Kennametal 4176067 Grooving Insert NG3156K KCU10 Carbide

Product Description

The KENNAMETAL 4176067 is a solid carbide grooving insert designed for precision external grooving operations on CNC lathes and turning centers. This right-hand insert carries the KCU10 manufacturer grade with a PVD-applied AlTiN coating, delivering heat and wear resistance suited to a broad range of workpiece materials. The insert style is NG with a 3.96 mm cutting width and a maximum depth of cut of 3.81 mm. The K chip breaker geometry promotes controlled chip evacuation during interrupted and continuous grooving passes. It belongs to the Top Notch series and is held in place by a clamp-style toolholder.

This insert is intended for use in production turning environments where grooving, parting, and profiling operations are performed on ferrous and non-ferrous materials. The AlTiN coating and C3/C4 material grade designation make it appropriate for medium to hard cutting conditions. Machinists and CNC operators working in job shop and production settings will find this insert suited to both roughing and finishing groove passes within its rated depth range of 3.00 mm to 4.00 mm. It installs into compatible Top Notch series clamp-style grooving toolholders.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or removing the insert. Ensure the toolholder pocket and clamp seat are clean and free of chips before installing to avoid seating errors that can cause premature edge failure. Follow the toolholder manufacturer torque specifications for the clamping screw — do not overtighten.
