Carmex Thread Mills Carbide Mini Type - Metric - M2 x 0.4 - MT7

Meet the Carmex Thread Mills Carbide Mini Type, a compact MT7-grade thread mill engineered for high-speed, precision threading in small-diameter metric threads like M2 x 0.4. Designed for engineers and machinists tackling tight spaces, it delivers versatile internal and external threading with exceptional durability.

• Size & pitch: Metric M2 x 0.4 threading with MT7 carbide body for accurate, repeatable threads.
• Material & coating: Sub‑micron MT7 carbide finished with a TiAlN multi‑layer coating (ISO K10–K20) for wear resistance and long life.
• Flute design: Spiral flutes with through‑coolant for smooth cutting action and efficient chip evacuation in deep holes; 3–5 flutes shorten machining time.
• Depth capability: Through‑coolant and short profile enable reliable threading in deep holes with reduced cutting forces.
• Versatility: A single tool capable of producing both external and internal threads across a wide range of pitches.
• Speed & material reach: Optimized for medium to high cutting speeds and capable of machining hardened materials up to 45 HRc.
• Durability: Triple coating and precision grinding extend tool life, supporting high-volume production and repeatable results.

The result is faster cycle times, fewer tool changes, and high‑quality threads in challenging materials and geometries. With its deep‑hole threading capability, coolant through the flutes, and a rigid mini form factor, this Carmex thread mill is well suited for precision fasteners, medical devices, mold components, and aerospace assemblies where small, accurate threads matter.
