Kennametal 1818434 Grooving Insert NP2002K KC5010 Carbide

Product Description

The KENNAMETAL 1818434 is a solid carbide grooving insert designed for precision external grooving and parting operations on CNC lathes and turning centers. It carries the KC5010 grade with a PVD-applied TiAlN coating, which provides wear resistance and thermal stability during interrupted cuts and general turning applications. The insert features a right-hand orientation, a 3.68 mm cutting width, and a maximum depth of cut of 2.79 mm. The positive rake geometry and K-style chip breaker promote controlled chip flow and reduced cutting forces. This insert is intended for installation by machinists and tooling specialists working in precision machining environments.

This insert is part of the Top Notch series and is suited for grooving operations on steel, cast iron, and similar materials in the C3 and C4 material grade ranges. It is commonly used in production turning environments where repeatable groove geometry and insert indexability are required. The NP2002K designation identifies the insert style, size, and chip breaker configuration within the Top Notch system. A lead angle of 3 degrees and an included angle of 55 degrees support accurate groove profiling at controlled cutting depths.

Key Features

• KC5010 grade with PVD TiAlN coating for wear resistance and extended tool life
• Solid carbide construction for rigidity in demanding grooving applications
• 3.68 mm cutting width with a maximum depth of cut of 2.79 mm
• Positive rake angle of 10 degrees reduces cutting forces and promotes clean chip formation
• K-style chip breaker for controlled chip evacuation during grooving operations
• Right-hand insert orientation for standard OD grooving setups

Compatibility

Designed for use with Top Notch series toolholders that accept NP2002-style inserts. Verify holder compatibility using the NP2002RK manufacturer reference number before installation.

Installation Notes

This insert is installed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before seating or indexing any insert. Use the appropriate torx or clamp key specified by the toolholder manufacturer to secure the insert - do not overtighten by hand estimation alone. Confirm insert seating and runout before resuming cutting operations.
