Kennametal 1712610 Threading Insert 28 Tpi KC5025 Carbide

Product Description

The KENNAMETAL 1712610 is a laydown threading insert designed for external UN thread cutting on CNC lathes and turning centers. Manufactured from solid carbide with a PVD-applied TiAlN coating, this ER-style insert carries the ISO designation LT16ER28UNCB and is built to grade KC5025. It cuts right-hand external threads at 28 threads per inch (TPI) with a 3/8-inch inscribed circle and a thickness of 0.1430 inches (3.44 mm). The TiAlN finish provides thermal resistance and extended tool life in demanding cutting environments. This insert is sold individually with a minimum order quantity of 10.

This insert is suited for threading operations on steel, stainless steel, cast iron, superalloys, and titanium. It is a right-hand insert intended for external UN-standard thread profiles at 28 TPI, making it applicable across a range of threaded fastener and component machining jobs in precision manufacturing, job shops, and production turning environments. A machinist or CNC operator installs this insert into a compatible ER-style laydown threading toolholder.
