Designed for Swiss-type lathes and automatic turning centers, the Carmex Swiss Line Insert - Threading (ISO) - Left Hand is a high-performance left-hand threading insert engineered for ISO-threading and demanding production runs. It enables fast, reliable thread turning, profiling, and turning across high-volume applications while simplifying setup and maintaining consistent results on Swiss machines.

• Grounded cutting edges: Precision-ground edges deliver clean starts and consistent thread quality, helping extend tool life even on tough materials.
• In-machine indexing: The insert can be indexed directly on the machine, reducing downtime and keeping production flowing with quick edge refreshes.
• Coated holders for abrasion resistance: Coatings on the holder resist wear, protecting both insert and tooling assembly during demanding threading and turning passes.

This combination supports high-volume, cost-efficient operations for external grooving, back/front turning, profiling, thread turning, parting, and general turning tasks. With its left-hand threading capability and robust, easy-to-use design, it helps teams achieve reliable, repeatable results, shorten setup times, and maintain steady throughput across ISO-threading projects.
