Kennametal 1113027 Grooving Insert NG2125 KC730 Carbide

Product Description

The KENNAMETAL 1113027 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 features a KC730 grade substrate with a PVD-applied TiN coating, delivering improved wear resistance and edge retention in interrupted and continuous cuts. The insert has a cutting width of 0.1252 inches (3.18 mm) and a maximum depth of cut of 0.1098 inches (2.79 mm). The right-hand orientation and NG2125 insert style make it a direct fit for compatible Top Notch toolholders. This insert is installed by machinist-level operators and CNC setup technicians in precision metal removal applications.

This insert is suited for grooving operations on ferrous and non-ferrous materials, targeting material grades C2, C3, and C4. It performs in applications requiring a 3-degree lead angle and a neutral rake geometry, with a 55-degree included angle and a 0.0075-inch (0.19 mm) corner radius. Typical use cases include external grooving, undercutting, and profiling on production turning machines in job shop and manufacturing environments. It is not a multi-use insert and is intended for dedicated grooving applications within the specified depth of cut range of 0.1000 to 0.1500 inches (2.00 to 3.00 mm).

Compatibility

Designed for use with Top Notch series toolholders accepting the NG insert style. The MSC and manufacturer cross-reference number for this insert is NG2125R/L. Confirm toolholder compatibility by insert style, cutting width, and hand orientation before installation.

Installation Notes

Installation is performed by qualified machinists or CNC technicians. Power down and lock out the machine spindle before seating or removing the insert. Ensure the insert pocket is clean and free of chips or debris before clamping. Do not exceed the maximum depth of cut specification for the insert grade and coating.
