Carmex Spiral Mill Threading Insert - Unified - H45I16UNMT7

The Carmex Spiral Mill Threading Insert – Unified – H45I16UNMT7 is a spiral-fluted tool system engineered for threading, end milling, roughing, and finishing. Its spiral design enables a smooth cutting operation at high feed rates, helping to shorten machining times and deliver reliable, repeatable results. The tooling accepts 1 to 9 inserts in a comparatively small cutting diameter, and the unique clamping method provides precise, repeatable indexation across inserts.

Inserts are available in MT7 Sub-Micron Grade with a Titanium Nitride multi-layer coating (ISO K10-K20). This general-purpose grade is designed to perform across a wide range of materials, delivering durable performance and consistent finishes.

• Smooth, high‑feed spiral cutting: The spiral geometry enables efficient material removal with reduced cutting forces, helping you finish jobs faster while maintaining clean, precise threads and surfaces.
• Flexible indexing with compact diameter: 1 to 9 inserts can be mounted in a small cutting diameter, and the unique clamping method ensures optimal indexability, reducing downtime and delivering repeatable results across multiple passes.
• MT7 TiN-coated inserts for durability: Sub-Micron MT7 inserts with a TiN multi-layer coating (ISO K10‑K20) provide long tool life and consistent finishes on a wide range of materials, from soft alloys to harder steels.

This setup supports efficient workflows on both small machining centers and high‑power milling machines, helping you achieve reliable threading, smooth roughing, and high-quality finishing in a single tooling system. With the Carmex Spiral Mill Threading Insert, you gain predictable performance, fewer tool changes, and better surface quality—delivering confidence from setup to part completion.
