The Carmex Spiral Mill Threading Insert (Unified) H32I20UNMT7 is a versatile spiral milling tool designed for threading and precision milling. It suits a wide range of machines—from compact machining centers to high-power mills—delivering fast, smooth cuts with reduced cycle times. The spiral design minimizes cutting resistance, helping you achieve efficient material removal and cleaner threads across various applications.

• Flexible insert capacity with precise indexing: Spiral fluted toolholders accommodate 1 to 9 inserts in a compact cutting diameter, and a unique clamping method ensures optimal indexability for quick, reliable setups and consistent results.
• Fast, smooth threading with reduced cycle time: The spiral geometry enables a smooth cutting action at high feed rates, reducing machining time while maintaining stability and minimizing vibration and chatter.
• Durable coating for universal material compatibility: Inserts use MT7 Sub-Micron Grade with Titanium Nitride multi-layer coating (ISO K10-K20), delivering wear resistance and reliable performance for threading, end milling roughing, and finishing on all materials.

Designed for reliability in demanding workloads, this insert system helps you maintain accuracy, reduce tool changes, and improve throughput. Its combination of robust construction, advanced coating, and flexible indexing supports consistent finishes and dependable performance—from precise threads to roughing passes—across a wide range of materials and applications.
