Carmex Thread Mills Carbide Mini Type - Metric - M2.2 x 0.45 - MT7

The Carmex Carbide Mini-Type Thread Mill is a precision metric threading cutter designed for M2.2 x 0.45 threads with an MT7 shank. Built for reliable internal and external threading at high speeds, it’s ideal for machinists who need accurate results on small, hard-to-machine features.

• Threading capability: Produces both internal and external threads with a single tool across a wide range of pitches.
• Shank/interface: MT7 tool interface for secure, vibration-free mounting in standard milling machines.
• Coating and carbide grade: Sub-micron MT7 carbide with a TiAlN multi-layer coating (ISO K10–K20) for enhanced heat and wear resistance.
• Flute geometry: Spiral flutes provide smooth cutting action; 3–5 flutes reduce machining time and improve chip evacuation.
• Coolant through the flutes: Through-flute coolant design supports deep-hole threading with efficient cooling and debris removal.
• Cutting speed and efficiency: Optimized for medium to high cutting speeds with lower cutting forces thanks to the short profile, enabling quicker cycles.
• Material versatility: Capable of machining hardened materials up to 45 HRC, extending its usable range across tough workpieces.
• Deep-hole capability: Short profile and through-coolant enable reliable threading in deep holes without sacrificing precision.

Benefits: This single, well-rounded tool streamlines production by covering a broad spectrum of metric threads, dramatically reducing tool changes and setup time. The through-coolant design and three-to-five-flute geometry promote consistent thread quality in deep holes, while the triple coating extends tool life under demanding speeds and hard materials. For small, precise threaded features in medical, automotive, aerospace, or general precision manufacturing, you get reliable performance, tighter tolerances, and longer intervals between tool retentions.
