Carmex Spiral Mill Threading Insert - Unified - H32I18UNMT7

The Carmex Spiral Mill Threading Insert (Unified) H32I18UNMT7 is a versatile tooling solution designed for both precision small-part work and demanding high-power milling. It combines a spiral-fluted design with an indexable insert system to deliver smooth threading and milling across a wide range of materials.

Engineered to enable higher feed rates and shorter cycle times, this spiral tool reduces vibration and chatter while maintaining a high-quality surface finish on threading, end milling roughing, and finishing operations. It’s suitable for everything from small components on compact machining centers to heavy-duty work on powerful milling machines.

• Spiral geometry for fast, smooth cutting: Enables high feed rates and reduced machining time while maintaining steady cutting action and clean thread surfaces.
• Flexible, indexable inserts with compact diameter: Spiral fluted toolholders hold 1 to 9 inserts in a small cutting diameter, with a unique clamping method that ensures optimal indexability for consistent results.
• Durable MT7 TiN-coated inserts for broad material compatibility: Inserts are MT7 Sub-Micron Grade with Titanium Nitride multi-layer coating (ISO K10-K20), a general-purpose grade usable with all materials, delivering wear resistance and a reliable finish.

This toolset helps you streamline production by delivering reliable, repeatable results across threading and milling tasks. The combination of efficient spiral cutting, adaptable insert indexing, and durable TiN-coated MT7 inserts supports longer tool life, tighter tolerances, and a smoother finish—so you can complete more parts with confidence and minimize downtime.
