Carmex Swiss Line Insert - Threading (ISO) - Left Hand - GT19L0.75ISOBLU is an indexable threading insert system designed for Swiss-type lathes and automatic lathes. It supports high-volume, cost-efficient machining of external grooving, back and front turning, profiling, thread turning, parting, and general turning—with a specific capability for ISO left-hand threading.

The system uses grounded cutting edges and robust coated holders to deliver reliable performance in demanding production environments, while inserts can be indexed directly on the machine for fast setup and minimal downtime.

• Grounded cutting edges: Deliver consistent, clean cuts with longer edge life and improved surface finish for reliable production runs.
• Direct indexing on the machine: Enables quick tool changes without removing the insert, reducing downtime and boosting throughput on Swiss machines.
• Coated holders with abrasion resistance: Provide durable wear protection, extending tool life in threading and turning applications.

Designed for ISO left-hand threading on Swiss-type machines, this insert delivers reliable, repeatable results across long production runs. The combination of grounded edges, on-machine indexing, and abrasion-resistant coatings helps maintain consistent thread quality, reduces downtime from tool changes, and extends overall tool life—so you can meet tight tolerances while improving throughput.
