Product Description

The KENNAMETAL 1112965 is a solid carbide grooving insert in the Top Notch series, designed for external grooving and parting operations on CNC lathes and turning centers. It carries the KC730 grade with a PVD-applied TiN coating, which provides wear resistance and extended tool life on a range of workpiece materials. The insert features a right-hand cutting orientation, a 1.58 mm cutting width, a maximum depth of cut of 2.39 mm, and a full radius corner geometry with a 0.79 mm corner radius. Machinists and toolroom professionals install this insert into compatible Top Notch toolholders for precision groove profiling on ferrous and non-ferrous components.

This insert is suited for grooving applications in both production and job-shop environments. It is appropriate for turning operations on steel, cast iron, and non-ferrous materials classified under material grades C2, C3, and C4. The neutral rake geometry and full radius profile make it a practical choice for generating clean, consistent groove forms on small-diameter workpieces. It is sold individually with a minimum order quantity of 5 units per transaction.
