Description

The Carmex solid carbide thread mill delivers precise internal and external NPTF threading for 1/2 and 3/4 inch sizes at 14 threads per inch. Built for machinists working in CNC and manual setups, it combines durability with efficient material removal to handle tough threading jobs reliably.

  • Solid Carbide Construction: Provides excellent rigidity and heat resistance during high-speed milling operations on various metals.
  • Multi-Flute Design: Incorporates 3-5 flutes that distribute cutting forces evenly for smoother finishes and reduced cycle times.
  • NPTF Thread Compatibility: Specifically engineered for 1/2 and 3/4 inch dryseal pipe threads, supporting both internal and external profiles in a single tool.
  • MT7 Grade Coating: Enhances wear resistance and extends tool life when machining stainless steel, alloys, and carbon steels.

This thread mill helps reduce tooling costs and setup changes by handling multiple thread sizes and directions with consistent accuracy. Operators gain reliable thread quality on production runs while minimizing chatter and downtime.
