The Carmex Spiral Mill Threading Insert - Unified - H23I18UNMT7 is a spiral-fluted insertion system designed for versatile threading, end milling roughing, and finishing tasks. It’s built to perform on everything from small components on compact machining centers to demanding production on high-power milling machines, delivering smooth cutting and shorter cycle times through its spiral geometry.

  • Spiral Geometry for Fast, Smooth Cutting: Enables high feed rates with a smooth cutting action, helping you reduce cycle times and increase productivity across threading, roughing, and finishing operations.
  • Reliable Indexing with a Unique Clamping System: The design supports 1 to 9 inserts in a compact cutting diameter and uses a clamping method that ensures precise, repeatable indexing for consistent results and easy setup.
  • MT7 Sub-Micron Grade with TiN Coating: Sub-Micron MT7 inserts with Titanium Nitride multi-layer coating (ISO K10-K20) deliver durable wear resistance and broad material compatibility for reliable performance across applications.

This combination provides a versatile, dependable solution that helps you speed up throughput, maintain tight tolerances, and achieve consistent finishes across threading, end milling roughing, and finishing tasks. With durable coatings and a design focused on stable indexing, you can trust it to perform reliably in a wide range of materials and production environments.
