Carmex 16ER14UNMXC Threading Insert 14 Tpi 3/8 in Carbide

Product Description

The CARMEX 16ER14UNMXC is a solid carbide laydown threading insert designed for external UN thread cutting at 14 threads per inch. Built from micrograin solid carbide with a PVD-applied TiN coating, it delivers consistent thread geometry and extended tool life in demanding production environments. The 60-degree included angle suits standard UN thread profiles. With a 3/8 inch inscribed circle and 0.146 inch thickness, this is a 16 ER-style insert sized for compatible laydown toolholders. CNC machinists and toolroom operators use this insert on lathes for right-hand external threading passes on a wide range of workpiece materials.

This insert is rated for universal primary workpiece material compatibility, covering material grade codes H, K, M, N, P, and S. That range covers carbon steels, alloy steels, stainless, cast iron, non-ferrous metals, and heat-resistant superalloys. It suits both high-production CNC turning centers and manual lathes where precise UN thread form accuracy is required. The MXC grade designation indicates a micrograin carbide substrate engineered for fine thread work and interrupted-cut resistance. This product is sold individually; minimum order quantity is 10 units.

Compatibility

Designed for use in 16 ER-style laydown threading toolholders. Compatible with workpiece materials graded H, K, M, N, P, and S per ISO material classification, covering a broad range of steels, cast irons, non-ferrous metals, and heat-resistant alloys.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the lathe spindle is fully stopped and the machine is in a safe state before indexing or replacing inserts. Seat the insert fully into the toolholder pocket and torque the clamping screw to the toolholder manufacturer specification. Verify insert orientation and thread hand before beginning a threading pass.
