Seco 00045894 Threading Insert 16 Tpi 1/4 in Ic Un

Product Description

The SECO 00045894 is a solid carbide laydown threading insert designed for internal UN thread cutting at 16 threads per inch. Part of the Snap-Tap series, it features a TiAlN/TiN PVD coating applied over a carbide substrate rated to the CP500 manufacturer grade. The insert follows the 11NR style profile with a 60-degree included angle, a 1/4-inch inscribed circle, and a thickness of 0.1181 inches. It is intended for right-hand internal threading operations on CNC lathes and turning centers. Licensed machinists and CNC operators are the primary installers of this tooling component.

This insert is suited for a wide range of workpiece materials, including ferrous metals, non-ferrous alloys, stainless steels, heat-resistant superalloys, and cast materials, as indicated by universal primary workpiece material codes K, M, N, P, and S. It is a strong fit for job shops, production turning environments, and maintenance machining operations where standard UN internal threads must be cut consistently and accurately. The ISO-standard geometry ensures compatibility with holders designed for 11NR-style inserts.

Installation Notes

This insert is installed by a qualified CNC machinist or toolroom technician. Power down and lock out the machine before changing inserts. Use the correct torque wrench and insert screw for the specific toolholder to secure the insert without cracking the carbide. Verify thread pitch and hand orientation against the job drawing before beginning a threading pass.
