Description

The Carmex Spiral Mill Threading Insert – Whitworth is a versatile, indexable threading solution designed to deliver fast, smooth cuts on Whitworth threads. Built for machine shops, job shops, and manufacturing environments, it supports precise threading and milling operations with fewer passes.

Spiral fluted geometry and a robust clamping system enable high feed rates, reduced cycle times, and reliable indexation. In addition, inserts are MT7 sub-micron grade with a Titanium Nitride multi-layer coating (ISO K10-K20), delivering long wear life and stable performance across a wide range of materials.

  • Smooth, fast cutting with spiral design: The spiral geometry enables smooth cutting at high feed rates, reducing machining time and helping achieve consistent thread quality on Whitworth threads.
  • Flexible insert capacity and precise indexation: Spiral toolholders hold 1 to 9 inserts in a compact cutting diameter, with a unique clamping method that ensures reliable indexability and quick setup.
  • Durable MT7 inserts with TiN coating: MT7 sub-micron grade with TiN multi-layer coating provides long wear life and reliable performance on all materials, suitable for threading, end milling roughing, and finishing.

This combination helps you complete more work per shift, maintain tight tolerances, and reduce tool changes. The Carmex Spiral Mill Threading Insert delivers consistent results, lower downtime, and dependable performance across a wide range of materials and applications.
