The Carmex Thread Mills Carbide Mini Type MT7 is a high-precision threading tool designed for engineers and machinists who need fast, reliable internal and external threads from a compact, single tool. Ideal for deep-hole work and hard materials, it delivers consistent performance at speed.

• Threading capability: Produces a wide range of threads and pitches with one tool, and can create both external and internal threads for versatile applications.
• Size and standards: 5/8 x 18 thread geometry with UNC/UNF/UNEF/UNS compatibility, mounted on an MT7 shank for rigid, accurate machining.
• Material and coating: Sub-Micron MT7 carbide substrate with a Titanium Aluminum Nitride multi-layer coating (ISO K10–K20) for enhanced wear resistance at high speeds.
• Cutting performance: Optimized for medium to high cutting speeds, delivering short machining times and stable results across a range of materials.
• Flute design: Spiral flutes provide smooth cutting action; multi-flute configuration (3–5 flutes) reduces cycle time while maintaining rigidity.
• Coolant and deep-hole capability: Through-flute coolant enhances chip evacuation and cooling in deep-hole applications, improving tool life and surface finish.
• Durability and reliability: Special triple coating and the short, stiff profile minimize cutting forces and extend tool life, reducing the risk of broken taps.
• Material versatility: Capable of machining hardened materials up to 45 HRc, making it suitable for challenging production environments.

This MT7 mini thread mill offers a practical, single-tool solution for a wide range of threading tasks, helping you reduce tool changes, cut precise threads quickly, and maintain consistent quality—even in deep holes or hardened workpieces. Its combination of through-coolant efficiency, spiral flutes, and a robust carbide substrate makes it a reliable choice for high-speed, high-precision threading in professional manufacturing settings.
