Carmex MJ Mini Thread Mills are compact carbide threading tools designed for fast, precise thread milling across a broad material range. Built for internal and external threads in tight or deep-hole applications, these MT7-grade cutters deliver reliable performance with long tool life.

• Carbide grade and coating: MT7 sub-micron carbide with a titanium aluminum nitride (TiAlN) multi-layer coating for exceptional wear resistance and durability.
• Coating technology: Triple-coated construction enhances hardness and heat resistance, boosting tool life in demanding workpieces.
• Cutting speeds: Optimized for medium to high cutting speeds to maximize material removal and reduce cycle times.
• Threading versatility: A single tool can produce a wide range of threads and pitches, suitable for both internal and external threads.
• Deep-hole capability: Coolant through the flutes and the short tool profile enable threading in deep holes with efficient heat management.
• Flute design: Spiral flutes provide smooth cutting action and better chip evacuation for clean, consistent threads.
• Multi-flute efficiency: 3–5 flutes reduce machining time while maintaining thread accuracy and surface finish.
• Material compatibility: Suitable for a broad spectrum of materials, including hardened workpieces up to 45 HRC.

This combination of high-speed capability, deep-hole threading, and versatile thread generation makes the Carmex MJ Mini Thread Mills a dependable choice for precision manufacturing. The ability to machine both internal and external threads with a single tool, along with enhanced life from advanced coatings, helps minimize tool changes, improve consistency, and sustain productivity across diverse projects—from precision fixtures to automotive and hydraulic components.
