Carmex Thread Mills Carbide Mini Type - UN (UNC UNF UNEF UNS) - No. 1 x 72 - MT7 is a compact carbide thread milling tool designed for high‑speed, precise threading of UNC/UNF/UNEF/UNS threads. It’s built for versatility, efficiency, and long tool life in both internal and external threading tasks.

• Thread compatibility: Handles UNC, UNF, UNEF and UNS threads with a No. 1 x 72 size for versatile threading in a single tool.
• Material & coating: MT7 sub‑micron carbide with a TiAlN multi‑layer coating for extended life and improved wear resistance (ISO K10–K20).
• Cutting performance: Optimized for medium to high cutting speeds; short profile reduces cutting forces and deflection in challenging contours.
• Flute design: Spiral flutes with coolant‑through channels for efficient cooling and chip evacuation in deep holes; 3–5 flute geometry enhances rigidity and stability.
• Versatility: Enables threading a wide range of materials, including hardened workpieces up to 45 HRC, with a single tool capable of producing both internal and external threads.
• Durability: Triple coating extends tool life and reduces wear, helping prevent common issues like tap breakage in demanding operations.

This thread milling solution delivers smooth, accurate threads at higher speeds, reducing cycle times without sacrificing precision. The through‑flute coolant and short profile improve hole quality and cutting stability in deep‑hole applications, while the MT7 carbide substrate and advanced coating offer dependable performance across a broad material range. Ideal for shops that require a single, reliable tool to handle multiple thread pitches and both internal and external threads.
