Kennametal 2599757 Grooving Insert NR2031 KC5010 Carbide

Product Description

The KENNAMETAL 2599757 is a solid carbide grooving insert in the Top Notch series, designed for external grooving and parting operations on CNC lathes and turning centers. It carries a KC5010 grade designation with a PVD-applied TiAlN coating, which provides wear resistance and thermal stability during interrupted and continuous cuts. The insert is right-hand orientation with a 1.58 mm cutting width, a maximum depth of cut of 2.79 mm, and a full-radius corner profile with a 0.79 mm corner radius. Machinists and toolroom operators install this insert into compatible Top Notch toolholders for precision groove turning on steel, stainless, and cast iron workpieces.

This insert is suited for production turning environments where consistent groove geometry and surface finish are required. The neutral rake geometry and 55-degree included angle make it appropriate for both light and moderate grooving passes. It is sized as an NR 2031 insert and is sold individually, with a minimum order quantity of 5 units. Applications include groove turning, undercut machining, and snap-ring groove production on turned components in general manufacturing and job shop settings.
