The Carmex Spiral Mill Threading Insert - Metric/ISO - H45I4.5ISOMT7 is a modular spiral milling solution designed for ISO metric threading. Whether you’re producing small components on compact machining centers or tackling heavy‑duty work on high‑power milling machines, this tool delivers fast, smooth cutting with reduced machining time.

Spiral fluted tool holders accommodate 1 to 9 inserts in a compact cutting diameter, enabling efficient insert indexing. A unique clamping method ensures optimal indexability, while the spiral geometry minimizes vibration and chatter to deliver a high‑quality finish across threading, end milling roughing, and finishing tasks. Inserts are MT7 Sub‑Micron Grade with Titanium Nitride multi‑layer coating (ISO K10‑K20), a general‑purpose grade that can be used with all materials.

• High‑feed, smooth threading: Spiral design enables smooth cutting at high feed rates, reducing cycle times and boosting productivity across a range of machines.
• 1–9 inserts in a compact diameter: Flexible insert capacity with a unique clamping system provides reliable indexability and quick, precise insert changes for consistent results.
• MT7 TiN‑coated universal inserts: Sub‑Micron MT7 inserts with TiN multilayer coating offer wear resistance and broad material compatibility, delivering durable performance and a high-quality finish.

Designed for reliable performance in both delicate, small‑component work and demanding, high‑power milling environments, this spiral milling solution helps you shorten setup and cycle times, maintain consistent thread quality, and achieve superior surface finishes across materials.
