Kennametal 1113062 Grooving Insert NG3072 KC730 Carbide

Product Description

The KENNAMETAL 1113062 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 features a KC730 grade substrate with a PVD-applied TiN coating for extended tool life in a range of workpiece materials. The insert carries a right-hand orientation and a neutral rake geometry, with a cutting width of 1.83 mm and a maximum depth of cut of 2.39 mm. The 55-degree included angle and 0.19 mm corner radius make it well suited to controlled, repeatable groove profiles in production turning environments. Machinists and CNC operators install this insert as a direct indexable component in compatible Top Notch toolholders.

This insert is intended for use in metalworking operations requiring consistent groove geometry on turned components. It is appropriate for machining materials classified under C2, C3, and C4 material grades, covering a broad range of steels and cast irons. The NG3072 insert size fits within the Top Notch toolholder system, making it a standard choice for shops running high-volume grooving cycles on horizontal or vertical turning machines. Its PVD TiN coating supports performance in both dry and flood-coolant cutting conditions.

Key Features

• Solid carbide construction with KC730 grade for wear resistance and edge stability
• PVD TiN coating applied for improved surface hardness and reduced built-up edge
• 1.83 mm cutting width with a maximum depth of cut of 2.39 mm
• Neutral rake geometry with a 0.19 mm corner radius for controlled chip formation
• Right-hand insert orientation for standard external grooving setups
• Part of the Top Notch series for compatibility with the corresponding toolholder platform

Compatibility

Designed for use with Top Notch series toolholders accepting the NG3072 insert size. Compatible with workpiece materials in C2, C3, and C4 material grades. Maximum depth of cut range is 2.00 mm to 3.00 mm.

Installation Notes

This insert is installed and indexed by a qualified machinist or CNC operator following the toolholder manufacturer's clamping procedure. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench and clamping hardware specified for the Top Notch toolholder to avoid insert movement or seating damage. Do not exceed the rated maximum depth of cut for the insert size.
