Kennametal 1114281 Grooving Insert KC730 1.4mm Right Hand

Product Description

The KENNAMETAL 1114281 is a solid carbide grooving insert designed for precision external grooving and parting operations on CNC lathes and turning centers. It carries a KC730 grade designation with a PVD-applied TiN coating, which provides wear resistance on a range of workpiece materials. The insert has a 1.4 mm cutting width and a maximum depth of cut of 1.27 mm, making it suited for narrow, shallow groove profiles. The positive rake geometry and K-style chip breaker promote controlled chip evacuation and reduced cutting forces. This insert is sold individually and is intended for installation by machinists and CNC turning technicians.

This insert belongs to the Top Notch series and is configured for right-hand cutting. It fits grooving toolholders designed for the Top Notch NG insert style. Typical applications include finish grooving, O-ring groove preparation, and light parting on ferrous and nonferrous materials. The KC730 grade, classified under material grades C2, C3, and C4, is appropriate for general-purpose turning of steel, cast iron, and similar materials. The 10-degree rake angle and 55-degree included angle geometry support clean entry and exit in tight groove profiles.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and all power is locked out before seating or removing the insert. Verify the toolholder pocket and clamping mechanism are clean and free of chips before installing. Follow the toolholder manufacturer torque specifications for the clamping screw, and confirm insert seating before resuming cutting operations.
