Kennametal 1818768 Grooving Insert NG3094K KC5025 Tialn

Product Description

The KENNAMETAL 1818768 is a solid carbide grooving insert designed for precision grooving operations on CNC lathes and turning centers. Manufactured to the NG3094K geometry in grade KC5025, this insert features a TiAlN coating applied via PVD process, delivering excellent wear resistance and thermal stability during interrupted and continuous cuts. It is configured for left-hand orientation with a 2.39 mm cutting width and a maximum depth of cut of 3.81 mm. A positive rake angle of 10 degrees and a K-style chip breaker promote controlled chip evacuation in a wide range of workpiece materials. Machinists and toolroom technicians working in production turning applications select this insert for consistent groove geometry and dimensional repeatability.

This insert fits within the Top Notch series tooling system and is suited for grooving, recessing, and light parting operations on ferrous and non-ferrous materials. The KC5025 grade, rated C2 and C6, is appropriate for applications where both toughness and coating-assisted surface protection are required. It is typically installed in a compatible Top Notch toolholder on manual or CNC turning equipment in job shops, production facilities, and maintenance machining environments.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist following the toolholder manufacturer's torque and clamping procedures. Power down and lock out the machine spindle before changing inserts. Inspect the toolholder pocket for debris, wear, or damage prior to seating the new insert. Do not attempt to regrind or recoat this insert in the field.
