Product Description

The KENNAMETAL 1113829 is a solid carbide grooving insert in the Top Notch series, designed for precision grooving and parting operations on CNC lathes and turning centers. Grade KC850 carbide with a CVD-applied multilayer coating of TiC, TiCN, and TiN delivers thermal resistance and wear life across a wide range of workpiece materials. The insert provides a 4.78 mm cutting width and a maximum depth of cut of 6.35 mm, with a full-radius profile and a corner radius of 2.39 mm. Neutral rake geometry supports stable cutting action. This insert is suited for machinists and toolroom professionals working in production turning environments.

The 1113829 is intended for grooving, recessing, and cutoff applications on turning equipment that accepts Top Notch series toolholders. The NR insert style with a 4094 insert size fits compatible Top Notch insert seat size 4 holders. Material grade ratings of C5 and C6 make it applicable across medium to finish turning of steel, stainless, and similar materials. Right-hand cutting orientation applies to standard turning setups. Maximum depth of cut range runs from 5.00 mm to 10.00 mm, accommodating a variety of groove depth requirements in production runs.
