• Indexed inserts for on‑machine setup: Inserts can be indexed directly on the machine for fast, downtime-saving changes, keeping production moving without removing the tool from the holder.
• Grounded cutting edges for consistent results: Precision-ground edges deliver stable, accurate cuts and smooth finishes, reducing chatter and improving part quality across long runs.
• Coated holders for abrasion resistance: The coated holders resist wear, extending tool life in demanding turning applications and helping lower replacement and maintenance costs.

Designed to integrate smoothly into Swiss-type workflows, this left-hand configuration delivers reliable performance across parting off, grooving, and various turning operations. The combination of indexable inserts, grounded edges, and abrasion-resistant holders helps you reduce setup time, minimize tool changes, and achieve repeatable results in high‑volume production environments.
