Carmex External Right Hand NPT Thread Turning Insert 14 TPI / 16 ER 14 NPT BMA

External Thread Turning Insert – NPT Full Profile

The NPT Full Profile External Thread Turning Insert is designed for precise threading of National Pipe Taper (NPT) threads. With a pitch of 12 TPI and a 60° thread angle, this insert forms the complete thread profile—crest, root, and flanks—ensuring pressure-tight and dimensionally accurate pipe threads suitable for fluid and gas systems.

Crafted from BMA-grade carbide, this insert offers superior wear resistance, thermal stability, and edge retention, making it ideal for machining stainless steel, alloys, and other tough materials. Optimized X and Y dimensions provide smooth cutting action, chip control, and consistent performance in high-volume threading applications.
