Carmex Carbide Threading Insert - NPS - TiAlN Coated - 12-18NPS

Meet the Carmex Carbide Threading Inserts for NPS—TiAlN-coated carbide tooling built to cover the most common thread profiles with reliability and ease. Ideal for professional machinists and job shops, this versatile set helps you complete threading tasks with fewer tool changes and consistent results.

• TiAlN coating: TiAlN coating enhances wear resistance and heat tolerance, helping inserts stay sharp longer during high-speed threading.
• Comprehensive thread profiles coverage: A versatile collection designed to handle all common thread profiles, reducing the need to switch between different inserts.
• Five length options: Five lengths available (from 12 mm to 40 mm) to fit a range of threading depths and applications.
• Double-edged design: Inserts are double-sided with two cutting edges (except for BSPT/NPT/NPTF/American Buttress/API RD profiles), maximizing usage and extending life between changes.
• Internal and external threading capability: For many thread profiles, the same insert can machine both internal and external threads, streamlining setup and inventory (note: ISO/UN/NPSM/UNJ/Acme profiles may require alternate geometries).

This Carmex threading insert set is an efficient, durable choice for workshops that handle a mix of metric and imperial threads. With broad profile compatibility, multiple length options, and a robust carbide substrate, it supports precise thread formation, smooth finishes, and longer tooling life—even on demanding materials and higher-speed operations.
