Description

The Carmex Polygon Swiss Line Insert is a purpose-built, indexable cutting tool designed for Swiss‑type lathes and automatic turning centers. It enables high‑volume, cost‑efficient machining across external grooving, back turning, profiling, thread turning, parting, and general turning applications—delivering consistent results in demanding production environments.

In addition to its versatile geometry, the inserts can be indexed directly on the machine, reducing changeover time and keeping production moving. Grounded cutting edges contribute to clean cuts and reliable performance, while coated holders deliver abrasion resistance to stand up to tough shop floor conditions.

  • On‑machine indexing: Quick insert changes without removing the tool, minimizing downtime and keeping production lines flowing.
  • Grounded cutting edges: Deliver consistent surface finish and predictable tool life for repeatable results.
  • Coated holders for abrasion resistance: Enhance durability and longevity in demanding turning applications.

This combination of versatility, efficiency, and durable construction helps you optimize throughput on Swiss machines, improve part quality, and reduce maintenance costs over the life of the tooling.
