Carmex 16ER16UNMXC/G Threading Insert 16 Tpi 3/8 in Ic

Product Description

The CARMEX 16ER16UNMXC/G is a solid carbide laydown threading insert engineered for right-hand external UN thread cutting at 16 threads per inch (TPI). The insert features a 60-degree included angle and a 3/8-inch inscribed circle (IC), making it a standard geometry for UN thread profiling on CNC lathes and threading equipment. A physical vapor deposition (PVD)-applied TiN coating increases surface hardness and extends tool life across a wide range of workpiece materials. The MXC grade designation reflects CARMEX's multi-purpose carbide substrate, suitable for demanding threading applications in production environments.

This insert is intended for external UN threading operations in both job-shop and production-floor settings. It fits standard ER-style laydown threading toolholders sized for 16-series inserts. The universal primary workpiece material classification means it performs across carbon steels, stainless steels, cast iron, non-ferrous alloys, and high-temperature alloys, making it a practical single-grade choice for shops threading a variety of materials without frequent insert changeovers.

Compatibility

Designed as a replacement or production-run insert for ER-style laydown threading toolholders accepting 16-series inserts configured for external UN threading.

Installation Notes

Threading inserts are seated and clamped by qualified machinists or CNC tooling setters following machine tool manufacturer guidelines. Ensure the toolholder pocket and clamping screw are clean and free of debris before seating the insert. Power down and lock out the machine before any insert change. Do not exceed the toolholder manufacturer's recommended depth-of-cut or feed parameters for this insert geometry.
