Description

The SECO 00075018 is a laydown threading insert designed for external UN thread cutting at 4 threads per inch (TPI). Built from solid carbide with a TiAlN/TiN PVD coating, this insert belongs to the Snap-Tap series and carries the CP500 manufacturer grade. It features a 60-degree included angle and a right-hand cutting orientation, making it suited for standard external UN threading operations on CNC lathes and turning centers. The inscribed circle measures 15.88 mm and the insert thickness is 6.15 mm (0.2421 inches). Installation and indexing are handled by machinists and CNC operators working with compatible Snap-Tap toolholders.

This insert is intended for external threading applications conforming to UN thread standards at 4 TPI. The CP500 grade with PVD TiAlN/TiN coating supports a universal primary workpiece material designation, covering material codes K, M, N, P, and S, which span a broad range of common engineering materials including steel, stainless, cast iron, non-ferrous alloys, and heat-resistant superalloys. It is well suited for production threading on general-purpose turning equipment in both job shop and manufacturing environments.
