The Carmex Spiral Mill Threading Insert for Whitworth threading (H19-14WMT7) brings spiral milling efficiency to your workshop. Designed for Whitworth threads, it uses MT7 sub-micron inserts with a Titanium Nitride multi-layer coating to deliver durable, consistent cutting across a range of materials. The spiral geometry supports a smooth cutting operation at high feed rates, helping reduce overall machining time.

Built for versatility, this system supports everything from precision small-component work on compact machines to heavy-duty milling on high-power rigs. Spiral fluted toolholders hold 1 to 9 inserts in a comparatively small cutting diameter, and the unique clamping method enables optimal indexability. The result is less vibration and chatter and a high-grade finish in threading as well as roughing and finishing end milling.

• Smooth, high-speed cutting: Spiral mill-thread tools deliver a smooth cutting operation at high feed rates, reducing machining time and boosting throughput.
• Wide application range with compact, indexable inserts: From small-component work on compact centers to heavy-duty milling; spiral toolholders hold 1–9 inserts in a small diameter, with a unique clamp enabling optimal indexability.
• Durable MT7 inserts with TiN coating: Sub-micron MT7 inserts with Titanium Nitride multi-layer coating (ISO K10-K20) provide wear resistance and broad material compatibility for threading and milling.

With these capabilities, the Carmex Spiral Mill Threading Insert helps you complete threading and milling tasks more efficiently, achieve consistent results, and maintain productive uptime across a variety of materials and workpieces.
