Kennametal 1113579 Grooving Insert NG3142 K68 Carbide

Product Description

The KENNAMETAL 1113579 is a solid carbide grooving insert designed for precision external grooving operations on CNC lathes and turning centers. Manufactured in the NG3142 style with a K68 grade uncoated carbide substrate, this insert delivers a cutting width of 3.61 mm (0.1421 inches) and a maximum depth of cut of 3.81 mm (0.15 inches). The bright, uncoated finish makes it well suited for applications where coating adhesion or built-up edge is a concern. With a neutral rake geometry and a 0.32 mm corner radius, the insert provides controlled chip formation during grooving passes. It is part of the Top Notch series and is intended for use by machinists and CNC operators working in production and job-shop environments.

This insert is appropriate for grooving applications on ferrous and non-ferrous workpiece materials where a C3 material grade carbide is specified. The right-hand cutting orientation suits standard lathe setups with conventional tool holding. The Top Notch series toolholder system is the intended platform for this insert. Typical applications include OD grooving, undercutting, and recessing operations on turned components. The included angle of 55 degrees and lead angle of 3 degrees define the insert geometry for these cutting scenarios. Machinists running high-volume turning operations will find this insert consistent with OEM replacement requirements for Top Notch compatible toolholders.

Compatibility

Designed for use with Top Notch series toolholders accepting the NG3142 insert style. Verify toolholder seat style and insert size designation before installation.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist following the toolholder manufacturer's instructions. Power down and lock out the machine before changing inserts. Ensure the insert pocket is clean and free of debris before seating to prevent improper clamping and premature insert failure. Follow shop-specific tooling procedure guidelines and applicable OSHA machine safety requirements when handling carbide inserts.
