Carmex 16ER16ACMEBXC Threading Insert 16 Tpi Acme Carbide

Product Description

The CARMEX 16ER16ACMEBXC is a solid carbide laydown threading insert designed for cutting external Acme threads at 16 threads per inch. The insert features a 29-degree included angle, a TiN coating applied via PVD process, and a right-hand cutting orientation. With a 3/8-inch inscribed circle and a thickness of 0.146 inches, it is built to tight dimensional tolerances for repeatable thread form accuracy. This insert is intended for use on CNC lathes and threading machines in professional machining and manufacturing environments. Grade BXC provides a balance of hardness and edge retention suited to a wide range of workpiece materials.

This insert is rated for universal primary workpiece material compatibility, covering material codes H, K, M, N, P, and S. Typical applications include cutting Acme lead screw threads, power transmission components, and linear actuator elements on both ferrous and non-ferrous materials. It is suited for production shops, tool rooms, and maintenance machining operations where Acme thread forms are required on external diameters.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer torque and seating requirements for 16 ER laydown inserts. Power down and lock out the machine before changing inserts. Use the correct torx or clamping wrench specified by the toolholder manufacturer to avoid seat damage. Inspect the insert pocket and clamping components for wear or debris before seating a new insert.
