The Carmex thread mills Carbide Mini Type MT7 is a compact, high-precision threading tool designed for internal and external UNC/UNF/UNEF/UNS threads in challenging holes, with a 1/2 x 13 size that suits precision fasteners and critical components.

• Thread compatibility: Produces UNC, UNF, UNEF, and UNS threads with a single mini-type carbide mill
• Size & pitch: 1/2" diameter with 13 TPI (1/2 x 13) for versatile threading applications
• Material & grade: Sub-micron MT7 carbide grade for superior rigidity and wear resistance
• Coating: Titanium Aluminium Nitride (TiAlN) multi-layer coating for extended tool life at elevated speeds
• Flute design: Spiral flutes provide smooth cutting action and efficient chip evacuation
• Cutting efficiency: Multi-flute configuration (3–5 flutes) reduces machining time without sacrificing thread accuracy
• Coolant strategy: Coolant-through flutes deliver effective lubrication and debris removal in deep-hole threading
• Depth capability: Short profile and through-flute coolant enable machining in deeper holes with reliable performance
• Material range: General-purpose threading tool suitable for a wide range of materials, including hardened workpieces up to 45 HRC

Designed to maximize productivity, this MT7 mini thread mill enables threading across a broad spectrum of materials at medium to high speeds while maintaining strong cutting forces and precise thread profiles. The ability to generate both internal and external threads with the same tool simplifies setups and reduces tool inventory. Its coating and triple-flute structure deliver longer tool life and faster cycle times, making it a dependable choice for deep-hole threading, complex assemblies, and high-precision fasteners. Whether you’re finishing aerospace components, hydraulic fittings, or automotive fixtures, this carbide mini thread mill offers consistent throughput, reduced risk of broken taps, and reliable performance on hardened surfaces up to 45 HRC.
