Kennametal 1818833 Grooving Insert NR3094 KC5025 Carbide

Product Description

The KENNAMETAL 1818833 is a solid carbide grooving insert in the Top Notch series, designed for turning and grooving operations on CNC lathes and turning centers. It carries a TiAlN coating applied via PVD process, which provides thermal resistance and extended tool life in demanding cutting applications. The insert is left-hand oriented with a 4.78 mm cutting width, a maximum depth of cut of 3.81 mm, and a full radius corner measuring 2.39 mm. Grade KC5025 is suited for a range of workpiece materials across C2 and C6 material grades. Machinists and CNC operators working in precision turning applications will recognize this insert as a direct-fit Top Notch system component.

This insert is intended for use in grooving and cutoff operations on CNC turning equipment. The neutral rake geometry and full radius profile make it well suited for external grooving on ferrous and non-ferrous workpieces where a consistent, radiused groove floor is required. The 55-degree included angle and metric sizing (Insert Size 3094) place it firmly in finish and semi-finish grooving applications. It is sold individually and must be ordered in multiples of 5 per the manufacturer minimum order requirement.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician with the machine fully stopped and in a safe, locked-out state before insert changes are made. Use the appropriate torque wrench and insert clamp hardware specified for Top Notch series toolholders — do not over-tighten or substitute fasteners. Inspect the pocket seat and clamp for debris or wear before seating the new insert. Confirm insert orientation (left-hand) matches the programmed toolpath direction before resuming operation.
