The Carmex Spiral Mill Threading Insert (Metric/ISO) is a versatile threading and milling solution designed for a wide range of jobs—from precise small-part work on compact centers to heavy-duty tasks on high-power machines. Its spiral design delivers a smooth cut at high feed rates, helping you reduce machining time while maintaining accuracy. The spiral fluted toolholder accommodates 1 to 9 inserts in a compact diameter, with a unique clamping method that ensures optimal indexability and minimizes vibration and chatter for a consistent, high-quality finish. Inlays use MT7 Sub-Micron Grade with a Titanium Nitride multi-layer coating (ISO K10–K20), a general-purpose grade designed to perform well with all materials.

• Holds 1–9 inserts in a compact diameter: Spiral fluted toolholders accommodate 1 to 9 inserts in a comparatively small cutting diameter, enabling flexible threading and milling without bulky tooling.
• Unique clamping for optimal indexability: The specialized clamping method ensures precise and repeatable insert positioning, supporting reliable indexing and reducing setup time.
• MT7 Sub-Micron TiN-coated inserts for broad material compatibility: The MT7 Sub-Micron Grade with Titanium Nitride multi-layer coating (ISO K10–K20) delivers consistent performance across materials with improved wear resistance.

This combination helps you speed up production cycles, achieve smooth, accurate threads and finished surfaces, and minimize downtime caused by tool changes or unpredictable performance. The spiral geometry reduces chatter for stable cutting on a range of materials, while the TiN-coated MT7 inserts provide dependable, versatile performance across threading, roughing, and finishing tasks. For shops seeking efficient setups, repeatable results, and a single, high-coverage solution, this insert delivers dependable performance across the job spectrum.
