Kennametal 1114372 Threading Insert 16 Tpi KC730 Carbide

Product Description

The KENNAMETAL 1114372 is a carbide threading insert designed for external thread cutting on CNC lathes and turning centers. Carrying the KC730 manufacturer grade with a PVD-applied Titanium Nitride (TiN) finish, this insert delivers wear resistance and edge stability during single-point threading operations. It produces right-hand UNJ-standard external threads at 16 TPI with a 60-degree included angle. The corner radius measures 0.0099 inches (0.25 mm), and the insert thickness is 0.1949 inches (4.95 mm). Tip-to-top height is 0.1409 inches (3.58 mm). It fits the Top Notch insert system and is installed by machinists and CNC operators working in precision threading applications.

This insert is suited for threading operations in aerospace, defense, and general machining environments where UNJ thread forms are specified. The NJK insert style in size 3010 seats into compatible Top Notch toolholders. Material grades C2, C3, and C4 indicate suitability across a range of workpiece materials including carbon steels, alloy steels, and cast irons. Minimum order quantity is 5 pieces; each package contains 1 insert.
