The Carmex Carbide Threading Insert, Unified, TiAlN Coated, model 30I12UN, is a versatile carbide cutting insert designed to tackle a wide range of unified thread profiles with reliability and precision. Built for professional workshops, it delivers consistent results across internal and external threads with minimal setup changes.

• Thread profiles covered: A versatile collection that spans all common unified thread profiles for streamlined machining.
• Length options: Available in five lengths from 12 mm to 40 mm to fit different toolholders and reach depths.
• Pitch range: Compatible with pitches from 0.5 mm (32 TPI) to 6.0 mm (4 TPI), depending on the chosen length.
• Double-sided inserts: Each insert features two cutting edges for extended life (except BSPT/NPT/NPTF/American Buttress/API RD profiles).
• Internal & external capability: In many thread profiles, the same insert can machine both internal and external threads, reducing tool changes (note exceptions for ISO/UN/NPSM/UNJ/Acme).
• Coating: TiAlN coating enhances wear resistance and heat tolerance for longer insert life in demanding materials.
• Material: Carbide substrate provides rigidity and precise thread form for consistent results.

Designed to maximize uptime and thread accuracy, this unified-thread carbide insert helps machinists achieve clean, repeatable threads with fewer inserts and fewer tools to manage. Its two-edge design and TiAlN coating reduce downtime, while the range of lengths and compatibility with multiple pitch options support a broad set of turning and threading applications. Ideal for precision threading in metalworking, screw-machining, and connector fabrication where reliable performance across common thread standards is essential.
