Kennametal 1114334 NG3062K KC730 Grooving Insert Left Hand

Product Description

The KENNAMETAL 1114334 is a solid carbide grooving insert in the Top Notch series, designed for precision external grooving and profiling on CNC lathes and turning centers. It carries the NG3062K form factor with a KC730 grade and a PVD-applied TiN coating, which improves wear resistance and extends tool life in a range of ferrous and non-ferrous applications. The insert has a left-hand orientation, a 1.58 mm cutting width, and a maximum depth of cut of 2.39 mm. A positive rake angle of 10 degrees reduces cutting forces and improves chip flow. Installed by machinists and CNC operators in production and job-shop environments.

This insert is suited for grooving operations on small to medium-diameter workpieces in both production turning and general machining environments. The K chip breaker geometry supports controlled chip formation in a variety of materials. Material grade compatibility covers C2, C3, and C4 carbide application ranges, making it appropriate for cast iron, non-ferrous metals, and non-metallic materials. The 55-degree included angle and 3-degree lead angle support accurate groove geometry. Insert size designation is 3062, consistent with Top Notch toolholder systems that accept this form factor.

Key Features

• PVD TiN coating for improved wear resistance and surface finish
• Left-hand cutting orientation for specific toolholder configurations
• 1.58 mm cutting width with a maximum depth of cut of 2.39 mm
• Positive rake angle (10 degrees) reduces cutting forces and aids chip evacuation
• K chip breaker geometry for predictable chip control
• Corner radius of 0.19 mm for controlled groove edge geometry

Compatibility

Designed for use with Top Notch series toolholders that accept the NG-style insert in size 3062. Compatible with material grades C2, C3, and C4 application categories.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator with the machine powered down and all axes at rest. Seat the insert fully in the toolholder pocket and torque the clamping screw according to the toolholder manufacturer specification. Inspect the insert seat for chips or debris before installation, as an unseated insert can fracture under cutting loads. Verify left-hand orientation matches the toolholder before starting the machine.
