Kennametal 2599524 Grooving Insert NG3094 KC5025 Carbide

Product Description

The KENNAMETAL 2599524 is a solid carbide grooving insert in the Top Notch series, engineered for precision external grooving and profiling operations on CNC turning centers and manual lathes. This left-hand insert carries a TiAlN coating applied via PVD process, which provides thermal resistance and extended tool life in a wide range of workpiece materials. The insert delivers a cutting width of 2.39 mm (0.0941 inches) and a maximum depth of cut of 3.81 mm (0.150 inches), with a neutral rake geometry and a corner radius of 0.19 mm (0.0075 inches). It is intended for installation by machinists and toolroom professionals working to tight groove tolerances.

This insert is suited for grooving applications in ferrous and non-ferrous materials where a left-hand cutting direction is required. The NG-style insert seats in compatible Top Notch toolholders. At the KC5025 grade with a 55-degree included angle and a lead angle of 3 degrees, it performs reliably in both light finishing and moderate material-removal grooving passes. Typical environments include production turning cells and job shop lathe operations requiring repeatable groove geometry and consistent surface finish.

Key Features

• Solid carbide substrate at manufacturer grade KC5025 for wear resistance and edge stability
• TiAlN PVD coating for elevated-temperature performance and extended tool life
• Cutting width of 2.39 mm (0.0941 inches) for precise groove sizing
• Maximum depth of cut range of 3.00 mm to 4.00 mm (0.150 to 0.200 inches)
• Neutral rake geometry with 0.19 mm corner radius for controlled chip formation
• Left-hand cutting orientation for specific toolholder and application requirements

Compatibility

Designed for use in Top Notch series toolholders accepting the NG insert style at insert size 3094. Verify toolholder compatibility by confirming the NG seating geometry and insert size designation before installation.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist with the machine powered down and the spindle locked. Use the correct torque driver specified by the toolholder manufacturer when securing the clamping screw — do not use impact tools. Inspect the insert pocket for chips or debris before seating the insert to ensure full contact and repeatable tool geometry. Confirm left-hand orientation matches the intended cutting direction before beginning the operation.
