Introducing the Carmex MT Thread Mills — a solid carbide tool designed for precise internal and external thread milling on metal parts. It's built for machinists and machine shops seeking reliable, cost-efficient threading solutions.

  • Material: Solid carbide construction delivers high rigidity, wear resistance, and long tool life in demanding threading operations.
  • Threading capability: Internal and external thread milling in a single tool, reducing setup changes and increasing productivity.
  • Thread standards: Optimized for G (55°) thread profiles, including G1/2 and G7/8 x 14, with compatibility for BSF and BSP threading where applicable.
  • Flute design: Multi-flute geometry (3–5 flutes) enhances precision, improves chip evacuation, and yields consistent thread formation.
  • Shank interface: MT7 Morse taper shank provides secure mounting in compatible milling machines and holders.
  • Efficiency: Part of the MT line, engineered for fast, cost-effective threading with reliable repeatability across jobs.
  • Application scope: Ideal for metal components across maintenance, small-batch production, and precision threading tasks needing standard G-thread profiles.

This tool enables you to produce clean, accurate threads with fewer passes, helping to reduce cycle times and tooling costs. The carbide construction maintains sharpness through multiple jobs, delivering consistent results on materials typically machined with G-thread profiles. With MT7 compatibility, it fits a wide range of CNC machines, simplifying integration into existing workflows. Start with conservative speeds and feeds, then optimize for material, thread depth, and finish to maximize tool life and thread quality.
