Kennametal 1113562 Grooving Insert NG2031 K68 Solid Carbide

Product Description

The KENNAMETAL 1113562 is a solid carbide grooving insert engineered for precision external and internal grooving operations on CNC lathes and turning centers. Part of the Top Notch series, it carries a K68 manufacturer grade with a bright, uncoated finish suited for cutting non-ferrous metals, cast iron, and hardened materials where coating adhesion may be undesirable. The insert delivers a cutting width of 0.79 mm (0.0311 inches) and a maximum depth of cut of 1.27 mm (0.0500 inches), making it appropriate for fine, narrow-groove applications requiring tight dimensional control. A neutral rake geometry and 3-degree lead angle support stable chip formation during light to moderate grooving passes.

This insert is intended for use on production turning equipment in both job-shop and manufacturing environments. It is configured for right-hand cutting and fits Top Notch series toolholders accepting NG2031 insert geometry. Machinists and CNC operators working in aerospace, automotive, and precision parts production will find this insert well-suited to grooving soft to medium-hard workpiece materials. The 55-degree included angle and 0.09 mm corner radius (0.0035 inches) support controlled chip geometry in confined groove profiles.
