Carmex Carbide Threading Insert - NPSF - TiAlN Coated - 40-11.5NPSF

Carmex Carbide Threading Insert - NPSF, TiAlN coated is a versatile, high-precision threading solution designed for machinists and job shops that need reliable performance across a wide range of profiles.

• Coating: TiAlN-coated carbide for improved wear resistance and longer edge life in demanding threading tasks.
• Material: Solid carbide substrate provides rigidity and consistent cutting action for precise threads.
• Cutting Edges: Double-sided design with two cutting edges to maximize use before reindexing (except for BSPT/NPT/NPTF/American Buttress/API RD profiles).
• Profile Coverage: Covers all common thread profiles, enabling efficient tooling across multiple projects with a single insert family.
• Length Options: Five lengths ranging from 12 mm to 40 mm to match tool holders and workpiece geometry.
• Pitch Range: Depending on length, handles pitches from 0.5 mm (32 TPI) up to 6.0 mm (4 TPI) for versatile threading capability.
• Internal/External Capability: For many thread profiles, the same insert can machine both internal and external threads, reducing tool changes (note: some profiles like ISO/UN/NPSM/UNJ/Acme have dedicated considerations).
• Designation: NPSF threading insert optimized for National Pipe Straight Fin applications within the Carmex line.

This insert is an excellent choice for workshops and production environments that want to streamline threading operations without swapping tools for every profile. The TiAlN coating helps maintain sharpness on hard materials, while the dual-edge design and multiple length options offer flexibility to achieve clean, accurate threads with fewer interruptions. Ideal for piping, fastener, and hydraulic components where consistent thread quality and tool longevity matter.
