The Carmex Thread Turning Internal Insert is a precision carbide insert designed for internal threading on metal workpieces. Its laydown triangular geometry is engineered for steady, reliable cutting in a variety of lathes and CNC machines, delivering consistent thread profiles with minimal setup adjustment.

Its versatile design makes it well-suited for both straightforward and more demanding threading applications.
- Broad Thread Standard Compatibility: Covers BSW, BSF, BSP, and BSB threads, enabling diverse internal threading tasks with one insert and reducing tool-change downtime.
- Durable Triangular Laydown Geometry: Laydown triangular design provides rigidity and efficient chip control for longer tool life and cleaner thread finishes.
