The Carmex Carbide Threading Insert for NPSM, TiAlN coated, is a versatile threading solution designed for professional machinists who tackle a wide range of common thread profiles. Built for durability and precision, it supports both turning and threading tasks with a single, robust insert family.

• Thread profiles covered: A comprehensive collection that accommodates all common thread profiles, reducing the need for multiple inserts.
• Five length options: Available in 12 mm, 16 mm, 24 mm, 32 mm, and 40 mm lengths to fit different toolholders and depth-of-cut requirements.
• Pitch range: Depending on length, supports pitches from 0.5 mm (32 TPI) to 6.0 mm (4 TPI) for broad compatibility.
• Double‑sided cutting edges: Each insert offers two cutting edges for extended life (except BSPT/NPT/NPTF/American Buttress/API RD).
• Internal & external threading: For many profiles, the same insert can machine both internal and external threads (except ISO/UN/NPSM/UNJ/Acme).
• TiAlN coating on carbide: TiAlN enhances wear resistance and heat tolerance, supporting high-speed, high-feed threading with less wear.

These design strengths translate into real-world benefits: steadier thread quality across profiles, fewer tool changes, and longer insert life in demanding materials. Ideal for CNC lathes and manual machines alike, this insert family helps shops streamline workflows, maintain consistency on critical NPSM and related threads, and maximize productivity without sacrificing accuracy.
