Carmex Polygon Swiss Line Insert – Threading (ISO) – Left Hand is a purpose-built, indexable cutting solution for Swiss-type machines and automatic lathes. It enables high-volume, cost-efficient external threading and related turning operations, making it ideal for shops running long production runs or parts with tight tolerances.

Designed to keep production flowing, this tool family features grounded cutting edges and inserts that can be indexed directly on the machine, reducing setup time. Coated holders provide abrasion resistance to help extend tool life in demanding threading work.

• Directly indexed inserts on the machine: Speeds setup and minimizes downtime by allowing quick insert changes without removing tooling, boosting throughput on Swiss-type and automatic lathe operations.
• Grounded cutting edges for consistent results: Delivers reliable, clean thread starts and stable performance, helping to reduce rework and maintain tight dimensional control.
• Abrasion‑resistant coated holders: Extends tool life in tough threading jobs, lowering replacement costs and downtime while maintaining precision across production runs.

Designed for high-volume, cost-efficient threading and turning applications, this insert supports reliable ISO left-hand threading and a range of turning tasks on Swiss-type machines. The combination of on-machine indexing, grounded edges, and abrasion-resistant coatings helps you shorten setup times, improve part quality, and keep production moving smoothly from run to run.
