Carmex Thread Mills Carbide - Single Point - 55 Degree Partial - x (28-20) - MT11 is a precision threading tool designed to cut both internal and external threads in deep cavities, delivering reliable performance on challenging parts.

• 55° Partial-Profile Geometry: Optimized for deep-part threading with minimized flank interference in tight cavities, delivering clean thread profiles.
• Three Flute Design: Stable cutting action and efficient chip evacuation for long reach operations.
• Carbide Construction: Ultra-fine sub-micron grade carbide for rigidity and precision, backed by a durable tool life.
• MT11 Shank: Versatile mounting compatible with common tool holders for quick setups.
• Triple Blue PVD Coating: A wear- and friction-reducing coating that extends tool life across materials.
• Internal & External Threading: Enables threading on both holes and external fasteners with a single tool.
• Wide Pitch & Profile Support: Handles a broad range of pitches and thread profiles, including the 55° family and standard 0-80 UNF and ISO M1.6 x 0.25 threads.
• Smallest Thread Size: Capable of producing threads as small as ISO M1.6 x 0.25 and 0-80 UNF.

In practice, this tool helps machinists achieve precise, repeatable threads in deep features, reducing the need for multiple passes and post-processing. The 55° partial-profile geometry, combined with the triple blue coating and MT11 shank, supports efficient, consistent results in aerospace components, automotive housings, and precision-machined molds. Use it when you need reliable threading in deep pockets without compromising finish or accuracy.
