The Carmex Spiral Mill Threading Insert - Whitworth - H17-14WMT7 is a versatile, indexable threading insert designed for Whitworth threads across a wide range of machines and materials. Its spiral flute design enables smooth cutting at high feed rates, helping you cut cycle times and boost productivity on both small component runs and heavy‑duty milling operations.

Designed for flexibility, the spiral toolholder accepts 1 to 9 inserts in a compact cutting diameter, with a unique clamping method that ensures precise indexability. The result is reduced vibration and chatter and a consistently high‑quality finish across threading, roughing, and finishing operations. Inserts are MT7 Sub‑Micron Grade with Titanium Nitride multi‑layer coating (ISO K10‑K20), providing broad material compatibility and long wear life.

  • Smooth cutting at high feed rates: Spiral design enables fast, clean cuts with minimized machining time, improving throughput on both small parts and heavy‑duty applications.
  • Flexible insert capacity with precise indexing: Spiral fluted toolholders hold 1–9 inserts in a compact diameter, and the unique clamp ensures reliable, repeatable indexation for consistent results.
  • MT7 TiN-coated inserts for broad material compatibility: Sub‑Micron MT7 inserts with TiN coating deliver enhanced wear resistance and dependable performance across many materials.

This combination supports efficient threading, roughing, and finishing with durable tooling that maintains accuracy and surface quality. Whether you’re optimizing a small shop workflow or running high‑power milling centers, the Carmex spiral system helps reduce downtime, improve thread consistency, and deliver reliable results across diverse materials.
