Carmex Carbide Threading Insert - NPT - TiAlN Coated - 30-11.5NPT

Meet the Carmex Carbide Threading Insert for NPT — a versatile, TiAlN-coated threading solution built for machinists who need reliable performance across common thread profiles. Ideal for internal and external threading tasks, it minimizes tool changes while delivering consistent, precise results.

• TiAlN coating: TiAlN-coated carbide construction enhances hardness and wear resistance for longer insert life in demanding threading jobs.
• Broad thread-profile coverage: A versatile collection that spans all the common thread profiles you encounter in typical manufacturing and maintenance work.
• Five length options: Available in five lengths, ranging from 12 mm up to 40 mm, to fit a variety of tooling setups.
• Wide pitch range: Depending on length, handles pitches from 0.5 mm (32 TPI) to 6.0 mm (4 TPI), giving you flexibility across applications.
• Double-sided cutting edges: Each insert provides two cutting edges for extended use (note: BSPT/NPT/NPTF/American Buttress/API RD profiles are exceptions).
• Internal & external threading versatility: For many profiles, the same insert can machine both internal and external threads, reducing tool changes (exceptions apply for ISO/UN/NPSM/UNJ/Acme).

This threading insert is designed to boost productivity by combining broad compatibility with durable, long-lasting performance. Its wear-resistant TiAlN coating helps maintain accurate thread forms over repetitive cycles, while the double-edged design and multiple lengths let you tailor tooling to your specific job—whether you’re producing pipe fittings, hydraulic components, or precision mechanical assemblies. If you value fewer tool changes, consistent thread quality, and a single solution that covers multiple profiles, this Carmex insert is a practical, reliable choice for shop floors and job shops alike.
