Kennametal 5968034 Grooving Insert NG3K KCP25B Left Hand

Product Description

The KENNAMETAL 5968034 is a solid carbide grooving insert in the NG3K style, designed for precision grooving and parting operations on CNC lathes and turning centers. It carries the KCP25B grade with a CVD-applied TiOCN coating, which provides wear resistance and thermal stability across a range of workpiece materials. The insert features a left-hand orientation, a 2.39 mm cutting width, and a maximum depth of cut of 3.81 mm. A positive rake angle of 3 degrees and K-style chip breaker geometry promote clean chip evacuation and reduced cutting forces. This insert is installed by machinists and CNC turning technicians in production and job-shop environments.

This insert is suited for external grooving, face grooving, and light parting applications in both production and precision machining environments. The Top Notch series uses a clamp-style insert holding method, making indexing straightforward at the machine. The KCP25B grade is positioned for general-purpose turning and grooving in steels and cast irons where CVD-coated carbide is the appropriate tooling choice. The 0.19 mm corner radius and insert size 3 designation are standard reference points when selecting compatible toolholders within the Top Notch platform.

• Insert size 3, metric measurement type, compatible with 3/8 inch gage diameter toolholders

Compatibility

Designed for use with Top Notch series clamp-style toolholders accepting an NG insert style, insert size 3, with a 3/8 inch gage diameter. Specific compatible toolholder part numbers were not provided in the available product data; consult KENNAMETAL toolholder selection guides for confirmed pairings.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or CNC tooling technician with the machine in a full stop and all axes locked. Use the appropriate Top Notch clamp key or torque wrench per the toolholder manufacturer's seating procedure. Inspect the insert pocket and clamping screw for wear or contamination before seating a new insert. Do not exceed the maximum depth of cut specified for this insert grade and geometry.
