The Carmex Spiral Mill Threading Insert - Metric/ISO - H23E1.0ISOMT7 is a versatile threading and milling solution designed for precision work across a broad range of parts and machines. Whether you’re a design engineer, a shop-floor buyer, or a tradesperson upgrading a compact milling center, this spiral insert system helps you cut threads, rough out features, and finish surfaces with dependable results.

Its spiral geometry reduces cutting forces, enabling higher feed rates and shorter cycle times, while maintaining a smooth, consistent cut. The toolholder family supports 1 to 9 inserts in a compact cutting diameter, and the unique clamping method ensures reliable indexability with minimal downtime. Inserts utilize MT7 sub-micron grade with a Titanium Nitride multi-layer coating (ISO K10-K20), delivering durable performance and a high-quality finish across threading, roughing, and finishing applications.

• Smooth cutting at high feed rates: Spiral design enables efficient cutting with reduced machining time and clean thread finishes.
• Compact, high-indexability insert mounting: 1–9 inserts in a small diameter with a unique clamp for repeatable indexing and minimal tool changes.
• MT7 sub-micron, TiN-coated inserts for all materials: Long wear life and consistent finishes across a wide range of materials, suitable for threading, roughing, and finishing.

By combining the spiral cutting action, flexible insert indexing, and durable MT7 TiN-coated inserts, this system helps you boost throughput, reduce downtime, and achieve reliable, high-quality results on both simple and demanding parts. It’s a practical choice for shops seeking consistent performance, lower rework, and confidence in every part produced.
