Description
The Carmex Swiss Line Insert - Threading (UN) - Left Hand - GT19L20UNBLU is a precision indexable tool 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, helping shops increase throughput without sacrificing quality.
Designed for left-hand UN threading, this insert pairs with standard holders and lets you index inserts directly on the machine, simplifying setup and minimizing downtime in tight production schedules.
- Direct indexing on the machine: Quick, tool-free insert changes reduce setup time and downtime, keeping your production running smoothly.
- Grounded cutting edges: Consistent, clean cuts with reliable performance across high-speed turning and threading operations.
- Coated holders provide abrasion resistance: Enhanced wear and heat resistance extend tool life in demanding Swiss-type and automatic lathe environments.
This combination delivers dependable, repeatable results across jobs, helping you improve workflow, reduce tool costs, and maintain high-quality threads and profiles on every part.
