Carmex Carbide Threading Insert - NPSF - TiAlN Coated - 14-14NPSF is a versatile collection of carbide inserts designed to cover the most common thread profiles in a single, durable tool. Built for machine shops and precision manufacturers, it delivers reliable performance across a range of threading tasks with a focus on efficiency and consistency.

• TiAlN coating: TiAlN-coated carbide inserts resist wear and heat, extending tool life and maintaining sharpness at higher speeds.
• Five length options: A set available in five lengths, from 12 mm to 40 mm, to suit different thread pitches and approach depths.
• Double‑sided cutting edges: Each insert provides two cutting edges for more usable life and cost efficiency (note: BSPT/NPT/NPTF/American Buttress/API RD may differ).
• Internal and external threading compatibility: In many profiles, the same insert can machine both internal and external threads, reducing changeovers (exception: ISO/UN/NPSM/UNJ/Acme).
• Wide pitch range: Supports pitches from 0.5 mm (32 TPI) up to 6.0 mm (4 TPI), covering the majority of standard thread forms.

This Carmex insert family is ideal for workshops that need flexible, reliable threading capabilities without maintaining a large library of different inserts. The combination of TiAlN coating, dual cutting edges, and broad pitch compatibility helps you achieve consistent thread quality on a variety of materials—stainless steel, alloy, and machining-grade steels included—while keeping tooling costs in check.
