The Carmex Thread Mills Carbide Mini Type MT7 is a compact, high‑performance threading tool designed for internal and external threads in UNC, UNF, UNEF, and UNS standards. Built for medium to high-speed machining, it delivers versatile threading in a single, durable tool.

• Size: No. 2 x 80 (diameter x length)
• Material & coating: Carbide MT7 substrate with a sub‑micron grade and a TiAlN multi‑layer coating (ISO K10–K20)
• Coating durability: Special triple coating for extended tool life and wear resistance
• Cutting speeds: Optimized for medium to high cutting speeds and high‑speed machining
• Threading capability: Produces both internal and external threads across UNC, UNF, UNEF, and UNS forms with a single tool
• Coolant through flutes: Through‑coolant design provides effective cooling and chip evacuation, especially in deep holes
• Flute design: Spiral flutes for a smooth cutting action and reduced vibration; 3–5 flutes for efficient, rapid material removal
• Depth performance: Enables machining in deep holes with stable threading andthrough‑the‑hole coolant
• Machinability for hard materials: Capable of threading hardened materials up to 45 HRC
• Profile advantage: Short profile delivers lower cutting forces and helps prevent tool chatter and breakage

This MT7 carbide mini thread mill combines versatility and reliability: a single tool that can handle a wide range of thread sizes and pitches, suitable for both small‑diameter through holes and challenging deep‑hole applications. The combination of a high‑quality coating, optimized flute geometry, and through‑coolant support translates into accurate threads, longer tool life, and shorter cycle times—ideal for precision machining environments that demand consistent results and minimal downtime.
