Kennametal 1113059 NG3189 KC730 Carbide Grooving Insert

Product Description

The KENNAMETAL 1113059 is a solid carbide grooving insert designed for precision external grooving and parting operations on CNC lathes and turning centers. Part of the Top Notch series, it carries a KC730 grade designation and a Physical Vapor Deposition (PVD) TiN coating that provides wear resistance and extended tool life. The insert delivers a cutting width of 4.8 mm (0.189 inches) and a maximum depth of cut of 3.81 mm (0.150 inches). The right-hand orientation and neutral rake geometry make it suitable for consistent, controlled material removal on a range of workpiece materials. This insert is sold individually but requires a minimum order of 5 units.

This insert is intended for use in turning and grooving applications across metalworking environments, including production machining shops and job shops running ferrous and non-ferrous materials. The KC730 grade with TiN PVD coating is suited for material grades C2, C3, and C4, covering a broad range of cast irons and steels. It fits Top Notch series compatible toolholders and is appropriate for machinists and CNC operators handling light to moderate grooving depths. The 55-degree included angle and 3-degree lead angle contribute to precise groove geometry on finished parts.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Before indexing or replacing inserts, ensure the machine spindle is fully stopped and all energy sources are locked out per shop safety procedures. Seat the insert fully and evenly in the toolholder pocket and tighten the clamping screw to the toolholder manufacturer's specified torque. Verify insert orientation and overhang before resuming cutting operations.
