The Carmex Polygon Swiss Line Insert GT25LG60BLU is a left-hand threading insert designed for Swiss-type machines and automatic lathes. With 60° threading geometry (Partial 60°), it enables precise thread forming while supporting external grooving, back/front turning, profiling, thread turning, parting, and general turning for high-volume production.

In production environments, reliability matters. This insert combines grounded cutting edges for stable, clean cuts and lets you index the inserts directly on the machine, reducing setup time and downtime. The coated holders provide abrasion resistance to stand up to demanding turning tasks.

• Grounded cutting edges: Grounded edges deliver consistent, clean cuts and longer tool life, helping maintain tight tolerances across high-volume runs.
• Inserts indexable directly on the machine: On-machine indexing reduces downtime and speeds tool changes, keeping you productive without removing tools.
• Coated holders for abrasion resistance: Coated holders resist wear and heat, extending tool life and preserving precision through tough turning operations.

This combination supports efficient, repeatable threading and turning workflows on Swiss-type machines, helping you boost throughput, improve surface finish, and lower tooling costs in high-demand manufacturing environments.
