Kennametal 1818440 Grooving Insert NPD2002K KC5010 Carbide

Product Description

The KENNAMETAL 1818440 is a solid carbide grooving insert in the Top Notch series, designed for precision grooving and parting operations on CNC lathes and turning centers. It carries a TiAlN finish applied via PVD coating, which provides heat resistance and extended tool life in steel and cast iron applications. The insert is right-hand oriented with a 3.68 mm cutting width (0.1449 inch) and a maximum depth of cut of 5.08 mm (0.2000 inch). The KC5010 grade is a PVD-coated carbide grade suited for finishing to medium roughing cuts. Licensed machinists and CNC operators install this insert as a direct replacement in compatible Top Notch toolholders.

This insert is intended for use in turning and grooving applications on production and job-shop lathes. It fits Top Notch series toolholders and is well suited for grooving external diameters, undercutting, and light parting on ferrous and non-ferrous workpieces. The positive rake geometry and K chip breaker design help control chip flow in moderate-to-deep groove passes. The insert size designation is 2002, and the manufacturer part number as stamped on the insert body is NPD2002RK. It is sold individually but subject to a minimum order quantity of 5 units.

Compatibility

Designed for use with Top Notch series grooving toolholders. Verify toolholder seat geometry and insert size designation 2002 compatibility before installation. No additional specific model compatibility data was provided in the product input.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or removing inserts. Use the appropriate torx or hex key as specified by the toolholder manufacturer to achieve proper clamping force without over-torquing the clamp screw. Inspect the toolholder seat for chips or debris before seating the insert to ensure full, flat contact and accurate cutting geometry.
