Kennametal 1817720 Grooving Insert NG2041 KC5025 Carbide

Product Description

The KENNAMETAL 1817720 is a solid carbide grooving insert designed for precision external and internal grooving operations on CNC lathes and turning centers. Manufactured to the NG2041 insert style within the Top Notch series, it carries a PVD-applied TiAlN coating and a KC5025 grade designation, which is suited for a wide range of ferrous and difficult-to-machine materials. The insert has a cutting width of 1.04 mm and a maximum depth of cut of 1.27 mm. The left-hand orientation and neutral rake geometry make it appropriate for specific toolholder configurations where approach direction and chip flow are critical. Machinists and CNC tooling specialists are the primary installers.

This insert is suited for grooving, parting, and profile turning applications where tight groove width tolerances are required. The 1.04 mm cutting width and 0.09 mm corner radius support fine-feature grooving on small-diameter workpieces typical in precision machining, medical component manufacturing, and aerospace part production. It is designed for use in Top Notch series toolholders that accept the NG2041 insert size. Its PVD TiAlN coating provides thermal resistance and wear life at elevated cutting speeds.

Key Features

• Solid carbide construction with PVD TiAlN coating for extended wear resistance at high cutting temperatures
• KC5025 grade — suitable for a broad range of ferrous and hard-to-machine workpiece materials
• 1.04 mm cutting width for precision narrow-groove applications
• Maximum depth of cut of 1.27 mm within a range up to 2.00 mm
• Left-hand, neutral rake geometry for specific toolholder approach configurations
• 0.09 mm corner radius and 55-degree included angle support fine feature definition
• Top Notch series compatibility ensures secure insert seating and repeatable indexing

Compatibility

Designed for use in Top Notch series toolholders that accept the NG2041 insert size and are configured for left-hand cutting orientation.

Installation Notes

This insert is installed by machinists or CNC tooling technicians during machine setup or insert indexing. The machine spindle must be fully stopped and all motion axes locked before removing or seating the insert. Use the appropriate torque wrench or clamping key specified by the toolholder manufacturer to secure the insert clamp — do not overtighten by hand. Verify insert seating and orientation against the toolholder drawing before resuming cutting operations.
