The Carmex Swiss Line Insert - Threading (ISO) - Left Hand - GT19L1.0ISOBLU is an indexable cutting tool designed for Swiss-type machines and automatic lathes. It’s purpose-built for ISO threading and supports high-volume, cost-efficient machining of external grooves, back/front turning, profiling, thread turning, parting, and general turning—delivering reliable performance in demanding production environments.

Grounded cutting edges, direct on-machine indexing of the inserts, and coated holders with abrasion resistance work together to deliver consistent, productive results. This combination is engineered to reduce downtime, extend tool life, and maintain precision across long runs.

• Direct on-machine indexing: enables quick insert changes on the Swiss machine itself, minimizing setup time and maximizing uptime during threading and turning operations.
• Grounded cutting edges: provide stable geometry for accurate threads and smooth finishes, helping to maintain tight tolerances pass after pass.
• Coated holders for abrasion resistance: resist wear in tough materials, extending tool life and delivering dependable performance across shifts.

Designed for left-hand ISO threading on Swiss-type equipment, this insert helps you accelerate production, improve workflow efficiency, and achieve reliable, repeatable threading results with every part.
