The Carmex Polygon Swiss Line Insert - Threading (ISO) - Left Hand - GT25L0.6ISOBLU is a left-hand ISO threading insert designed for Swiss-type machines and automatic lathes. It enables high-volume, cost-efficient machining of external grooving, back/front turning, profiling, thread turning, parting, and general turning applications, making it a versatile choice for precision production environments.

Grounded cutting edges deliver stable, precise cuts and repeatable finishes, helping you achieve consistent threading and turning results across batches. The inserts can be indexed directly on the machine, simplifying changeovers and reducing downtime. Coated holders provide abrasion resistance, extending tool life and maintaining performance in demanding cutting conditions.

• Grounded cutting edges: Provide stable, precise cuts and repeatable finishes for reliable threading and turning in Swiss-type operations.
• Direct machine indexing: Enables quick, on-machine index changes, reducing setup time and minimizing downtime.
• Abrasion-resistant coated holders: Extend tool life and maintain sharpness under tough cutting conditions, lowering replacement costs.

Designed for high-volume production, this insert supports efficient left-hand threading and general turning on Swiss-type setups, helping you achieve consistent quality, faster cycle times, and lower overall tooling costs over the life of the tool.
