Carmex MT3 Thread Mills are precision solid carbide tools designed for metric thread milling in the hardest materials. Built for machinists who demand reliability and repeatable tolerance, these fast-type mills excel where other tools struggle.

• Threading capacity: Metric M5 x 0.8 thread milling capability, enabling standard fasteners and precise threaded features in hard workpieces.
• Material: Solid carbide with MT3 ultra-fine grade for rigid cutting performance and long tool life in demanding materials.
• Coating: PVD multi-layer coating paired with MT3 geometry to maximize heat resistance and wear life when machining superalloys and hard metals (up to 65 HRC).
• Flute count: High flute count (up to 7) for efficient chip evacuation, smoother cutting, and improved rigidity during demanding milling operations.
• Cutting type: Fast Type design optimized for rapid material removal while maintaining accurate thread geometry and surface finish.
• Shank compatibility: MT3 shank compatible with standard toolholding systems for secure fit and minimal runout.

These thread mills deliver reliable, high-precision threading in hardened steels, nickel-based alloys, and other hard materials. The combination of an ultra-fine MT3 carbide, multi-layer PVD coating, and an elevated flute count translates to steadier cuts, better edge stability, and longer life in high-temperature machining scenarios. Ideal for aerospace, mold making, and precision components where consistent thread quality and productivity matter.
