Kennametal 1724297 Threading Insert 14 Tpi Un Carbide

Product Description

The KENNAMETAL 1724297 is a solid carbide laydown threading insert designed for right-hand external UN threading operations. Running at 14 threads per inch (TPI), this insert carries the ISO designation LT16ER14UN and is manufactured to KENNAMETAL grade KC5010 with a PVD-applied TiAlN coating. The TiAlN finish provides thermal resistance and wear protection, extending tool life in demanding threading applications. With an inscribed circle of 3/8 inches (9.53 mm) and a thickness of 0.143 inches (3.44 mm), it is built to tight dimensional tolerances for consistent thread form and repeatable performance. Machinists and CNC lathe operators install this insert into compatible LT-style threading toolholders.

This insert is suited for external UN thread cutting on a range of workpiece materials including steel, stainless steel, cast iron, superalloys, and titanium. The KC5010 grade is positioned for tough and interrupted-cut scenarios where coating adhesion and substrate toughness both matter. Typical applications include threading on turned components in industrial, aerospace, and general machining environments. This insert is sold individually with a minimum order quantity of 10 units.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before changing inserts. Use the correct torque wrench and clamping screw specified by the toolholder manufacturer — do not overtighten the clamp screw, as this can fracture the carbide substrate. Verify insert seating and thread form with a test pass before running production.
