Carmex Spiral Mill Threading Insert - Unified - H32I5UNMT7 is a versatile spiral milling insert designed for threading and finishing passes across a wide range of metals. Built for engineers, machinists, and shop floor teams, it delivers fast material removal with repeatable, high-quality results in both small and high-power milling setups.

The spiral geometry enables smooth cutting at high feed rates, helping to reduce cycle times without sacrificing finish. Spiral-fluted toolholders hold 1 to 9 inserts in a compact cutting diameter, while a unique clamping method ensures optimal indexability for consistent, reliable results on every pass. In MT7 Sub-Micron Grade with Titanium Nitride multi-layer coating (ISO K10–K20), these inserts are designed for durable wear and a superior finish on threading, roughing, and finishing tasks.

• Spiral design for fast, smooth cutting: Delivers high feed rates and reduced machining time while maintaining a clean, finished profile across threading and milling operations.
• Flexible insert capacity with precise indexing: Toolholders accommodate 1–9 inserts in a small cutting diameter, with a unique clamp that delivers reliable indexability and repeatable results.
• MT7 Sub-Micron TiN-coated inserts for universal use: Sub-micron MT7 grade with TiN multi-layer coating provides long wear life and consistent finishes on a wide range of materials (ISO K10–K20).

This combination offers a dependable, adaptable threading and milling solution that helps reduce downtime, improve surface finish, and boost productivity across light-duty to heavy-duty applications. The unified insert system delivers consistent performance, easy setup, and broad material compatibility, making it a solid choice for shops and manufacturers seeking reliable, repeatable results.
