Kennametal 1818835 Grooving Insert NR3094 KC5025 Carbide

Product Description

The KENNAMETAL 1818835 is a solid carbide grooving insert designed for precision external grooving and parting operations on CNC lathes and turning centers. Manufactured to the Top Notch series standard with a KC5025 grade substrate and a PVD-applied TiAlN coating, this insert delivers wear resistance and thermal stability across a range of ferrous and non-ferrous materials. The right-hand insert features a 4.78 mm cutting width and a maximum depth of cut of 3.81 mm, making it well suited to medium-duty grooving applications. Machinists and tooling technicians working in production environments are the primary users.

This insert is intended for use in Top Notch series grooving toolholders on turning and OD grooving applications. It is suited for shops running metric-dimensioned programs where consistent groove width and depth control are required. The full-radius geometry with a 2.39 mm corner radius and a 55-degree included angle support smooth chip flow and groove floor finish. It is appropriate for both job-shop and production-volume turning environments.

Installation Notes

Insert installation and replacement should be performed by a qualified machinist or tooling technician with the machine in a powered-down, locked-out state. Seat the insert firmly in the pocket and tighten the clamping screw to the toolholder manufacturer's specification before engaging a cut. Inspect the insert pocket and clamping components for wear or debris before seating a new insert. Do not exceed the maximum depth of cut rating for this insert grade and geometry.
