Kennametal 4176044 Grooving Insert NG3072 KCU10 Solid Carbide

Product Description

The KENNAMETAL 4176044 is a solid carbide grooving insert in the Top Notch series, designed for precision grooving and parting operations on CNC lathes and turning centers. It carries the KCU10 manufacturer grade with a PVD-applied AlTiN coating, delivering heat and wear resistance in demanding interrupted-cut and continuous-cut environments. The insert features a 1.83 mm (0.0720 inch) cutting width and a maximum depth of cut of 2.39 mm (0.0941 inch). The double-ended geometry extends usable tool life per insert. This insert is installed by machining professionals and tool room technicians in production turning and job-shop environments.

This insert is suited for grooving, recessing, and parting on ferrous and non-ferrous workpieces where tight dimensional control is required. The NG insert style fits Top Notch compatible toolholders with an insert seat size of 3. The right-hand cutting orientation positions it for standard OD grooving operations on conventional and gang-style turning setups. Material grades C3 and C4 make it appropriate for a range of steel and cast iron applications at moderate-to-higher surface speeds.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before seating or removing inserts. Ensure the toolholder pocket and clamping surfaces are clean and free of chips before installation to maintain proper insert seating. Follow the toolholder manufacturer's clamping torque specifications and do not exceed the maximum depth of cut rating for the insert.
