Description
The Carmex Polygon Swiss Line Insert for threading (UN) – Left Hand, GT25L24UNBLU, is a purpose-built indexable insert designed for Swiss-type lathes and automatic turning centers. It enables high-volume, cost-efficient external grooving, back/front turning, profiling and thread turning with consistent results and long tool life.
- Grounded cutting edges: Maintains sharpness for clean, precise cuts and extended tool life across threading, profiling and turning operations.
- In-machine indexing: Inserts can be indexed directly on the machine, reducing setup time and minimizing downtime between jobs while preserving accuracy.
- Coated holders for abrasion resistance: Durable coatings protect the tool assembly in tough materials and high-volume cycles, helping maintain tolerance and surface finish over long production runs.
This combination provides a reliable, efficient threading and turning solution for Swiss-type equipment, helping you reduce tool changes, improve process consistency, and achieve high-quality parts quickly—whether you’re producing threads, grooves, or complex profiles on demanding components.
