Carmex Carmex External Right Hand ACME Thread Turning Insert 16 mm / 6 TPI / 16 ER 6 ACME P25C

External Thread Turning Insert – ACME 29o Full Profile

The Carmex 16 ER 6 ACME P25C is a high-precision external thread turning insert engineered for producing ACME (29o) trapezoidal threads with a 6 TPI pitch. It generates the full thread form-including crest, root, and flanks-in a single pass, ensuring superior dimensional accuracy, thread strength, and surface finish for power transmission and lead screw applications.

Constructed from premium P25C-grade carbide, the insert provides excellent wear resistance, toughness, and heat stability. It performs optimally on steels and alloy steels under medium-speed cutting conditions, offering smooth chip control, stable cutting performance, and extended tool life in both general-purpose and production threading operations.
