Kennametal 1114303 Grooving Insert NG2031K KC730 Carbide

Product Description

The KENNAMETAL 1114303 is a solid carbide grooving insert in the Top Notch series, designed for precision grooving operations on CNC lathes and turning centers. Coated with TiN via a PVD process, this left-hand insert carries a KC730 grade designation and delivers a 0.79 mm cutting width with a maximum depth of cut of 1.27 mm. The positive rake geometry and 10-degree rake angle promote clean chip formation and reduced cutting forces. Machinists and toolroom professionals install this insert in compatible Top Notch toolholders for high-precision grooving applications.

This insert is suited for grooving operations on a range of workpiece materials corresponding to material grades C2, C3, and C4, covering cast iron, non-ferrous metals, and certain non-metallic materials. The K-style chip breaker geometry manages chip control in shallow-to-moderate depth passes. With an included angle of 55 degrees and a 3-degree lead angle, the insert is appropriate for light to medium grooving on small-diameter features where tight tolerances are required. The insert size designation is 2031, consistent with the Top Notch NG-style platform.

Key Features

• Solid carbide construction with KC730 grade for wear resistance in grooving applications
• TiN coating applied via PVD process for improved surface hardness and tool life
• 0.79 mm cutting width for narrow, precise grooves
• Maximum depth of cut of 1.27 mm, suitable for shallow groove profiles
• Positive rake angle (10 degrees) reduces cutting forces and supports clean chip evacuation
• K-style chip breaker aids chip control in short, controlled passes
• Left-hand orientation for specific toolholder and setup configurations

Compatibility

Designed for use with Top Notch series NG-style toolholders that accept the 2031 insert size. Verify toolholder hand orientation and seating pocket geometry before installation.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before seating or removing inserts. Use the appropriate torque wrench or insert-seating tool as specified by the toolholder manufacturer — do not overtighten the clamping screw. Inspect the insert pocket for debris or wear before seating a new insert to ensure proper contact and tool life.
