Kennametal 1113832 Grooving Insert NR2031 KC850 Carbide

Product Description

The KENNAMETAL 1113832 is a solid carbide grooving insert designed for precision grooving operations on CNC lathes and turning centers. Manufactured to the NR2031 style in the Top Notch series, this left-hand insert features a CVD-applied multilayer coating of TiC, TiCN, and TiN for wear resistance and extended tool life. It delivers a cutting width of 1.58 mm (0.0622 inch) and a maximum depth of cut of 2.79 mm (0.1098 inch). The full-radius geometry with a 0.79 mm corner radius and neutral rake angle supports stable chip control during grooving and profiling. Machining professionals and toolroom technicians select this insert for its KC850 grade performance in steel and cast iron applications.

This insert is suited for metric-dimensioned grooving applications on lathes running ferrous materials. The KC850 grade with CVD multilayer coating targets material grades C5 and C6, making it appropriate for steel turning and finishing passes where consistent groove geometry is required. It is a single-use, non-multi-purpose insert and is sold in minimum order quantities of 5 units, with individual package quantities of 1. The Top Notch series tooling system it belongs to is a widely used platform in production turning environments.

Installation Notes

This insert is installed and replaced by qualified machinists or toolroom technicians using the appropriate Top Notch series toolholder. Power down and lock out the machine spindle before seating or removing inserts. Use the correct insert-retention mechanism specified by the toolholder manufacturer and confirm proper seating before resuming cuts. Do not exceed the rated maximum depth of cut for this insert geometry.
