Kennametal 1113518 Grooving Insert NR2031 K68 Carbide

Product Description

The KENNAMETAL 1113518 is a solid carbide grooving insert designed for precision turning and grooving operations on CNC lathes and turning centers. Part of the Top Notch series, this uncoated bright-finish insert features a right-hand cutting orientation and a 1.58 mm cutting width with a maximum depth of cut of 2.79 mm. The K68 grade carbide provides wear resistance suited for non-ferrous and cast iron applications. With a full radius geometry and a neutral rake angle, this insert delivers consistent chip control and surface finish in groove-turning applications. It is installed and replaced by machinists and CNC turning technicians.

This insert is intended for grooving and turning operations where metric tooling is specified. The NR2031 insert style fits Top Notch compatible toolholders designed for that insert size. With a corner radius of 0.79 mm and an included angle of 55 degrees, it suits fine grooving work in materials that align with the C3 material grade classification. Typical applications include external grooving on bar stock, tubing, and turned components in job shop and production turning environments.

Key Features

• Solid carbide K68 grade construction for wear resistance in non-ferrous and cast iron cutting
• 1.58 mm cutting width with a maximum depth of cut of 2.79 mm
• Full radius geometry with a 0.79 mm corner radius for consistent groove profiles
• Bright uncoated finish suited for applications where coatings are not required
• Neutral rake angle supports stable cutting forces and predictable tool life
• Right-hand cutting orientation for standard CNC turning setups

Compatibility

Designed for use with Top Notch series compatible toolholders accepting the NR2031 insert size. Consult the toolholder manufacturer specifications to confirm insert seat compatibility before installation.

Installation Notes

This insert is installed by machinists or CNC turning technicians using the appropriate torque wrench and insert clamp hardware specified by the toolholder manufacturer. Power down and lock out the machine spindle before changing inserts. Do not use damaged or chipped inserts, as this can affect dimensional accuracy and risk tool ejection. Dispose of worn carbide inserts in accordance with local regulations for industrial cutting tool waste.
