Kennametal 2599744 Grooving Insert NG2041 KC5010 Carbide

Product Description

The KENNAMETAL 2599744 is a solid carbide grooving insert designed for precision external grooving operations on CNC lathes and turning centers. Manufactured to the NG2041 insert style within the Top Notch series, this left-hand insert features a TiAlN coating applied via PVD process, delivering excellent wear resistance and thermal stability at elevated cutting speeds. The cutting width measures 1.04 mm with a maximum depth of cut of 1.27 mm, making it well suited for tight-tolerance groove profiles in medium to hard workpiece materials. Machinists and CNC operators working in production turning environments rely on this insert for repeatable, consistent grooving performance.

This insert is intended for use in external grooving and parting applications on CNC turning machines and manual lathes equipped with Top Notch series toolholders. The NG insert style with a neutral rake geometry and a 0.09 mm corner radius suits applications requiring close groove tolerances in steel, alloy steel, and similarly classified C3 and C4 material grades. It is a single-piece insert sold individually, with a minimum order quantity of 5 units, making it appropriate for shop stock replenishment in job shops and production turning facilities.

Compatibility

Designed for use with Top Notch series grooving toolholders that accept the NG2041 insert style. Verify toolholder insert pocket specifications before installation.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before changing inserts. Ensure the insert pocket is clean and free of chips or debris before seating the insert. Verify clamping screw torque per the toolholder manufacturer specifications rather than estimating by feel.
