Kennametal 1114323 Grooving Insert NGD3062K KC730

Product Description

The KENNAMETAL 1114323 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 features a 1.58 mm cutting width and a maximum depth of cut of 3.18 mm, making it well suited for precision grooving in medium to hard workpiece materials. The insert carries a TiN coating applied via PVD process and delivers a positive rake angle of 10 degrees for reduced cutting forces. A right-hand orientation and K-style chip breaker control chip formation in continuous cutting applications. Licensed machinists and CNC operators install this insert as a standard tooling consumable.

This insert is intended for use in turning centers and CNC lathes performing grooving, parting, and profiling operations. It fits toolholders in the Top Notch series that accept the NGD insert style at size 3062. The KC730 grade is appropriate for material grade classifications C2, C3, and C4, covering a broad range of steel, cast iron, and similar workpiece materials in both roughing and finishing grooving passes. The 55-degree included angle and 3-degree lead angle support stable entry and clean groove geometry. This insert is a single-use, non-multi-use tooling component.

• K-style chip breaker promotes controlled chip evacuation in grooving applications
• Right-hand insert orientation for standard external grooving setups
• Corner radius of 0.19 mm supports clean groove floor geometry

Compatibility

Designed for use with Top Notch series toolholders that accept the NGD insert style at size 3062. Cross-reference manufacturer designation NGD3062R/LK when verifying toolholder compatibility.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician following machine lockout and spindle-stop procedures before insert indexing or replacement. Verify toolholder clamping torque per the toolholder manufacturer specifications and confirm insert seating before resuming cutting. Inspect the pocket and clamping screw for wear or contamination before installing a new insert. Follow applicable shop safety protocols and machine manufacturer guidelines for tooling changeovers.
