Carmex MT7 Solid Carbide Internal Thread Mills are designed for precise UN/UNC/UNF/UNEF/ UNS internal threading in a single, efficient operation. Built for reliability and cost-effectiveness, this tool excels in demanding milling environments where consistent thread quality matters.

• Threading capability: Internal thread milling for UN, UNC, UNF, UNEF, and UNS threads in one operation.
• Flute configuration: 3–5 flutes optimized for stable cutting and efficient chip evacuation.
• Material: Solid carbide construction delivers high rigidity, wear resistance, and long tool life.
• Size and thread pitch: 7/16 x 14 thread with precise geometry for clean, accurate threads.
• Shank: MT7 Morse taper shank for secure mounting in compatible milling centers.
• MT line advantage: Part of Carmex’s MT line, engineered for efficient and affordable threading solutions without sacrificing performance.

By integrating internal thread milling into the machining workflow, this tool helps reduce setup steps and improves thread integrity across materials. The 3–5 flute design enhances cutting stability and chip clearance, supporting consistent thread profiles and better surface finish. The MT7 shank provides robust rigidity, enabling reliable performance at higher speeds while keeping tooling costs predictable.
