Kennametal 1113047 Grooving Insert NG2047 KC730 Carbide

Product Description

The KENNAMETAL 1113047 is a solid carbide grooving insert in the Top Notch series, designed for precision external grooving and parting operations on CNC lathes and turning centers. It carries a PVD-applied TiN coating for improved wear resistance and edge performance. The insert features a left-hand cutting orientation with a 1.19 mm cutting width and a maximum depth of cut of 1.27 mm. The corner radius measures 0.09 mm, and the rake is neutral, making it well-suited for consistent chip control in finish grooving applications. Installation and replacement are performed by qualified machinists or toolroom technicians.

This insert is intended for use in metal cutting applications involving grooving, profiling, and parting on turned components. It is compatible with toolholders in the Top Notch series that accept the NG insert style at the 2047 insert size. The KC730 grade is rated for material grades C2, C3, and C4, which corresponds to a broad range of cast iron and non-ferrous machining applications as well as general steel turning at moderate cutting parameters. The 55-degree included angle and 3-degree lead angle support controlled entry into narrow groove profiles.

Key Features

• 1.19 mm cutting width for precise narrow grooving operations
• Maximum depth of cut of 1.27 mm within a range of 0.00 to 2.00 mm
• Left-hand cutting orientation for dedicated left-hand toolholder setups
• 0.09 mm corner radius with neutral rake geometry for controlled chip formation
• KC730 grade rated for C2, C3, and C4 material groups

Compatibility

Designed for use with Top Notch series toolholders accepting NG-style inserts at the 2047 insert size. The KC730 grade is suitable for material grades C2, C3, and C4 cutting applications.

Installation Notes

Insert seating and clamping should be performed with the machine fully powered down and spindle locked. Use the appropriate Top Notch clamp and torque the clamping screw according to the toolholder manufacturer's specifications. Inspect the insert pocket for debris or damage before seating the insert. Handle carbide inserts with care to avoid chipping cutting edges prior to use.
