Carmex Swiss Line Insert - Threading (55°) - Left Hand, GT19LA55BLU, is a purpose-built indexable cutting tool designed for Swiss-type machines and automatic lathes. Ideal for high‑volume production, it enables cost‑efficient external grooving, back/front turning, profiling, thread turning, parting, and general turning tasks with reliable performance. The 55° threading angle and left‑hand design are optimized for precise, consistent thread production on a range of materials.

• Grounded cutting edges: Delivers consistent edge quality and smooth surface finishes, reducing finishing passes and helping parts meet tight tolerances.
• Direct machine indexing: Allows quick edge indexation right on the machine, minimizing tool changes and maximizing uptime in high‑volume Swiss turning operations.
• Coated holders for abrasion resistance: Extends tool life in tough materials and abrasive workpieces, enhancing reliability and reducing replacement costs.

Designed for engineers, machinists, and production buyers, this insert delivers predictable performance and durable longevity in demanding threading and turning applications. It helps streamline setup, reduce downtime, and maintain consistent thread quality across batches, so you can meet production targets with confidence.
