The Carmex Polygon Swiss Line Insert – Grooving & Turning, Left Hand – G25LW10T27BLU is a purpose-built, indexable tool for Swiss-type and automatic lathes. Designed for high-volume production, it enables precise external grooving, front and back turning, profiling, thread turning, parting, and general turning with a single, versatile insert system. This left-hand version is optimized for the common geometries found on Swiss machines, helping you achieve consistent results across multiple parts and runs.

• Grounded cutting edges: Delivers stable, smooth cuts with reduced chatter, producing uniform surface finishes and longer insert life even under demanding cutting conditions.
• Inserts indexable directly on the machine: Minimizes downtime by allowing quick tool changes without removing the holder, keeping production flowing and part queues shorter.
• Coated holders provide abrasion resistance: Extends tool life in high-wear environments and maintains close tolerances by resisting heat and wear during aggressive turning and grooving.

This tool supports fast setup, reliable performance, and consistent part quality across a range of Swiss machining tasks. By combining left-hand geometry with a robust, indexable insert system, it helps shops improve throughput, reduce part costs, and sustain precise results from first part to last.
