Kennametal 1818359 Grooving Insert NGD4189K KC5010

Product Description

The KENNAMETAL 1818359 is a solid carbide grooving insert designed for precision external grooving and parting operations on CNC lathes and turning centers. Built to the Top Notch series standard, it carries the NGD insert style with a KC5010 manufacturer grade and a PVD-applied TiAlN coating for extended tool life in demanding cutting conditions. The insert is left-hand oriented, with a 4.8 mm cutting width and a maximum depth of cut of 9.53 mm. A 0.57 mm corner radius and a positive 10-degree rake angle support controlled chip formation. This insert is sold individually and requires a minimum order of 5 units.

This insert is suited for turning operations involving groove profiling, face grooving approaches, and parting on ferrous and non-ferrous workpiece materials where a C3 or C4 carbide grade is appropriate. The TiAlN PVD coating provides heat and oxidation resistance, making it a practical choice for dry or semi-dry cutting environments. It is installed by machinists and CNC tooling technicians in job shop and production turning applications where precise groove geometry and consistent depth control are required.

Key Features

• Left-hand insert orientation for correct clearance in left-hand toolholder setups
• 0.57 mm corner radius and 55-degree included angle for defined groove geometry

Compatibility

Designed for use with Top Notch series grooving toolholders that accept size 4 insert seats and NGD-style inserts. Verify toolholder insert seat size and hand orientation before installation.

Installation Notes

This insert is installed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or removing inserts. Use the correct Top Notch clamp and torque the clamping screw with the manufacturer-specified insert key — do not overtighten by hand tools not rated for the seat. Confirm left-hand orientation matches the toolholder before initiating a cut.
