Description
The Carmex Polygon Swiss Line Insert - Threading (Partial 55°) - Left Hand is a precision, left‑hand threading insert designed for Swiss‑type and automatic lathes. Built for high‑volume, cost‑efficient turning, threading, grooving, profiling, and parting, it helps shops tackle complex parts with fewer tool changes.
- Grounded cutting edges: Delivers consistent, clean cuts and helps maintain stable performance across long production runs.
- Inserts indexed directly on the machine: Simplifies setup and reduces downtime by allowing quick tool changes without removing the insert from the holder.
- Coated holders provide abrasion resistance: Extends holder life in demanding production environments, maintaining accuracy and reducing replacement costs.
Designed for Swiss‑type and automatic lathes, this insert supports reliable threading and turning with repeatable results across high‑volume runs. The combination of direct indexing, grounded edges, and abrasion‑resistant holders helps your shop improve throughput, minimize downtime, and consistently hit tight tolerances on threaded and turned parts.
