Seco 00049968 Threading Insert 8 Tpi Un Carbide CP500

Product Description

The SECO 00049968 is a laydown threading insert engineered for external UN thread profiles at 8 threads per inch. Built from solid carbide with a CP500 manufacturer grade, it features a TiAlN/TiN PVD coating applied through physical vapor deposition. The A1 chipbreaker geometry supports consistent chip control during threading operations on cast iron, stainless steel, and carbon steel. The 60-degree included angle matches the UN thread form, and the right-hand cutting orientation suits standard external threading passes on CNC lathes and manual thread-cutting setups. Part of the SECO Snap-Tap series, this insert is designed for repeatability in high-volume threading applications where dimensional accuracy matters.

This insert is intended for external threading on round workpieces using a compatible 16ER-style toolholder. It suits production environments where ISO-standard threading inserts are specified. Primary workpiece materials include cast iron (K), stainless steel (M), and steel (P), making it a practical choice for general machining shops, aerospace component work, and industrial parts production. The PVD TiAlN/TiN coating helps extend tool life in abrasive and work-hardening materials. This product is sold individually with a minimum order quantity of 2 units.
