Meet the Carmex Carbide Mini Thread Mill—an all-purpose, high-precision tool designed for UN-series threads (UNC, UNF, UNEF, UNS). Built for internal and external threads alike, it delivers reliable performance at medium to high speeds, making it ideal for compact spaces and demanding materials.

• Tool Type: Carbide mini thread mill capable of producing UN threads, including No. 10 x 32, for both internal and external applications
• Material & Coating: MT7 sub-micron carbide with a Titanium Aluminium Nitride multi-layer coating (ISO K10–K20) for enhanced hardness and heat resistance
• Threading Range: Versatile tool that covers a wide range of thread pitches within the UN family, reducing tooling variations
• Cutting Speed & Efficiency: Optimized for medium to high cutting speeds, enabling shorter machining times without sacrificing accuracy
• Flute Design: Spiral flutes provide smooth cutting action; 3–5 flutes shorten cycle times and improve chip evacuation
• Coolant & Depth: Through-flute coolant delivers efficient heat removal and debris clearance in deep-hole threading
• Profile & Rigidity: Short tool profile minimizes cutting forces and deflection, supporting deep-hole threading with stable performance
• Durability & Life: Coating and geometry extend tool life, suitable for machining hardened materials up to 45 HRc

Benefits: This thread mill enables fast, accurate threading without the risk of tap breakage, thanks to its milling approach and robust coating. It handles hard materials with ease, maintains consistent thread pitch and surface finish, and reduces setup time by replacing multiple tools with a single versatile option. The through-coolant design and short profile are particularly advantageous for deep-hole applications, where heat and chip clearance are critical. Whether you’re crafting precision fasteners or integrating threaded features into tight cavities, this Carmex mini thread mill provides dependable performance and long tool life.
