Seco 00046056 Threading Insert 24 Tpi Un Carbide

Product Description

The SECO 00046056 is a laydown threading insert engineered for right-hand internal UN thread cutting at 24 threads per inch. Built from solid carbide in the CP500 grade, the insert features a PVD-applied TiAlN/TiN coating for wear resistance across a broad range of workpiece materials. The 60-degree included angle matches the unified thread form. At 0.1181 inches thick with a 1/4-inch inscribed circle, this insert fits standard laydown toolholders designed for the 11NR style. It is sold in a minimum order quantity of two, with individual package quantity of one. Licensed machinists and CNC lathe operators install this insert in threading toolholders for production and maintenance threading operations.

The 00046056 is suited for internal threading on lathes and turning centers in both production shop and job-shop environments. The CP500 carbide grade with PVD coating covers universal workpiece material categories, including cast iron, stainless steel, non-ferrous alloys, carbon and alloy steels, and heat-resistant superalloys, identified under ISO material codes K, M, N, P, and S. The Snap-Tap series design supports consistent insert seating in compatible toolholders. This insert handles applications where a 24 TPI UN thread form is required in through-holes or blind bores of appropriate diameter for a 1/4-inch inscribed circle insert.

Installation Notes

Installation is performed by qualified machinists or CNC lathe operators. Power down and lock out the machine spindle before changing inserts. Seat the insert fully in the toolholder pocket and torque the clamping screw to the toolholder manufacturer specification. Inspect the insert seating and clamping before resuming cutting operations, and verify thread pitch with a calibrated thread gauge after the first pass.
