Kennametal 2598816 Grooving Insert NGP3125 KC5010

Product Description

The KENNAMETAL 2598816 is a solid carbide grooving insert in the Top Notch series, designed for precision external grooving and parting operations on CNC lathes and turning centers. This insert carries the NGP style designation with a KC5010 grade and a PVD-applied TiAlN coating, making it well suited for interrupted cuts and materials requiring a tough, wear-resistant edge. The right-hand cutting configuration, 0.1252 inch (3.18 mm) cutting width, and a maximum depth of cut of 0.1500 inch (3.81 mm) define its primary operating envelope. Installed by machinists and toolroom technicians, it fits standard Top Notch toolholders and delivers consistent groove geometry in production environments.

This insert is intended for grooving applications in metalworking operations, typically on CNC turning equipment in job shops, production machining cells, and maintenance repair environments. Its positive rake angle of 5 degrees reduces cutting forces, making it appropriate for medium to finish grooving passes on ferrous and non-ferrous materials classified under material grades C3 and C4. The 55-degree included angle and 0.0075 inch (0.19 mm) corner radius contribute to controlled chip formation and groove-wall definition. It is sold individually but requires a minimum order quantity of 5 units.

Key Features

• Solid carbide construction with PVD TiAlN coating for wear resistance and thermal stability
• KC5010 grade optimized for consistent edge life in grooving and parting applications
• 3.18 mm (0.1252 inch) cutting width with a maximum depth of cut of 3.81 mm (0.1500 inch)
• Positive rake angle (5 degrees) reduces cutting forces and improves chip flow
• Right-hand cutting orientation for standard Top Notch toolholder setups
• Corner radius of 0.19 mm (0.0075 inch) for precise groove-wall profiling

Compatibility

Designed as a Top Notch series replacement grooving insert compatible with standard Top Notch style toolholders accepting the NGP3125 insert size.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. The machine spindle must be stopped and all stored energy discharged before indexing or replacing inserts. Seat the insert fully into the toolholder pocket and verify clamping torque per the toolholder manufacturer specifications before resuming cuts. Do not exceed the rated maximum depth of cut for this insert style, and inspect the cutting edge for chipping or wear at regular intervals.
