Kennametal 1113899 Grooving Insert NG3062 KC850 Carbide

Product Description

The KENNAMETAL 1113899 is a solid carbide grooving insert designed for precision external and internal grooving operations on CNC lathes and turning centers. Part of the Top Notch series, it carries a CVD-applied TiC, TiCN, and TiN multilayer coating in the KC850 grade, delivering wear resistance and thermal stability across a range of workpiece materials. The insert features a 1.58 mm cutting width and a maximum depth of cut of 2.39 mm, with a neutral rake geometry and a 0.19 mm corner radius. It is a left-hand configuration intended for specific toolholder orientations. Machinists and tooling technicians working with C5 and C6 material grades will find this insert suited to finish and semi-finish grooving passes.

This insert is applied in production turning environments where consistent groove geometry and tool life are critical. Typical applications include grooving, parting, and profiling on ferrous and non-ferrous materials in both job-shop and high-volume manufacturing settings. The NG insert style fits Top Notch series toolholders designed for NG-profile inserts. It is a single-use, non-multi-use insert sold individually with a minimum order quantity of 5 units.
