Kennametal 1114279 Grooving Insert KC730 Solid Carbide

Product Description

The KENNAMETAL 1114279 is a solid carbide grooving insert designed for precision turning and grooving operations on CNC lathes and turning centers. Belonging to the Top Notch series, this insert carries the KC730 manufacturer grade with a PVD-applied TiN coating for extended tool life in demanding cutting conditions. It is configured for right-hand cutting with a 1.00 mm cutting width and a maximum depth of cut of 1.27 mm. The positive rake angle of 10 degrees reduces cutting forces and promotes clean chip evacuation. Machinists and toolroom technicians working with materials in the C2, C3, and C4 grade ranges are the primary users of this insert.

This insert is suited for external and internal grooving, parting, and profiling applications on small-diameter features where tight tolerances and fine surface finishes are required. The K chip breaker geometry supports controlled chip formation in the 1 mm width groove envelope. Its metric-measurement design and 2M100 insert size make it appropriate for metric toolholders in both production shop and job shop environments handling light-to-medium duty grooving on ferrous and non-ferrous materials.

Key Features

• KC730 grade with PVD TiN coating for wear resistance in grooving applications
• 1.00 mm cutting width with a maximum depth of cut of 1.27 mm
• Positive 10-degree rake angle reduces cutting forces and improves chip flow
• K chip breaker geometry for controlled chip evacuation in narrow grooves
• Corner radius of 0.09 mm for precise groove profiling
• Top Notch series insert style NG for secure toolholder seating

Compatibility

Designed for use with Top Notch series toolholders accepting NG-style inserts sized 2M100. Compatible with C2, C3, and C4 material grade applications as specified by the manufacturer.

Installation Notes

Installation of grooving inserts should be performed by a qualified machinist with the machine powered off and in a locked-out state. The insert pocket and seating surfaces should be clean and free of chips or debris before seating the insert. Torque the clamping screw to the toolholder manufacturer specification using a calibrated torque wrench. Verify insert orientation for right-hand cutting before resuming machine operation.
