Kennametal 1818371 Grooving Insert NG3062K KC5025 Left Hand

Product Description

The KENNAMETAL 1818371 is a solid carbide grooving insert designed for precision parting and grooving operations on CNC lathes and turning centers. It carries the NG3062K insert style designation within the Top Notch series and is finished with a PVD-applied TiAlN coating for improved heat and wear resistance. The insert features a 1.58 mm cutting width, a maximum depth of cut of 2.39 mm, and a positive rake angle of 10 degrees, making it suited for controlled chip formation in finish and semi-finish grooving passes. It is configured for left-hand orientation. This insert is installed by machinists and CNC turning specialists in production and job-shop environments.

The 1818371 is applied in external grooving and parting operations where tight dimensional control and surface finish are required. The K chip breaker geometry and positive rake support clean chip evacuation in materials within the C2 and C6 material grade range. The 55-degree included angle and 0.19 mm corner radius allow for precise groove profile definition. This insert is sold individually and must be ordered in multiples of five to meet the minimum order quantity requirement.

Installation Notes

This insert is seated and secured by a qualified machinist or CNC tooling technician following the toolholder manufacturer's clamping procedure. Power down and lock out the spindle before changing inserts. Do not exceed the recommended maximum depth of cut range of 2.00 mm to 3.00 mm for this insert size. Inspect the insert seat and clamping screw for wear or debris before seating a new insert to ensure proper contact and repeatability.
