The Carmex Swiss Line Insert for Parting Off, Left Hand (GP20LLW30T64BLU) is a purpose-built indexable tooling solution designed for Swiss-type and automatic lathes. It enables high-volume, cost-efficient machining of external grooving, back and front turning, profiling, threading, parting, and general turning applications—delivered in a compact, easy-to-index package that keeps production moving.

This insert family is engineered for reliability in demanding production environments. It features grounded cutting edges for consistent, precise cuts and a predictable surface finish. In addition, the inserts can be indexed directly on the machine, simplifying tool changes and reducing setup time. The coated holders add abrasion resistance, helping extend tool life and maintain performance across long runs.

• Grounded cutting edges: Delivers stable, accurate cuts with a smooth finish and repeatable results, reducing rework and improving part quality.
• Direct machine indexing: Enables quick insert changes without removing the tool, minimizing downtime and keeping cycles running at full tempo.
• Coated holders for abrasion resistance: Shields the tool from wear and heat, extending life on tough materials and high-volume workloads.

Designed to integrate seamlessly into Swiss-type workflows, this insert helps you achieve reliable parting off and turning performance with consistent results, faster setups, and longer tool life—so your production stays efficient from the first part to the last.
