive environments.
• Depth capability: Thread depth capability up to 3.5 times the thread diameter, depending on profile, enabling deeper threaded features without multiple tools.
• Full-profile thread mills: Specifically engineered to create clean internal threads in a single operation, minimizing recuts and improving dimensional accuracy.

These features translate to practical advantages: tight, reproducible thread profiles in small-diameter holes, longer tool life from a hard-wearing coating, and reliable performance across a range of materials. The combination of MT11 shank compatibility, multi-flute geometry, and wide threading range makes these Carmex thread mills a robust choice for precision assemblies, aerospace housings, medical devices, and automotive components where clean internal threads matter.
