The Carmex Carbide Threading Insert – NPS, TiAlN coated, 14-18 NPS – is a versatile tool designed for machinists who need reliable threading across a wide range of profiles. Built for shops that value longevity and consistent results, this insert handles many common thread forms with a single, robust solution.

• Five length options: Available in five lengths (12 mm to 40 mm) to match tool reach and bore depth for diverse threading tasks.
• Wide pitch compatibility: Depending on length, supports pitches from 0.5 mm (32 TPI) to 6.0 mm (4 TPI) for broad threading coverage.
• Double‑sided cutting edges: Each insert has two cutting edges to extend tool life (note: BSPT, NPT, NPTF, American Buttress, and API RD are exceptions).
• Internal & external threading: For many thread profiles, the same insert can machine both internal and external threads, reducing tool changes (exceptions: ISO, UN, NPSM, UNJ, Acme).
• TiAlN coating on carbide: TiAlN coating enhances wear resistance and heat tolerance, helping maintain precision and extend insert life in demanding materials.

Whether you’re running quick prototype jobs or steady production, this Carmex threading insert delivers consistent thread quality with fewer tool changes. The combination of multiple lengths, dual cutting edges, and a durable TiAlN coating translates to longer tool life, reliable performance, and streamlined tooling for a wide range of thread profiles.
