Description

Designed for Swiss-type lathes and automatic turning centers, the Carmex Swiss Line Insert for Parting Off – Left Hand (GP19LNW12T54BLU) enables fast, repeatable parting-off and turning in high-volume production. It is optimized for left-hand Swiss operations and supports external grooving, profiling, thread turning, and general turning with reliable results on demanding materials.

  • On-Machine Indexing: Inserts can be indexed directly on the Swiss-type machine, enabling quick tool changes and reducing downtime on high-volume cycles.
  • Grounded Cutting Edges: Precision-ground edges provide clean, consistent cuts and stable geometry for reliable parting-off and turning, improving surface finish and part accuracy.
  • Abrasion-Resistant Coated Holders: Coated holders resist wear and heat, extending tool life and maintaining performance in challenging materials and long production runs.

This insert delivers a dependable, efficient solution for high-volume Swiss machining. Quick on-machine indexing reduces downtime, the grounded edges ensure consistent finishes, and the abrasion-resistant coatings on the holders help lower replacement costs and keep production moving. Ideal for external grooving, back/front turning, profiling, thread turning, parting, and general turning tasks, it helps you improve part quality, shorten cycle times, and maintain tight tolerances across demanding materials.
