Kennametal 1804638 Grooving Insert NG2062 KC5010 Solid Carbide

Product Description

The KENNAMETAL 1804638 is a solid carbide grooving insert in the Top Notch series, designed for external grooving and turning operations on CNC lathes and turning centers. It carries a TiAlN coating applied via PVD process, which increases surface hardness and heat resistance at the cutting edge. The insert is left-hand oriented with a 1.58 mm cutting width, a maximum depth of cut of 2.79 mm, and a corner radius of 0.19 mm. Grade KC5010 targets steel and cast iron applications where wear resistance and edge stability are priorities. Machinists and toolroom technicians install this insert as a direct component in compatible Top Notch toolholders.

This insert is suited for grooving, parting, and profiling operations in production and job-shop turning environments. It is sized at NG2062 and fits into Top Notch series toolholding systems designed for that insert style. The neutral rake geometry and 55-degree included angle make it appropriate for a range of workpiece materials classified under carbide material grades C3 and C4. It is intended for use in operations where cutting width precision and controlled depth of cut are critical to part quality.

Compatibility

Designed for use in Top Notch series toolholders accepting NG2062-style inserts. Consult the toolholder manufacturer specifications to confirm seat geometry and clamping compatibility before installation.

Installation Notes

This insert is installed by qualified machinists or toolroom technicians on CNC or manual turning equipment. Power down and lock out the machine before seating or replacing the insert. Ensure the insert pocket and clamping surfaces are clean and free of chips before installation. Do not exceed the rated maximum depth of cut for the insert size, and verify that the toolholder is rated for the intended cutting parameters.
