The Carmex Spiral Mill Threading Insert (Unified) H23E7UNMT7 is a versatile threading and finishing tool designed for a broad range of milling tasks. It shines on everything from small components in compact machining centers to heavy-duty work on high-power mills, delivering smooth cutting at high feed rates and shorter cycle times for increased productivity.

• High-efficiency spiral cutting: The spiral flute design enables smooth, chatter-free cutting at high feed rates, reducing overall machining time without sacrificing finish or tolerance.
• Flexible insert indexing with compact holder: Toolholders support 1–9 inserts in a small cutting diameter, with a unique clamping method that ensures optimal indexability and minimizes downtime during insert changes.
• MT7 TiN-coated inserts for all materials: Inlays use MT7 sub-micron grade with a TiN multi-layer coating (ISO K10–K20), providing reliable wear resistance and consistent threading, roughing, and finishing across a wide range of materials.

This combination helps you achieve reliable, repeatable results with a smoother workflow. Faster material removal, reduced vibration, and long-lasting inserts translate to fewer tool changes, steadier finishes, and improved overall performance on both small-part and demanding machining jobs.
