Carmex Thread Mills Carbide Mini Type - Metric - M3 x 0.5 - MT7

The Carmex carbide mini thread mill with MT7 shank is a compact, high‑speed threading tool designed for small‑diameter threads such as M3 x 0.5. It’s ideal for precision internal and external threading in tight spaces across a wide range of materials.

• Carbide grade: MT7 sub‑micron substrate with a Titanium Aluminum Nitride multi‑layer coating (ISO K10–K20) for exceptional wear resistance at elevated speeds.
• Coating & coating durability: Triple‑layer TiAlN coating enhances hardness and tool life in tough materials and demanding machining conditions.
• Cutting geometry: Spiral flutes and a short profile deliver rigid cutting action and smooth chip evacuation, especially in deep holes.
• Flute design: 3–5 flutes reduce machining time and improve surface finish on threaded features.
• Coolant through flutes: Through‑flute coolant provides efficient cooling and chip removal in deep‑hole threading applications.
• Versatility: One tool can produce a wide range of thread sizes and pitches and can cut both internal and external threads.
• Materials & hardness: General‑purpose threading suitable for many materials, including hardened alloys up to 45 HRc.
• Application speed: Optimized for medium to high cutting speeds, delivering shorter cycle times and lower cutting forces.

With this mini thread mill, you gain precise, repeatable threads in hard‑to‑access areas, reduced risk of broken taps thanks to its robust, short profile, and the ability to switch between thread sizes without changing tooling. The combination of MT7 rigidity, advanced coating, and through‑coolant capability makes it a reliable choice for micro‑threading in medical devices, electronics housings, and compact mechanical assemblies where small, accurate threads are essential.
