The Carmex Spiral Mill Threading Insert (Unified) H13I14UNMT7 is a versatile spiraled cutting tool designed for threading, end milling, and finishing across a wide range of materials. Built for both precision small-part work on compact machining centers and heavy-duty performance on high-power milling machines, it delivers fast, smooth cutting with fewer passes and lower overall cycle times.

Its spiral geometry and specialized toolholder design allow 1 to 9 inserts to be mounted in a compact cutting diameter, with a unique clamping system that ensures precise, repeatable indexing. This setup minimizes vibration and chatter, helping you achieve consistent finishes whether you’re threading, roughing, or refining the final pass.

• Efficient spiral cutting for faster machining: The spiral flute design enables smooth cutting at high feed rates, reducing cycle times and delivering reliable material removal across a variety of applications.
• Flexible insert capacity with optimized indexing: Toolholders accommodate 1–9 inserts in a compact diameter, and the innovative clamp provides dependable indexability for quick, repeatable insert changes with minimal downtime.
• Durable MT7 Sub-Micron TiN-coated inserts: Sub-Micron Grade inserts with Titanium Nitride multi-layer coating (ISO K10–K20) deliver broad material compatibility, wear resistance, and a consistent finish on threading, roughing, and finishing tasks.

Designed to improve workflow and results, this unified threading insert helps you achieve cleaner threads and smoother surface finishes with fewer passes. Its reliability and versatile performance support tighter tolerances, reduce downtime, and boost overall productivity on both small and demanding milling operations.
