Carmex Internal Right Hand NPT Taper Pipe Thread Turning Insert 16 mm / 8 TPI / 16 IR 8 NPT BMA

Internal Thread Turning Insert – NPT Taper Pipe 60°

The Carmex 16 IR 8 NPT BMA is a precision internal thread turning insert engineered for machining National Pipe Taper (NPT) 60° thread profiles with an 8 TPI pitch. It produces the complete tapered thread geometry—including crest, root, and flanks—in one operation, ensuring accurate thread form, leak-tight sealing, and reliable performance in fluid and gas connection systems.

Manufactured from premium BMA-grade carbide, the insert delivers exceptional wear resistance, edge strength, and thermal stability. It performs superbly on stainless steels, hardened alloys, and other difficult-to-machine materials, providing smooth chip flow, stable cutting action, and long tool life in precision internal threading applications.
