The Carmex Polygon Swiss Line Insert for Grooving & Turning is a left-hand, indexable cutting tool designed for Swiss-type machines and automatic lathes. Built for high-volume production, it enables efficient external grooving, back and front turning, profiling, thread turning, parting, and general turning with repeatable results.

With grounded cutting edges and a durable, coated holder, this insert delivers reliable performance in demanding turning environments while enabling quick on-machine indexing for fast tool changes and minimal downtime.

• Grounded cutting edges: Consistent, clean cuts with reduced edge chipping and longer edge life, helping you maintain tight tolerances and better surface finish.
• On-machine indexing: Rotate to a fresh edge directly on the Swiss machine—no tool removal or rework, reducing setup time and maximizing uptime.
• Abrasion-resistant coated holders: Coatings protect the holder from heat and wear, preserving accuracy and extending tool life in high-speed turning and heavy-duty grooving.

Designed for Swiss-type turning, the Carmex Polygon insert delivers dependable, long-life performance across grooving, profiling, threading, and turning applications. The left-hand geometry ensures proper orientation for your turning operations, while on-machine indexing minimizes downtime and accelerates production. With grounded edges and heat- and wear-resistant coatings, you can maintain consistent diameters, smooth finishes, and lower cost per part in high-volume machining environments.
