Carmex 22UER4ABUTMXC Threading Insert 4 Tpi Solid Carbide

Product Description

The CARMEX 22UER4ABUTMXC is a solid carbide laydown threading insert designed for external American Buttress thread cutting at 4 threads per inch (TPI). The insert carries an MXC grade designation and features a TiN (titanium nitride) coating applied via PVD process, providing enhanced surface hardness and wear resistance during threading operations. With a 1/2 inch inscribed circle and a thickness of 0.187 inches, this right-hand insert fits standard 22ER-style toolholders. It is intended for machinists and CNC operators working in precision threading applications across a broad range of workpiece materials.

This insert is suited for external buttress thread profiles with a 45-degree included angle, commonly encountered in high-load or directional-force applications such as hydraulic cylinders, jacks, and heavy mechanical assemblies. The MXC grade and universal primary workpiece material rating make it compatible with a wide range of materials including steel, stainless steel, cast iron, non-ferrous metals, high-temperature alloys, and hardened materials. Packaged individually, this insert is sold with a minimum order quantity of 10 pieces.

Installation Notes

Installation should be performed by a qualified machinist or CNC technician. Power down and lock out the machine before seating or replacing the insert. Ensure the toolholder pocket and clamping screw are clean and free of debris before installing. Verify insert orientation and confirm right-hand cutting direction matches the programmed tool path before resuming operation.
