Kennametal 1113082 Grooving Insert NG3097 KC730 Carbide

Product Description

The KENNAMETAL 1113082 is a solid carbide grooving insert in the Top Notch series, designed for external grooving and cutoff operations on CNC lathes and turning centers. The insert features a KC730 carbide grade with a PVD-applied TiN coating, providing wear resistance and thermal stability across a range of workpiece materials. It has a left-hand cutting orientation, a 2.46 mm (0.0969 inch) cutting width, and a maximum depth of cut of 3.81 mm (0.1500 inch). The NG3097 insert style fits Top Notch-compatible toolholders. Machinists, tool-and-die technicians, and CNC operators working in production or job-shop environments install this insert as a precision cutting component in grooving and parting applications.

This insert is suited for grooving operations on ferrous and non-ferrous workpieces where controlled width and depth of cut are critical. The KC730 grade covers material grades C2, C3, and C4, making it applicable across a broad range of cast irons, steels, and similar materials in both roughing and finishing groove passes. The neutral rake geometry and 3-degree lead angle support stable chip formation during moderate to heavy grooving cuts. It is appropriate for use in both light-production and high-volume turning applications where insert consistency directly affects part tolerance.

Key Features

• 2.46 mm cutting width with maximum depth of cut up to 3.81 mm
• Left-hand cutting orientation for specific toolholder and approach configurations
• Neutral rake with 3-degree lead angle for stable, predictable chip control
• Corner radius of 0.32 mm (0.0125 inch) for controlled groove geometry
• Top Notch series insert style NG3097 for use with compatible Top Notch toolholders

Compatibility

Designed for use with Top Notch series toolholders that accept the NG insert style. Fitment is specific to left-hand Top Notch-compatible grooving toolholders designed for the NG3097 insert size.

Installation Notes

Installation is performed by machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing inserts. Seat the insert firmly in the Top Notch toolholder pocket and confirm proper clamping before returning the machine to operation. Inspect the insert pocket and clamping components for wear or debris before installation to ensure consistent seating and cutting accuracy.
