Carmex Carbide Threading Insert - NPSM, TiAlN coated, is a durable, versatile tool designed for professional machinists who need reliable threading performance across a wide range of profiles. Built to withstand demanding turning operations, it delivers consistent thread quality and long edge life.

• Length options: Five lengths available from 12 mm to 40 mm, giving you the reach you need for different toolholders and workpiece sizes.
• Pitch range: Supports thread pitches from 0.5 mm (32 TPI) up to 6.0 mm (4 TPI), enabling both fine and coarse thread work with a single insert family.
• Coating and material: TiAlN-coated carbide for enhanced hardness, heat resistance, and extended insert life in demanding threading applications.
• Double-sided cutting edges: Most profiles use two cutting edges to maximize usage; certain profiles (BSPT, NPT, NPTF, American Buttress, API RD) use a single edge.
• Internal/External threading capability: For many profiles, the same insert can machine both internal and external threads, improving setup efficiency; note that ISO, UN, NPSM, UNJ, and Acme profiles require dedicated edge configurations.
• Thread profile coverage: A versatile collection designed to cover all common thread profiles, simplifying tooling and expanding the range of parts you can produce with a single insert type.

In everyday shop use, this Carmex threading insert helps you generate precise threads on fasteners, fittings, and custom components, while reducing tool changes and inventory heft. Its carbide body and TiAlN coating stand up to repetitive cuts and high-temperature environments, providing dependable performance across a broad spectrum of materials.
