Product Description

The SECO 00045933 is a laydown threading insert designed for right-hand internal UN thread cutting operations. Manufactured from solid carbide in the CP500 grade with a PVD-applied TiAlN/TiN coating, this insert delivers consistent thread form geometry on a wide range of workpiece materials. It produces 60-degree included angle UN threads at 18 threads per inch (TPI), with a 1/4-inch inscribed circle and a thickness of 0.1181 inches. The 11NR insert style seats flat in compatible Snap-Tap toolholders. This insert is specified by machinists, tool-and-die technicians, and CNC lathe operators working to UN thread standards.

This insert is suited for internal threading on lathes and turning centers handling universal workpiece material classifications including cast iron, stainless steel, non-ferrous metals, carbon steel, and heat-resistant superalloys (ISO material codes K, M, N, P, and S). The CP500 grade with PVD coating is well suited to both light production and general-purpose threading where consistent flank wear resistance is required. The 11NR designation identifies the insert style for direct toolholder selection in Snap-Tap series boring bar and threading holders.

Compatibility

Designed for use in Snap-Tap series toolholders accepting the 11NR laydown insert style. Compatible with lathes and CNC turning centers set up for right-hand internal UN threading operations. Verify toolholder pocket geometry and insert seating requirements before installation.

Installation Notes

Installation is performed by qualified machinists or CNC lathe operators. Power down and lock out the spindle before changing inserts. Use the correct torque wrench and clamping screw specified by the toolholder manufacturer do not overtighten, as carbide inserts are brittle and can fracture under excess clamping force. Inspect the toolholder pocket for wear or debris before seating the insert, and confirm thread pitch and hand orientation against the job drawing before beginning the cut.
