Kennametal 1818437 Grooving Insert NP3002K KC5010

Product Description

The KENNAMETAL 1818437 is a solid carbide grooving insert designed for precision external grooving operations on CNC lathes and turning centers. Belonging to the Top Notch series, this right-hand insert features a TiAlN PVD coating over a KC5010 carbide grade substrate, delivering wear resistance and thermal stability in demanding cutting environments. It carries a 4.83 mm (0.190 inch) cutting width and supports a maximum depth of cut of 5.08 mm (0.200 inch). The positive rake geometry and 10-degree rake angle reduce cutting forces and promote clean chip evacuation. Machinists and CNC operators working in job shops and production turning environments rely on this insert for repeatable groove profiles in ferrous and non-ferrous materials.

This insert is suited for external grooving applications on turning centers where dimensional consistency and surface finish are priorities. The NP insert style and Top Notch series toolholding system make it compatible with corresponding Top Notch grooving toolholders. Typical applications include groove turning on shafts, spacers, and cylindrical components in medium to high production runs. The K chip breaker geometry is optimized for controlled chip formation at moderate feed rates and depths, making it practical for both roughing and semi-finishing groove passes within its rated depth range.

Key Features

• KC5010 carbide grade with TiAlN PVD coating for extended tool life in abrasive and elevated-temperature cuts
• 4.83 mm (0.190 inch) cutting width for precise, consistent groove sizing
• Maximum depth of cut of 5.08 mm (0.200 inch); rated depth-of-cut range extends to 10.00 mm
• Positive rake angle of 10 degrees reduces cutting forces and heat generation
• K chip breaker geometry for controlled chip formation in medium-duty grooving
• Corner radius of 0.09 mm (0.0035 inch) for sharp groove-bottom definition
• Right-hand insert orientation for standard lathe setups

Compatibility

Designed for use with Top Notch series grooving toolholders that accept the NP3002K insert style. Verify toolholder seat geometry and insert size designation before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine before seating or removing inserts. Use the appropriate torx or hex key as specified by the toolholder manufacturer to achieve proper clamping without over-torquing the insert screw. Confirm insert seating and clearance before resuming cutting operations.
