Kennametal 1114264 NRP3047 KC730 Grooving Insert

Product Description

The KENNAMETAL 1114264 is a solid carbide grooving insert designed for precision turning and grooving operations on CNC lathes and other turning centers. Built to the NRP3047 style in the KC730 grade, it features a PVD-applied TiN coating that extends cutting edge life across a range of workpiece materials. The insert has a 2.39 mm cutting width, a maximum depth of cut of 3.81 mm, and a full-radius corner profile with a 1.19 mm corner radius. A positive 5-degree rake angle promotes free cutting and reduces cutting forces. This insert is part of the Top Notch series and is intended for installation by machinists and toolroom technicians working in production or job-shop environments.

This insert is suited for grooving, parting, and profile turning applications where consistent width and depth control are required. The right-hand orientation fits standard Top Notch toolholders configured for right-hand cutting. It is appropriate for use on ferrous and non-ferrous materials corresponding to C2, C3, and C4 material grades. The metric sizing and 55-degree included angle make it well-matched to applications where fine surface finish and controlled chip formation are priorities in medium-duty turning operations.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician with the machine spindle fully stopped and all stored energy released. Use the appropriate torque wrench and seating tool recommended for Top Notch insert pockets to avoid edge chipping during clamping. Inspect the toolholder pocket for wear or debris before seating the insert. Do not exceed the rated maximum depth of cut for the insert grade and workpiece material combination in use.
