The Carmex Spiral Mill Threading Insert (Metric/ISO) is a spiral-fluted cutting tool designed for threading and milling tasks. Built for a wide range of applications, it performs reliably from small components on compact machining centers to heavy-duty work on high-power milling machines. The tool accepts 1 to 9 inserts in a compact cutting diameter, offering flexible configuration for different jobs.

• Smooth, high-feed cutting: The spiral mill-thread design enables smooth cutting at high feed rates, reducing machining time and boosting overall productivity.
• Versatile, wide-range applications: Suitable for small component work on compact centers and tough tasks on powerful mills, delivering consistent results across threading, roughing, and finishing.
• Reliable indexing with durable inserts: A unique clamping method provides optimal indexability, while MT7 Sub-Micron TiN-coated inserts (ISO K10-K20) offer wear resistance and broad material compatibility for longer tool life.

In use, this insert helps you speed up cycles without sacrificing finish quality. The combination of spiral geometry, flexible insert count (1–9), and robust coatings supports dependable performance across materials and applications, making it a practical choice for shops aiming to improve throughput, reduce downtime, and achieve repeatable, high-quality results.
