The Carmex Polygon Swiss Line Insert for threading (Partial 55°), Right Hand, GT25RA55BLU, is a precision indexable tool designed for Swiss-type lathes and automatic lathes. It enables high‑volume threading and supports a range of turning operations—external grooving, back/front turning, profiling, thread turning, parting, and general turning—delivering reliable performance in demanding production environments.

With grounded cutting edges and a geometry optimized for Swiss machines, this insert can be indexed directly on the tool holder, simplifying setup and reducing downtime. The coated holders add abrasion resistance to stand up to tough threading tasks and help maintain consistent results over long production runs.

• Grounded cutting edges: Deliver precise, repeatable cuts and extended edge life for cleaner threads and smoother finishes.
• In‑machine indexable inserts: Enable fast tool changes and direct indexing on the machine, minimizing setup time and maximizing uptime.
• Coated holders for abrasion resistance: Protect against wear in demanding turning and threading applications, helping maintain accuracy and extend tool life.

Designed for high‑volume production, this insert provides reliable, consistent threading performance with easy setup and strong wear resistance, helping you finish parts faster and with tighter control over quality and surface finish.
