Kennametal 1113045 Grooving Insert NG2031 KC730 Solid Carbide

Product Description

The KENNAMETAL 1113045 is a solid carbide grooving insert in the Top Notch series, designed for precision grooving and parting operations on CNC lathes and turning centers. Manufactured to the NG2031 insert style, it carries a KC730 grade designation and a Physical Vapor Deposition (PVD) titanium nitride (TiN) coating that improves wear resistance and extends tool life. The insert is configured for left-hand cutting with a neutral rake geometry, a 0.79 mm cutting width, and a maximum depth of cut of 1.27 mm. It is suited for machinists and tooling engineers running tight-tolerance grooves in steel, cast iron, and non-ferrous alloys classified under material grades C2, C3, and C4.

This insert is appropriate for use in production turning environments where consistent groove geometry and finish quality are required. The Top Notch series is a well-established tooling platform commonly found in job shops and production cells handling medium to light grooving cuts. With a 55-degree included angle and a 0.09 mm corner radius, the 1113045 is suited for fine grooves and undercuts where clearance and precise dimensional control are priorities. Installation requires a compatible Top Notch series toolholder. Sold individually, with a minimum order quantity of 5 units.

Key Features

• 55-degree included angle with a 3-degree lead angle
• Compatible with material grades C2, C3, and C4 workpiece materials

Compatibility

Designed for use in compatible Top Notch series toolholders. Material grade compatibility includes C2, C3, and C4 classifications. Verify toolholder seat geometry and clamping style against the NG insert style before installation.

Installation Notes

This insert is installed and serviced by qualified machinists or tooling technicians. Power down and lock out the machine spindle before replacing inserts. Use the appropriate insert seating tool or torx key specified by the toolholder manufacturer to secure the clamping screw — do not overtighten by hand or with non-specified tooling. Inspect the toolholder pocket for wear or damage before seating a new insert.
