Kennametal 1112963 Grooving Insert NR2047 KC730 Carbide

Product Description

The KENNAMETAL 1112963 is a solid carbide grooving insert in the Top Notch series, designed for external grooving and parting operations on CNC lathes and turning centers. The insert features a KC730 grade carbide substrate with a PVD-applied TiN coating, delivering wear resistance and thermal stability during interrupted or continuous cuts. With a 2.39 mm cutting width and a maximum depth of cut of 2.79 mm, this right-hand insert suits precision grooving in steel, cast iron, and non-ferrous alloys. Machinists and toolroom technicians select this insert for its consistent geometry and reliable tool life in production turning environments.

This insert is intended for use in compatible Top Notch series grooving toolholders on manual and CNC turning equipment. It is suited for both light-production and high-volume turning applications where controlled groove width and depth are critical. The NR insert style with a neutral rake and full radius geometry makes it appropriate for grooving operations where burr control and surface finish at the groove base are priorities. Typical applications include grooving on shafts, hydraulic components, and precision turned parts in general machining and job shop settings.

Key Features

• KC730 grade solid carbide with PVD TiN coating for extended wear resistance
• 2.39 mm cutting width for consistent, repeatable groove dimensions
• Maximum depth of cut of 2.79 mm suited to shallow-to-mid-depth grooving
• Full radius corner geometry at 1.19 mm corner radius for smooth groove base finish
• Right-hand, neutral rake NR insert style in the Top Notch series
• Included angle of 55 degrees for positive tool engagement geometry

Compatibility

Designed as an OEM-style replacement insert for compatible Top Notch series grooving toolholders accepting NR2047 insert style geometry.

Installation Notes

This insert is installed by a machinist or toolroom technician into a compatible Top Notch series grooving toolholder. Power down and lock out the machine spindle before changing inserts. Use the appropriate torque wrench and insert clamp hardware specified for the toolholder — do not overtighten the clamping screw, as this can fracture the carbide. Inspect the insert seat and clamping components for wear or debris before seating the new insert.
