Carmex Spiral Mill Threading Insert - Metric/ISO - H17I1.5ISOMT7

The Carmex Spiral Mill Threading Insert is a metric/ISO threading tool designed for a wide range of milling and threading tasks. Its spiral geometry delivers smooth cutting at high feed rates, helping reduce cycle times and increase overall throughput. Built for both compact milling centers and high‑power machines, it uses spiral fluted toolholders that can hold 1 to 9 inserts in a compact cutting diameter, with a unique clamping method that ensures reliable indexing and minimizes vibration across threading, roughing and finishing operations. The insert system is specified for metric/ISO use, including H17I1.5 geometry, and pairs with MT7 inserts for versatile performance.

• Smooth, high‑feed cutting: The spiral design enables fast material removal with a refined finish, cutting machining time across threading, end milling, roughing and finishing tasks.
• Flexible, indexable insert capacity: Spiral fluted toolholders accommodate 1–9 inserts in a compact diameter, with a clamping system that supports precise, reliable indexing for quick tool setups and consistent results.
• MT7 Sub‑Micron TiN coated inserts: Inserts use MT7 Sub‑Micron Grade with a multi‑layer Titanium Nitride coating (ISO K10–K20), a general‑purpose solution that delivers wear resistance and compatibility with a wide range of materials.

This toolset enables you to achieve reliable, repeatable threading and milling results with fewer tool changes and smoother operation. The combination of spiral geometry, versatile insert capacity, and durable MT7 TiN‑coated inserts supports efficient production workflows, tighter tolerances, and consistent surface finishes across different materials and machining scenarios.
