The Carmex Carbide Threading Insert - NPT, TiAlN coated - 40-11.5NPT is a versatile threading solution designed for professionals who need reliable performance across common thread profiles, including pipe threads.

• TiAlN-coated carbide: TiAlN coating delivers increased hardness and wear resistance, helping the insert maintain sharpness at higher speeds and temperatures.
• Five length options: Available in five lengths that span from 12 mm to 40 mm to accommodate different depths and workpiece geometries.
• Wide pitch range: Suitable for pitches from 0.5 mm (32 TPI) to 6.0 mm (4 TPI), covering the most commonly requested thread profiles.
• Double-sided cutting edges: The insert is designed with two cutting edges for extended life and versatility, with exceptions for BSPT / NPT / NPTF / American Buttress / API RD.
• Internal/External threading versatility: For many thread profiles, the same insert can machine both internal and external threads, reducing tool changes—note exceptions for ISO / UN / NPSM / UNJ / Acme.

This insert combines durable carbide with a protective TiAlN coating to deliver consistent performance across demanding threading tasks. Its broad length options and wide pitch range make it a practical choice for shops that handle a variety of pipe and standard thread profiles, helping you reduce tool inventory while maintaining reliable results.
