The Carmex Spiral Mill Threading Insert - Unified - H15I14UNMT7 is a spiral threading insert designed for engineers, machinists, tradespeople, hobbyists, and buyers who demand fast, reliable threading and milling performance.
The system delivers smooth cutting at high feed rates and helps reduce overall machining time, making it suitable for everything from small components on compact machining centers to heavy-duty work in high-power milling machines.
- Smooth, high-feed cutting: Spiral design enables a smooth cutting operation at a high feed rate, reducing machining time and improving throughput.
- Flexible, indexable insert design: Spiral fluted toolholders hold 1 to 9 inserts in a small cutting diameter, and a unique clamping method enables optimal indexability.
- Coated MT7 inserts for broad material compatibility: Sub-Micron MT7 grade with Titanium Nitride multi-layer coating (ISO K10–K20) provides versatility across materials and helps achieve consistent finishes in threading, end milling, roughing, and finishing.
This combination of spiral cutting action, adjustable insert count, and TiN-coated MT7 inserts translates into faster cycles, reduced vibration and chatter, and a consistently high-quality finish across threading, end milling, roughing, and finishing tasks. The MT7 general-purpose grade provides broad material compatibility, usable with all materials, to deliver reliable, repeatable results across a wide range of applications.
