Kennametal 1113824 NR3031 KC850 Grooving Insert Carbide

Product Description

The KENNAMETAL 1113824 is a solid carbide grooving insert designed for precision external grooving and parting operations on CNC lathes and turning centers. Built to the Top Notch series standard, this insert carries a CVD-applied multilayer coating of TiC, TiCN, and TiN for wear resistance and thermal stability at the cutting edge. The insert is sized NR3031 with a 1.58 mm cutting width and a maximum depth of cut of 2.39 mm, making it well suited for shallow groove profiles. Manufacturer grade KC850 targets steel and cast iron cutting at moderate to high speeds. The insert features a full radius corner at 0.79 mm and a neutral rake geometry.

This insert is intended for use in turning centers and CNC lathes performing external grooving, necking, and light parting operations. It is configured for right-hand cutting and is sold individually per package, with a minimum order of 5 units. The neutral rake and full radius profile suit applications where groove floor finish and dimensional consistency are critical. Machinists and CNC operators working in job shops, production turning, and maintenance machining environments are the primary users of this insert.

Compatibility

Designed as a Top Notch series replacement insert compatible with KENNAMETAL Top Notch grooving toolholders accepting NR3031 inserts. Refer to your toolholder documentation to confirm seat and clamp compatibility before installation.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Power down and lock out the machine spindle before seating or removing any insert. Seat the insert fully into the Top Notch pocket and confirm the clamp engages the notch before resuming cuts. Do not exceed the maximum depth of cut specification for this insert style, as overloading a grooving insert can cause sudden fracture.
