The Carmex Carbide Threading Insert – NPS, TiAlN Coated, 14-14NPS is a versatile, high-precision cutting insert designed to cover the most common thread profiles with reliability and efficiency.

• Five length options: available in a 12 mm to 40 mm range to suit a wide variety of pitches and tool setups.
• TiAlN coating: TiAlN coating provides enhanced wear and heat resistance, helping maintain edge life during challenging threading operations.
• Carbide body: solid carbide construction delivers stiffness and consistent cutting performance for accurate thread formation.
• Double-sided cutting edges: each insert carries two cutting edges for extended life and lower tooling costs (note: BSPT/NPT/NPTF/American Buttress/API RD profiles may differ).
• Internal & external capabilities: for many thread profiles, the same insert can machine both internal and external threads, reducing tool changes (excludes ISO/UN/NPSM/UNJ/Acme).
• Comprehensive thread coverage: designed to address a broad range of common thread profiles in a single insert family.

This insert is ideal for machine shops and production environments that service piping, hydraulics, and mechanical assemblies requiring reliable National Pipe Straight Thread (NPS) and related profiles. The dual edges and TiAlN coating deliver longevity and robust performance across a variety of materials and threading tasks, while the five-length options let you optimize for precision pitches from fine (0.5 mm / 32 TPI) up to coarse (6.0 mm / 4 TPI). Whether you're finishing a critical fit or upfront threading work, this Carmex insert helps you complete more jobs with fewer tool changes and greater consistency.
