Carmex Carbide Threading Insert - NPSM - TiAlN Coated - 40E11.5NPSM

The Carmex Carbide Threading Insert for NPSM, TiAlN coated, model 40E11.5NPSM is a versatile threading solution built for professionals who machine standard pipe and mechanical threads. With TiAlN-coated carbide for durability and a broad range of lengths and pitches, it’s designed to handle many common thread profiles with reliability.

• Thread profile coverage: A versatile collection of threading inserts that covers all common thread profiles.
• Five length options: Available in five lengths ranging from 12 mm to 40 mm to suit different depths and access conditions.
• Pitch range: Supports pitches from 0.5 mm (32 TPI) to 6.0 mm (4 TPI).
• Material & coating: Carbide inserts coated with TiAlN for improved wear resistance and heat tolerance.
• Double-sided cutting edges: Inserts are double-sided with two cutting edges (except for BSPT / NPT / NPTF / American Buttress / API RD).
• Internal/External capability: For many thread profiles, the same insert can machine both internal and external applications (except ISO / UN / NPSM / UNJ / Acme).
• NPSM compatibility: Specifically suitable for NPSM (National Pipe Straight Mechanical) thread forms.

This design delivers practical, real-world benefits: you gain broad coverage across common thread profiles with a single insert family, reducing tool changes and inventory complexity. The TiAlN coating adds wear life and resilience in demanding materials and higher-speed applications, helping you finish more parts per shift. The double-sided edges provide additional reuse opportunities, and the internal/external capability expands where you can use each insert—streamlining workflows on both holes and shafts in plumbing, mechanical assemblies, and other threaded components.
