Kennametal 1114366 Threading Insert 12 Tpi KC730 Carbide

Product Description

The KENNAMETAL 1114366 is a carbide threading insert in the Top Notch series, designed for external thread cutting on precision machining applications. It carries the NJP3014R12 insert style designation and is manufactured from carbide with a Titanium Nitride (TiN) finish applied via PVD coating. The insert cuts at 12 TPI with a 60-degree included angle and a right-hand orientation. At 0.1949 inches thick and a corner radius of 0.0130 inches, it is built to hold tight tolerances on UNJ thread forms. Machinists and CNC operators working in aerospace, defense, and high-precision manufacturing environments are the primary users of this insert.

This insert is suited for external threading operations on UNJ thread forms, which are commonly specified in aerospace and military fastener standards. The KC730 grade is a PVD-coated carbide grade rated for material grades C2, C3, and C4, making it appropriate for use on a range of ferrous and non-ferrous workpiece materials. It fits Top Notch series toolholders designed for the NJP insert style and 3014 insert size. This insert is sold individually but carries a minimum order quantity of 5 units.
