The Carmex Spiral Mill Threading Insert – Metric/ISO (H45I6.0ISOMT7) is a precision spiral milling insert system designed for MT7 tooling. It combines threading and end-milling capability in a compact, indexable format, ideal for a wide range of machines and operators.

Designed to handle everything from tiny components on small CNCs to heavy-duty work on high-power milling centers, the spiral flute design delivers smooth cutting at high feed rates, lowering cycle times and reducing vibration. The holder supports 1 to 9 inserts in a small cutting diameter and uses a unique clamping method to ensure optimal indexability and repeatable results across passes.

• Smooth cutting at high feed rates: The spiral geometry reduces cutting forces and chatter, delivering a cleaner finish and shorter machining times across threading, roughing, and finishing passes.
• Flexible insert configuration with reliable indexability: Spiral toolholders hold 1–9 inserts in a compact cutting diameter, and the unique clamping method ensures consistent index positions for repeatable results with quick setup.
• MT7 Sub-Micron TiN-coated inserts for broad material compatibility: General-purpose ISO K10–K20 coating delivers wear resistance and long tool life across all materials, with a high-grade finish on threading and milling.

With this system, you gain faster throughput, consistent threading quality, and reliable performance across a wide range of parts and materials. The combination of spiral geometry, indexed inserts, and a TiN-coated MT7 grade provides a durable solution that lowers downtime, reduces tool changes, and delivers predictable results from first cut to finish pass. Ideal for shops that run small precision components as well as high-volume production on powerful milling centers.
