Carmex Thread Mills Carbide - Single Point is a high-precision full-profile tool designed to create internal threads in metal parts. Built for shops and manufacturers that require reliable small-to-medium thread sizes, it delivers consistent, clean threads in ISO metric and imperial standards.

• Tool type: Full-profile carbide thread mill for internal threading
• Thread compatibility: Supports ISO M1 x 0.25 and 0-80 UNC/UNF/UNEF/UNS internal threads
• Size and drive: No. 4 x 40 with MT11 drive
• Flutes: 3–4 flutes for stable cutting and efficient chip evacuation
• Coating: Triple blue PVD coating for wear resistance and reduced friction
• Material: Carbide for rigidity and heat resistance in demanding materials
• Depth capability: Thread depth up to 3.5× thread diameter (dependent on profile)
• Grade: MT11 ultra-fine sub-micron grade for precise finishing

This internal-thread milling solution enables precise threading in a single operation, enhancing concentricity and finish quality. The carbide construction provides stiffness for steady milling, while the MT11 ultra-fine grade and PVD coating extend tool life and maintain tight tolerances in challenging metals. The tool’s depth capability supports deeper holes without needing multiple tools, and the 3–4 flute design improves chip evacuation and reduces cutting chatter, delivering reliable results for housings, adapters, and other threaded components that must meet strict dimensional standards.
