The Carmex Swiss Line Insert for Threading (60°) – Left Hand, GT19LA60BLU, is a purpose-built threading tool designed for Swiss-type lathes and automatic turning centers. It delivers precise external 60° threads with consistent quality, making it ideal for high-volume production and parts with tight tolerances.

Engineered for durability in demanding shop floors, this insert is designed to index directly on the machine, so you can rotate to a fresh edge without removing the holder. Grounded cutting edges and abrasion-resistant coatings on the holder help maintain reliable performance across long production runs.

• Grounded cutting edges: Delivers crisp, accurate thread profiles with reduced vibration and longer edge life, maintaining quality across high-speed Swiss turning.
• Inserts can be indexed directly on the machine: Enables quick edge changes without disassembly, reducing downtime and boosting productivity on repetitive threading jobs.
• Coated holders provide abrasion resistance: Extends tool life in tough turning conditions, resisting wear and helping sustain consistent surface finish and thread accuracy.

By pairing a dedicated 60° left-hand threading geometry with machine-indexable inserts and durable coatings, this Carmex tool supports efficient, reliable Swiss-type threading workflows. Expect repeatable thread quality, faster changeovers, and longer tool life, all contributing to improved throughput and lower part costs over time.
