Kennametal 1112964 Grooving Insert NR2062 KC730 Carbide

Product Description

The KENNAMETAL 1112964 is a solid carbide grooving insert in the NR2062 style, designed for precision grooving and parting operations on CNC lathes and turning centers. Manufactured to the KC730 grade with a PVD-applied TiN coating, this insert delivers consistent wear resistance and edge integrity at the cutting zone. The right-hand configuration and neutral rake geometry make it well suited for standard external grooving applications. At 3.18 mm cutting width and a maximum depth of cut of 2.79 mm, it handles shallow-to-moderate groove profiles with full-radius cutting action across a 1.59 mm corner radius.

This insert is part of the Top Notch series and is intended for use in compatible Top Notch toolholders on production turning equipment. It is appropriate for grooving operations on materials falling within the C2, C3, and C4 material grades, covering a broad range of cast irons and non-ferrous alloys. Machinists and CNC operators in job shop and production environments use this insert for groove widths requiring tight dimensional control. The full-radius profile supports consistent chip control and smooth groove floor geometry in repetitive cutting cycles.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or CNC operator with the machine fully powered down and the spindle locked. Use the appropriate Top Notch clamp screw and torquing tool as specified by the toolholder manufacturer. Inspect the insert pocket and clamping components for debris or wear before seating a new insert. Confirm insert orientation matches the right-hand designation of the toolholder before resuming operation.
