The Carmex Swiss Line G6 Insert is a partial-profile threading insert engineered for machining external threads. Specifically designed for left-hand UN threads, it uses six cutting edges to deliver fast, reliable threading with excellent cost efficiency.

Built to accommodate a wide range of diameters—from small, thin-walled parts up to 60 mm—the G6 family is a versatile choice for job shops, OEMs, and maintenance teams tackling diverse threading tasks.

• Six Cutting Edges for High Productivity and Cost-Effectiveness: The six usable edges allow quick indexing to a fresh edge, reducing insert changes and improving cycle times while maintaining consistent thread quality.
• Broad Diameter Range: Compatible with a wide spectrum of diameters—from very small, thin-walled sections to up to 60 mm—minimizing tool changes and expanding manufacturing flexibility.
• Left-Hand UN Threading Ready: Precisely engineered for external left-hand UN threads, providing reliable geometry and finish on every pass.

This insert helps you streamline threading workflows by delivering consistent, accurate external left-hand UN threads across a broad range of part sizes. Its multiple cutting edges extend tool life, reduce downtime between changes, and simplify inventory by covering many diameters with a single insert family. Built for reliability and steady performance, it supports on-time production, tighter tolerances, and better overall results on challenging threading tasks.
