Carmex Spiral Mill Threading Insert - Metric/ISO - H32I2.0ISOMT7 is a versatile spiral threading and milling system designed for a wide range of applications. It suits everything from precision small-component work on compact machining centers to heavy-duty milling on high-power machines. The spiral geometry enables smooth cutting at high feed rates and reduced machining time, while MT7 Sub-Micron Grade inserts with Titanium Nitride multi-layer coating (ISO K10-K20) provide dependable performance across materials. This is a general-purpose grade that can be used with all materials.

With 1 to 9 inserts in a compact cutting diameter and a unique clamping method that ensures optimal indexability, you get consistent finishes, easy setup, and flexible coverage for threading, roughing, and finishing in a single tool solution.

• High-efficiency spiral design: The spiral geometry enables smooth cutting at high feed rates, reducing cycle times and boosting throughput on everything from small features to demanding milling tasks.
• Flexible 1–9 insert toolholding with optimal indexability: Spiral fluted toolholders accommodate 1 to 9 inserts in a compact cutting diameter, with a unique clamping method that ensures quick, precise indexing and consistent results.
• MT7 TiN-coated inserts for universal material compatibility: Inserts are MT7 Sub-Micron Grade with Titanium Nitride multi-layer coating (ISO K10-K20), delivering durability and broad material applicability for threading, roughing, and finishing.

This tooling setup helps you finish more work in less time with predictable results. The combination of smooth cutting, flexible insert capacity, and robust coatings translates into fewer tool changes, reduced downtime, and a steady path to tighter tolerances and better surface finishes—whether you’re producing small, intricate parts or tackling larger, high-power milling operations.
