Description

Carmex MT thread mills are built for machinists who need reliable internal and external threading with a focus on efficiency and value. This solid carbide tool delivers precise NPT thread milling performance in a compact, easy-to-integrate package.

  • Material: Solid carbide for high rigidity, wear resistance, and long tool life in demanding threading applications.
  • Threading capabilities: Supports internal and external thread milling, including National Pipe Tiping (NPT) threads for pipe fittings and hydraulic components.
  • Flute count: Multi-flute geometry (3–5 flutes) designed to balance cutting action, chip evacuation, and surface finish.
  • Shank: MT7 Morse taper shank for secure seating and compatibility with standard CNC tool holders.
  • Efficiency and reliability: Optimized flute geometry and relief reduce chatter and improve cycle times, delivering consistent thread forms.

This MT line threading solution provides a practical, cost-conscious option for shops needing dependable thread milling that covers both internal and external threads, including NPT, without sacrificing accuracy or finish. Ideal for production runs, repair work, and custom fabrication where precise threaded connections are essential.
