The Carmex Spiral Mill Threading Insert is a metric/ISO cutting solution designed for precision threading and milling. Its spiral geometry delivers smooth cutting and high feed rates, helping you complete jobs faster with consistent results.
It suits a wide range of applications—from small component work on compact machining centers to heavy-duty milling on high-power machines. The spiral fluted toolholders hold 1 to 9 inserts in a comparatively small cutting diameter, and the unique clamping method ensures optimal indexability while reducing vibration for reliable threading, roughing, and finishing—across a broad set of materials.
- High-Performance Spiral Cutting: Smooth cutting at high feed rates reduces machining time and minimizes vibration and chatter, delivering consistent finishes in threading and milling.
- Flexible 1–9 Insert Tooling in a Compact Diameter: Spiral fluted toolholders accommodate 1 to 9 inserts in a small cutting diameter, boosting productivity with more inserts per tool and fewer tool changes.
- MT7 Sub-Micron TiN-Coated Inserts: Inserts feature MT7 sub-micron grade with a TiN multi-layer coating (ISO K10‑K20), providing wear resistance and broad material compatibility for reliable performance.
This combination helps you speed production while maintaining quality: faster cycles, fewer tool changes, and repeatable, high-quality finishes in threading, roughing, and finishing tasks. Whether you’re threading small components on a compact machine or tackling demanding milling on a high-power setup, you can rely on the Carmex Spiral Mill Threading Insert for durable performance and consistent results.
