Kennametal 1114329 Grooving Insert KC730 Carbide Tin Left Hand

Product Description

The KENNAMETAL 1114329 is a solid carbide grooving insert in the Top Notch series, designed for external grooving and parting operations on CNC lathes and turning centers. It carries the KC730 manufacturer grade with a PVD-applied TiN coating, delivering wear resistance on a range of workpiece materials. The insert is left-hand oriented with a 3.00 mm cutting width, a maximum depth of cut of 3.81 mm, and a positive 10-degree rake angle. The K chip breaker geometry controls chip flow during interrupted and continuous grooving cuts. Machinists and CNC operators install this insert into compatible Top Notch toolholders for precision groove profiling.

This insert is suited for production turning environments where consistent groove geometry is required. The NG style, 3M300 insert size, and left-hand orientation target grooving applications on ferrous and non-ferrous workpieces within material grades C2, C3, and C4. The 0.19 mm corner radius and 55-degree included angle support controlled groove profiles in both light and moderate cutting conditions. It is a single-use, non-multi-use insert intended for indexed replacement when worn.

Key Features

• Positive rake angle of 10 degrees reduces cutting forces during grooving
• K chip breaker geometry for controlled chip evacuation
• Left-hand insert orientation for right-to-left grooving operations
• 0.19 mm corner radius supports precise groove profile tolerances

Compatibility

Designed for use with Top Notch series toolholders accepting NG style inserts with a 3M300 insert size. Compatible with workpiece material grades C2, C3, and C4 as specified by the manufacturer.

Installation Notes

This insert is installed and replaced by a machinist or CNC operator. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench and clamping hardware specified for the Top Notch toolholder to seat the insert securely. Handle carbide inserts with care to avoid chipping the cutting edge prior to use.
