Description
Carmex Polygon Swiss Line Insert - Threading (UN) - Left Hand - GT25L56UNBLU is an indexable cutting insert designed for Swiss-type machines and automatic lathes. Built to handle UN-threading and related turning tasks, it enables high-volume, cost-efficient production with quick, on-machine indexing.
- Grounded cutting edges: Delivers stable, precise cuts with consistent geometry, helping you achieve reliable thread profiles and smooth finishing across long runs.
- Direct on-machine indexing: Inserts can be indexed without removing the tool, reducing setup time and minimizing downtime for faster, more predictable production cycles.
- Coated holders provide abrasion resistance: The coated interface shields the holder from wear and heat, extending tool life and sustaining accuracy in demanding materials and environments.
This insert supports efficient UN-threading on Swiss-type machinery while delivering durable performance and dependable results. By combining quick indexing, stable cutting edges, and abrasion-resistant holders, it helps improve workflow consistency, reduce maintenance intervals, and boost overall turning productivity.
