Description
The SECO 00049554 is a solid carbide laydown threading insert designed for external ISO thread cutting at a 1.0 mm pitch. Manufactured to the CP500 grade, it features a TiAlN/TiN PVD coating that improves wear resistance and extends tool life across a wide range of workpiece materials. The insert follows the 16ER style geometry with a 60-degree included angle and a 3/8 inch inscribed circle. It is installed in compatible laydown threading toolholders and is used by machinists and turning specialists performing external ISO threading operations on CNC and manual lathes.
This insert is suited for universal workpiece materials, covering cast iron, steel, non-ferrous metals, heat-resistant alloys, and stainless steel, corresponding to material codes K, M, N, P, and S. It fits into the Snap-Tap series toolholder system and is configured for right-hand cutting. Typical applications include production threading, repair threading, and general-purpose external ISO thread generation in job shop and manufacturing environments.
