Carmex Spiral Mill Threading Insert - Metric/ISO - H45I3.5ISOMT7

The Carmex Spiral Mill Threading Insert is a metric/ISO threading solution built for versatility and productivity. Designed for a wide range of machining tasks, its spiral cutting action enables smooth operation at high feed rates, helping you complete threads and milling work faster without sacrificing accuracy. Whether you’re producing small components on compact centers or tackling heavy-duty milling on high-power machines, this insert is engineered to boost throughput.

Spiral fluted toolholders accommodate 1 to 9 inserts in a compact cutting diameter, and a unique clamping method ensures optimal indexability. This design minimizes vibration and chatter, delivering a consistent, high-grade finish across threading, end milling roughing, and finishing operations. Inserts are MT7 Sub-Micron Grade with Titanium Nitride multi-layer coating (ISO K10-K20), a general-purpose option that performs reliably with all materials.

• Smooth, high‑throughput cutting: The spiral design enables smooth cutting at high feed rates, reducing machining time while maintaining precise thread quality.
• Flexible insert array with precise indexability: Toolholders hold 1–9 inserts in a small cutting diameter, with a unique clamp that ensures reliable indexability and reduced vibration for stable cuts.
• MT7 TiN-coated inserts for universal performance: Sub-Micron MT7 grade with TiN multi-layer coating delivers durable wear resistance and versatile performance across threading, roughing, and finishing for all materials.

This setup helps you streamline workflows, minimize downtime from tool changes, and consistently achieve accurate threads and clean finishes. With reliable indexing, durable coatings, and a design tuned for both light and heavy milling, it’s a dependable choice for engineers, shop floor technicians, and hobbyists aiming for predictable, high-quality results.
