Kennametal 1818504 Grooving Insert NG3072K KC5010 Carbide

Product Description

The KENNAMETAL 1818504 is a solid carbide grooving insert carrying the NG3072K geometry and KC5010 manufacturer grade. It features a Physical Vapor Deposition (PVD)-applied TiAlN coating that provides thermal resistance and wear protection during interrupted cuts and continuous grooving operations. The insert has a right-hand orientation, a 1.83 mm cutting width, and a maximum depth of cut of 2.39 mm. The positive rake angle of 10 degrees and the K chip breaker geometry promote controlled chip formation and reduce cutting forces. Licensed machinists and CNC lathe operators working in production environments are the primary installers and users of this insert.

This insert is designed for external grooving, parting, and turning applications on CNC lathes and turret lathes. It belongs to the Top Notch series and is suited for machining steel and cast iron workpiece materials consistent with the C3 and C4 material grades. The 55-degree included angle and a corner radius of 0.19 mm make it appropriate for close-tolerance groove profiles in medium to high-volume production runs. It is sold individually with a minimum order quantity of 5 units per purchase.

Key Features

• Solid carbide construction with PVD TiAlN coating for extended tool life and heat resistance
• 1.83 mm cutting width with a maximum depth of cut of 2.39 mm
• Right-hand insert orientation for standard external grooving setups
• Positive 10-degree rake angle reduces cutting forces and improves chip flow
• K chip breaker geometry promotes reliable chip control at the groove face
• Corner radius of 0.19 mm supports precise groove profile tolerances

Compatibility

Designed as a Top Notch series grooving insert compatible with Top Notch-style toolholders and grooving systems that accept the NG insert style and size 3072 geometry.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the turret is in a safe index position before seating or replacing the insert. Use the appropriate torque wrench and clamp screws specified for the Top Notch toolholder to secure the insert without over-tightening. Inspect the insert seat and clamping surfaces for chips or debris before each insert change to maintain accurate seating and runout.
