The Carmex Thread Mills Carbide Mini Type is a compact metric thread mill designed to deliver precise M4 x 0.7 threads with MT7 tooling. Built for machinists who need versatile, high-speed threading across a range of materials, including hardened steels, with the durability of carbide and advanced coatings.

• MT7 carbide grade: Sub-Micron precision carbide designed for tight tolerances and long tool life.
• TiAlN multi-layer coating: Titanium Aluminium Nitride coating (ISO K10–K20) delivers heat resistance and wear protection across hard materials.
• Metric thread form: M4 x 0.7 mini-type thread mill capable of producing multiple pitches with a single tool.
• External and internal threads: One tool that can mill both external and internal threads, reducing setup changes.
• Through-flute coolant: Coolant through the flutes enhances chip evacuation and cooling in deep-hole applications.
• Spiral flute design: Spiral flutes provide smooth cutting action and efficient debris removal for cleaner threads.
• High-speed performance: Optimized for medium to high cutting speeds with shorter machining times and lower cutting forces.
• Material capability: Suitable for a wide range of materials, including hardened workpieces up to 45 HRc.
• Reliability in deep holes: Short profile minimizes cutting forces and reduces the risk of tap breakage in deep-hole threading.

This thread mill is engineered to streamline production by delivering consistent thread quality, reducing tool changes, and enabling deep-hole threading with through-coolant efficiency. Ideal for precision components, hydraulic fittings, and high-accuracy assemblies where both speed and accuracy matter.
