Carmex Internal Right Hand Trapezoidal (TR) Thread Turning Insert 16 mm / 3.0 mm Pitch / 16 IR 3.0 TR BMA

Internal Thread Turning Insert – Trapezoidal 30° (TR) Profile

The Carmex 16 IR 3.0 TR BMA is a precision-engineered internal thread turning insert designed for cutting Trapezoidal (TR) 30° thread profiles with a 3.0 mm pitch. It produces the complete thread form—crest, root, and flank angles—in a single pass, ensuring high dimensional accuracy, excellent surface finish, and superior thread strength for lead screw and power transmission applications.

Manufactured from premium BMA-grade carbide, the insert provides exceptional wear resistance, toughness, and thermal stability. It is ideal for threading stainless steels, hardened alloys, and other difficult-to-machine materials, offering smooth chip flow, stable performance, and long service life in high-precision internal threading operations.
