The Carmex Polygon Swiss Line Insert - Grooving - Left Hand - GD25LW17T33BLU is a purpose-built, indexable cutting tool designed for Swiss-type and automatic lathes. Built for high-volume production, it excels in external grooving, back/front turning, profiling, thread turning, parting, and general turning tasks. The left-hand geometry and polygon design deliver precise, reliable performance in demanding Swiss machining environments.

• Grounded cutting edges: Delivers consistent, smooth cuts with longer edge life, reducing chipping and improving surface finish on high-speed grooving and turning.
• Inserts indexed directly on the machine: Enables quick tool changes and minimal downtime, keeping production running smoothly with fewer manual interventions.
• Coated holders provide abrasion resistance: Extends tool life by resisting wear and heat, maintaining stability and accuracy across repeated cycles and tough materials.

This insert is designed to help you accelerate setup, maintain tight tolerances, and achieve repeatable results across a range of Swiss-type operations. Its combination of durable edges, on-machine indexing, and wear-resistant holders supports reliable performance in high-volume production, reducing downtime and rework while delivering consistent productivity and finish quality.
