Kennametal 1113030 NG2047 KC730 Grooving Insert Top Notch

Product Description

The KENNAMETAL 1113030 is a solid carbide grooving insert in the Top Notch series, designed for precision grooving and cutoff operations on CNC lathes and turning centers. It carries the KC730 manufacturer grade with a PVD-applied TiN finish, delivering controlled wear resistance in a right-hand cutting orientation. The insert features a 1.19 mm cutting width and a maximum depth of cut of 1.27 mm, making it well-suited for narrow-groove work requiring tight dimensional control. Machinists and tooling technicians install this insert into compatible Top Notch toolholders as a direct indexable unit.

This insert is used in precision turning applications targeting materials in the C2, C3, and C4 material grade classifications, which span a range of cast irons and non-ferrous alloys. It is suited for light to moderate grooving passes in both production and job-shop environments where consistent groove width and a clean finish are required. The neutral rake geometry and 3-degree lead angle support stable chip formation during interrupted or continuous grooving cuts. A corner radius of 0.09 mm provides a controlled edge transition without a full radius profile.

Key Features

• Solid carbide construction with PVD TiN coating for extended wear life
• 1.19 mm cutting width for narrow-groove precision applications
• Maximum depth of cut: 1.27 mm (range up to 2.00 mm per series spec)
• KC730 grade optimized for C2, C3, and C4 workpiece materials
• Right-hand cutting orientation with neutral rake and 3-degree lead angle
• Corner radius of 0.09 mm for controlled edge geometry without full radius

Compatibility

Designed for use in Top Notch series toolholders accepting NG-style inserts, size 2047. Compatible with systems specifying MSC/Manufacturer Number NG2047R/L.

Installation Notes

This insert is installed and indexed by a qualified machinist or tooling technician following the toolholder manufacturer's clamping procedure. Power down and lock out the machine spindle before seating or replacing the insert. Ensure the insert pocket is clean and free of chips or debris before installation to maintain proper seating and dimensional accuracy. Do not exceed the rated maximum depth of cut for the insert size.
