Description

The Carmex Polygon Swiss Line Threading Insert (Partial 60°, Left Hand) GT25LA60BLU is a purpose-built tool insert for Swiss-type lathes and automatic turning centers. Designed for a wide audience—from engineers and buyers to tradespeople, hobbyists, and non-technical users—it enables high-volume, cost-efficient machining across threading, external grooving, back/front turning, profiling, parting, and general turning.

  • Grounded cutting edges: Precisely formed edges provide stable, consistent cuts and longer insert life in demanding materials and applications.
  • Direct indexing on the machine: Inserts can be indexed directly on the machine, reducing setup time and downtime by avoiding tool removal or re-zeroing.
  • Abrasion-resistant coated holders: The coated holders resist wear in tough environments, helping maintain accuracy and extend tool life for reliable performance.

By integrating these features, the insert supports repeatable threading and turning results on Swiss-type machines, helping you streamline workflows, minimize downtime, and deliver consistent quality across production runs.
