The Carmex Carbide Mini Thread Mill MT7 is a compact, high-performance threading tool designed for metric threads (M10, M14, M16 x 1.5). It delivers reliable internal and external threading with fast cycle times and long tool life, making it ideal for professional machining environments.

• Tool material: MT7 sub-micron carbide with a Titanium Aluminium Nitride multi-layer coating (ISO K10–K20) for enhanced wear resistance and heat management.
• Threading capability: Produces both internal and external metric threads across a range of pitches with a single tool, reducing tool changes.
• Thread sizes: Optimized for metric threads M10, M14, and M16 with 1.5 mm pitch.
• Flute design: Spiral flutes provide smooth cutting action and efficient chip evacuation; 3–5 flute configuration enables calmer cutting and shorter cycle times.
• Coolant through flutes: Through-the-flute coolant delivers effective cooling and chip removal, especially advantageous for deep-hole threading.
• Cutting performance: Designed for medium to high cutting speeds with a short profile that reduces cutting forces and accelerates machining time.
• Material reach: Capable of machining hardened materials up to 45 HRc, expanding its use to tougher components without compromising performance.
• Coating durability: Specialized triple coating enhances tool life, supporting long production runs and consistent results.
• Versatility: A single tool enables a wide range of threads and pitches, making it a flexible option for mixed-threading tasks and complex geometries.

This MT7 mini thread mill is built to streamline production: you can tackle both internal and external threads with one tool, optimize cycle times with its multi-flute design, and maintain accuracy when threading into deep holes thanks to coolant-through capability. The combination of a sub-micron carbide core and a robust TiAlN multi-layer, triple-coated finish translates to extended tool life and steadier performance across materials, including hardened steels. Whether you’re outfitting a small shop or a precision-focused production line, this thread mill helps you achieve clean, dependable threads with fewer tool changes and downtime.
