Carmex Thread Mills Carbide Mini Type MT7 is a precision metric thread milling tool designed for high-speed, accurate threading on small diameters (M3 x 0.5) with a Morse MT7 shank. Built for performance in a range of materials, it’s ideal for shops needing reliable small-thread production with quick cycle times.

• Thread size: Metric M3 x 0.5 threading capability with MT7 shank for compatibility with common milling setups.
• Material and coating: Sub-micron carbide grade MT7 with a TiAlN multi-layer coating (ISO K10–K20) for extended life at speed.
• Flute configuration: Spiral flutes (3–5 flutes) for smooth cutting action and efficient chip evacuation.
• Through-coolant: Through-flute coolant enhances heat management and depth of hole threading results.
• Cutting speed and efficiency: Designed for medium to high cutting speeds to reduce cycle times without sacrificing accuracy.
• Profile and rigidity: Short tool profile reduces cutting forces, helping prevent tool chatter and broken taps.
• Versatility: Capable of producing both internal and external threads across a wide range of pitches with a single tool.
• Depth capability: Optimized for deep-hole threading, enabling longer reach in challenging workpieces.
• Material tolerance: Suitable for threading hardened materials up to 45 HRc, expanding the range of applications without changing tools.

This miniature carbide thread mill delivers precise, repeatable results for small-diameter threads, making it a reliable choice for precision components, tight-tolerance assemblies, and high-throughput workshops. The combination of through-coolant, multi-flute design, and a tough MT7 shank translates into longer tool life, cleaner threads, and fewer interruptions on production runs.
