The Carmex Carbide Threading Insert for NPS threads is a versatile, TiAlN-coated solution built for machinists who need reliable, multi-profile threading in a single insert. Designed to handle a range of common thread forms, it delivers consistent results across everyday production work.
- Coating: TiAlN coating provides enhanced hardness and wear resistance for longer tool life and better heat tolerance.
- Thread profiles: A comprehensive collection that covers all common thread profiles in a single insert.
- Lengths: Available in 5 lengths, from 12 mm to 40 mm, to suit different tooling setups and applications.
- Cutting edges: Double-sided design with two cutting edges per insert, increasing cutting life (note: BSPT / NPT / NPTF / American Buttress / API RD are exceptions).
- Internal/External capability: For many profiles, the same insert can machine both internal and external threads (with exceptions: ISO / UN / NPSM / UNJ / Acme).
- Pitch range: Depending on length, supports pitches from 0.5 mm (32 TPI) to 6.0 mm (4 TPI), enabling a broad range of threading tasks.
This insert is ideal for production environments, job shops, and maintenance teams that require flexible threading capabilities without maintaining a large assortment of inserts. The TiAlN coating helps resist wear on challenging materials, while the double-edged geometry reduces downtime by extending usable life between indexings. Use it for standard NPS threads in pipes, fittings, fasteners, and mechanical assemblies where reliable, consistent threading is essential.
