Kennametal 2599526 Grooving Insert NG3156 KC5025 Carbide

Product Description

The KENNAMETAL 2599526 is a solid carbide grooving insert in the Top Notch series, designed for precision grooving and turning operations on CNC lathes and turning centers. It carries a TiAlN coating applied via PVD process, which provides high heat resistance and wear protection during interrupted cuts and high-speed applications. The insert delivers a cutting width of 3.96 mm (0.1559 inches) and a maximum depth of cut of 3.81 mm (0.1500 inches), making it well suited for shallow to medium-depth grooving passes. It features a neutral rake geometry and a right-hand cutting orientation. Machinists and tooling specialists working in production turning environments select this insert for its consistent dimensional performance and coating durability.

This insert is intended for grooving and profiling operations on metalworking lathes in both job shop and production settings. The NG-style insert seats into compatible Top Notch toolholders. The KC5025 grade with TiAlN PVD coating is commonly applied to machining steel, stainless steel, and cast iron workpieces where edge toughness and thermal resistance are priorities. The 55-degree included angle and 0.19 mm corner radius support controlled chip formation on finish and semi-finish grooving passes.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist or tooling technician following the toolholder manufacturer's torque specifications. Power down and lock out the machine spindle before changing inserts. Inspect the insert pocket for chips or debris before seating the insert, and verify clamping screw engagement before resuming cuts. Do not exceed the rated maximum depth of cut range of 3.00 mm to 4.00 mm for this insert style.
