The Carmex Spiral Mill Threading Insert for Whitworth threading (H23-11WMT7) is a versatile spiral-fluted solution designed to simplify threading and finishing tasks. It’s suitable for a wide range of machines—from compact machining centers to high-power milling centers—and supports efficient operations across small and large components alike. The system uses MT7 inserts with a sub-micron grade and TiN multi-layer coating for broad material compatibility.
- High-efficiency cutting with spiral design: The spiral geometry enables smooth cutting at high feed rates, reducing cycle times and boosting productivity in threading, end milling roughing, and finishing.
- Flexible insert capacity with precise indexing: Spiral toolholders hold 1 to 9 inserts in a compact cutting diameter, and the unique clamping method ensures optimal indexability for repeatable, consistent results.
- Durable MT7 TiN-coated inserts for universal materials: Sub-Micron MT7 inserts with Titanium Nitride multi-layer coating (ISO K10-K20) deliver wear resistance and reliable finishes across a wide range of materials.
By combining smooth cutting, adaptable indexing, and durable coatings, the Carmex Spiral Mill Threading Insert helps you shorten cycle times, reduce vibration and chatter, and achieve consistent thread quality and surface finishes across diverse applications. This supports faster setup, fewer tool changes, and improved overall workflow on both small and demanding milling tasks.
