Carmex Carbide Threading Insert - NPSM - TiAlN Coated - 40I11.5NPSM

The Carmex Carbide Threading Insert is a TiAlN-coated carbide insert designed to cover all common thread profiles with a single, flexible solution. Built for machinists and workshops that demand reliability and efficiency, it handles a wide range of threading tasks with minimal tool changes.

• TiAlN coating: High hardness and excellent wear resistance at elevated temperatures, helping extend insert life in demanding threading operations.
• Five length options (12 mm to 40 mm): A versatile range that adapts to different workpiece depths and available toolholders, reducing the need for multiple inserts.
• Double-sided cutting edges: Each insert provides two cutting edges for extended life and fewer tool changes (exceptions apply for BSPT/NPT/NPTF/American Buttress/API RD profiles).
• Internal & external threading capability: For many thread profiles, the same insert can machine both internal and external threads, improving workflow and reducing tool inventory (excluding ISO/UN/NPSM/UNJ/Acme).
• NPSM-focused compatibility: Specifically suitable for NPSM threading profiles, supporting common mechanical fits in a single insert family.
• Pitch range and versatility: Depending on length, supports pitches from 0.5 mm (32 TPI) up to 6.0 mm (4 TPI), enabling a broad set of thread types without swapping inserts.

Designed to streamline threading workflows, this insert delivers consistent performance across many profiles while minimizing tool changes. Its robust TiAlN coating and double-edged geometry help you achieve clean, accurate threads with fewer interruptions, making it a practical choice for precision turning and tapping applications.
