Kennametal 1114292 Grooving Insert KC730 Solid Carbide

Product Description

The KENNAMETAL 1114292 is a solid carbide grooving insert designed for precision external grooving and turning operations on CNC lathes and machining centers. Part of the Top Notch series, it carries the KC730 manufacturer grade and features a PVD-applied TiN coating for improved wear resistance and edge integrity. The insert delivers a cutting width of 2.39 mm (0.0941 inches) and a maximum depth of cut of 2.79 mm (0.1098 inches), making it well suited for shallow-to-medium groove profiles. The positive rake angle of 10 degrees reduces cutting forces and supports clean chip evacuation in a range of workpiece materials.

This insert is intended for right-hand grooving operations in production and job-shop environments. It fits toolholders in the Top Notch insert system and is appropriate for machining steel, cast iron, and non-ferrous alloys that fall within material grades C2, C3, and C4. The K-style chip breaker promotes controlled chip flow in interrupted and continuous cuts. Machinists working with tight tolerance groove requirements will find the 0.19 mm (0.0075 inch) corner radius and 55-degree included angle suitable for detailed groove geometry.
