Description

The Carmex Spiral Mill Threading Insert for Whitworth threads is a versatile precision tooling solution designed for engineers, machinists, and fabricators. It enables smooth, high-feed cutting across a wide range of applications—from small-component work on compact machining centers to heavy-duty milling on high-power machines—delivering reliable threading and efficient material removal. The spiral design and dedicated toolholders support 1 to 9 inserts in a compact cutting diameter, helping you maintain tight tolerances with minimal setup.

  • Smooth, high‑feed cutting with reduced cycle times: The spiral mill-threading design delivers clean cuts at high feed rates, helping you finish more parts per shift with less machining time.
  • Compact, indexable insert system with stable clamping: Spiral fluted toolholders hold 1–9 inserts in a small cutting diameter, and a unique clamping method ensures optimal indexability while minimizing vibration and chatter.
  • Durable MT7 TiN-coated inserts for universal use: MT7 Sub-Micron Grade with Titanium Nitride multi‑layer coating (ISO K10‑K20) provides a general‑purpose solution that performs across a wide range of materials, delivering consistent finishes in threading, roughing, and finishing.

This tool empowers you to achieve reliable Whitworth threading and quality milling finishes with predictable performance, reducing downtime and enabling smoother workflows across diverse machines and production needs.
