Carmex External Right Hand BSPT Thread Turning Insert 11 TPI / 16 ER 11 BSPT BMA

External Thread Turning Insert – BSPT Full Profile 55°

The BSPT Full Profile External Thread Turning Insert is designed for cutting British Standard Pipe Taper (BSPT) threads with precision and consistency. With a 55° thread angle and a pitch of 11 TPI, this insert forms the complete BSPT thread profile—including crest, root, and flanks—in one pass, ensuring pressure-tight sealing for pipe fittings and hydraulic components.

Manufactured from high-performance BMA-grade carbide, the insert provides excellent wear resistance and edge strength, even in demanding materials like stainless steels and high-tensile alloys. Its optimized X and Y geometry delivers smooth engagement, consistent cutting performance, and efficient chip evacuation during external threading operations.
