The Carmex Spiral Mill Finishing Insert - H45FR1.5MT7 is a spiral-fluted finishing insert designed for threading, end milling roughing, and finishing. Its compact, multi-insert tool design is ideal for a wide range of machines—from small machining centers to high-power milling centers—delivering smooth cutting at high feed rates and reduced cycle times.

Inserts are MT7 Sub-Micron Grade with Titanium Nitride (TiN) multi-layer coating (ISO K10–K20), offering broad material compatibility and reliable wear resistance for a consistent, high-quality finish across threading and milling operations.

• High-Feed, Smooth Spiral Cutting: The spiral design enables a smooth cutting action at higher feed rates, reducing machining time and improving throughput on both small components and heavy-duty milling tasks.
• Flexible 1–9 Insert Platform with Precise Indexing: Spiral toolholders hold 1 to 9 inserts in a compact cutting diameter, and the unique clamping method ensures optimal indexability for quick, reliable re-indexing with minimal downtime.
• MT7 Sub-Micron TiN-Coated Inserts for Universal Material Compatibility: Sub-Micron MT7 inserts with TiN multi-layer coating (ISO K10–K20) deliver long tool life and consistent finishes across a wide range of materials.

This combination helps you finish threads and profiles with precision, improves workflow by reducing tool changes and setup time, and delivers repeatable results across job types—from precision small-part work to demanding production runs. The Carmex Spiral Mill Finishing Insert provides dependable performance, durable construction, and confidence to push your machining toward higher productivity without sacrificing finish quality.
