Carmex Spiral Mill Finishing Insert - H45FR0.2MT7 is a spiral-fluted finishing insert designed to deliver smooth, efficient cutting across threading, end milling, roughing, and finishing applications. It’s built to handle a wide range of work—from small components on compact machining centers to heavy-duty milling on high-power machines—helping you reduce cycle times without sacrificing quality.

Inserts use MT7 Sub-Micron Grade with Titanium Nitride multi-layer coating (ISO K10-K20), a versatile, general-purpose option that performs across all materials. The spiral design and a unique clamping method enable optimal indexability, while spiral toolholders support 1 to 9 inserts in a compact cutting diameter for flexible setup and quick changes.

• Smooth, high-feed cutting for faster cycles: The spiral geometry enables a smooth cutting action at high feed rates, reducing machining time while maintaining a high-quality finish across threading, end milling, roughing, and finishing.
• Flexible insert capacity with precise indexability: Spiral fluted toolholders hold 1 to 9 inserts in a small cutting diameter, with a unique clamping method that ensures reliable index positioning and straightforward tool changes.
• MT7 TiN-coated inserts for universal material compatibility: Sub-Micron MT7 inserts with Titanium Nitride coating deliver wear resistance and consistent finishes across all materials, while mitigating vibration and chatter for stable performance.

This finishing insert is designed to translate your setup into consistent, reliable results—improving workflow, reducing downtime, and delivering high-grade finishes across a broad range of applications.
