The Carmex Carbide Threading Insert - NPT - TiAlN Coated - 30-8NPT is a high-precision, versatile threading solution designed for machinists who need reliable performance across multiple profiles with minimal tool changes.

• Profile coverage: A versatile collection that covers all common thread profiles, reducing the need for multiple inserts.
• Length options: Five lengths available, ranging from 12 mm to 40 mm, to fit different tooling setups and depth requirements.
• Pitch range: Accepts pitches from 0.5 mm (32 TPI) up to 6.0 mm (4 TPI), enabling a broad range of applications with a single insert family.
• Double-sided cutting edges: Each insert provides two cutting edges for extended life (except for BSPT/NPT/NPTF/American Buttress/API RD profiles).
• Internal & external capability: For many thread profiles, the same insert can machine both internal and external threads (with exceptions for ISO/UN/NPSM/UNJ/Acme).
• Material & coating: Carbide insert with TiAlN coating, offering improved wear resistance and heat management for longer tool life.
• Code and compatibility: Specifically designed as NPT-thread insert (30-8NPT) to support reliable progression through common NPT threading tasks.

This insert translates into tangible productivity gains: tougher TiAlN coating lives longer under high-speed, high-heat threading; dual edges and the broad profile coverage reduce tool changes and setup time; and the internal/external compatibility simplifies job planning. It’s particularly well-suited for shops handling a mix of threading tasks where precision, consistency, and tool longevity matter most. By choosing the 30-8NPT variant, you’re selecting a robust solution that supports varied NPT threading needs with fewer inserts in your kit.
