Kennametal 1113063 NG3078 KC730 Grooving Insert Top Notch

Product Description

The KENNAMETAL 1113063 is a solid carbide grooving insert in the Top Notch series, designed for turning and grooving operations on CNC lathes and turning centers. It carries a KC730 grade designation and a PVD-applied TiN coating that improves wear resistance and extends tool life in demanding cutting applications. The insert features a 1.98 mm cutting width and a maximum depth of cut of 2.39 mm, making it well suited for narrow grooving and parting work. A neutral rake geometry and a 0.19 mm corner radius contribute to stable, consistent chip formation. This insert is installed by machinists and CNC operators working in precision machining environments.

This insert is used in external grooving and parting operations on metalworking lathes and turning centers. It is a right-hand insert configured for the Top Notch toolholding system. Typical applications include grooving on ferrous and non-ferrous metals classified under material grades C2, C3, and C4. The 55-degree included angle and 3-degree lead angle support controlled cutting engagement in production and job-shop turning environments.
