Kennametal 1114262 NRD3062 KC730 Grooving Insert Carbide

Product Description

The KENNAMETAL 1114262 is a solid carbide grooving insert from the Top Notch series, designed for external grooving and parting operations on CNC lathes and turning centers. It carries a PVD-applied TiN coating and is configured for right-hand cutting with a neutral rake geometry. The insert measures 0.125 inches (3.18 mm) in cutting width and supports a maximum depth of cut of 0.250 inches (6.35 mm). KC730 is a KENNAMETAL carbide grade suited for a wide range of turning applications, offering a balance of toughness and wear resistance. Licensed machinists and CNC operators install this insert in compatible Top Notch toolholders.

This insert is used in precision grooving applications where consistent width control and surface finish are critical. It is appropriate for use on ferrous materials across material grades C2, C3, and C4. The full-radius geometry with a corner radius of 0.0626 inches (1.59 mm) makes it well suited for groove-bottom contouring and controlled chip formation. Typical applications include external grooving on bar stock and turned components in job shop and production environments.
