Kennametal 1818769 Grooving Insert NG3094K KC5025 Carbide

Product Description

The KENNAMETAL 1818769 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 the KC5025 grade with a PVD-applied TiAlN coating, which provides wear resistance and thermal stability during interrupted cuts and high-speed passes on steel and cast iron workpieces. The insert features a right-hand orientation, a 2.39 mm cutting width, and a maximum depth of cut of 3.81 mm. A positive rake angle of 10 degrees and the K chip breaker geometry combine to promote efficient chip evacuation and reduced cutting forces. This insert is sized in the 3094 format and is installed by machinists and CNC toolroom technicians.

This insert is suited for precision grooving applications in both production and job-shop environments where consistent groove width and depth control are required. It is appropriate for use on carbon steel, alloy steel, and cast iron at moderate to high cutting speeds. The 55-degree included angle and 0.19 mm corner radius make it well suited for tight-tolerance groove profiles in residential, commercial, and industrial component manufacturing. Compatible toolholders in the Top Notch series accept this NG-style insert geometry directly.

Installation Notes

Installation is performed by a qualified machinist or CNC toolroom technician. Power down and lock out the machine spindle before seating or replacing the insert. Ensure the toolholder pocket and clamping surfaces are clean and free of chips before inserting to prevent seating errors. Follow the toolholder manufacturer torque guidelines for the clamping screw and verify insert orientation before resuming operation.
