Kennametal 4176060 Grooving Insert NG3125 KCU10 Left Hand

Product Description

The KENNAMETAL 4176060 is a solid carbide grooving insert in the Top Notch series, designed for external grooving, parting, and profiling operations on CNC lathes and turning centers. The insert carries a KCU10 grade designation with a PVD-applied AlTiN coating, which provides thermal resistance and wear protection during interrupted cuts and general-purpose turning. It is configured for left-hand cutting, with a 3.18 mm (0.125 inch) cutting width and a maximum depth of cut of 3.81 mm (0.150 inch). The insert holds a corner radius of 0.19 mm (0.0075 inch) and a cutting height of 8.74 mm (0.344 inch). Metalworking machinists and CNC operators working in production environments are the primary installers.

This insert is suited for grooving and parting operations on a wide range of workpiece materials, consistent with C3 and C4 material grade designations, which correspond to cast iron and non-ferrous materials. The NG3125 insert style fits Top Notch compatible toolholders that accept clamp-style insert retention. The 55-degree included angle geometry supports profiling passes where clearance and reach are factors. It is applicable in both high-volume production and job-shop turning environments where repeatable groove width and depth control are required.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or CNC tooling technician with the machine in a full stop, spindle off, and energy-isolated state per applicable lockout/tagout procedures. Clamp screws should be seated with the appropriate Torx or hex key driver as specified by the toolholder manufacturer — do not use substitute tools that may strip the clamp. Verify insert seating and clamp engagement before resuming cutting operations. Dispose of used carbide inserts in accordance with local regulations for industrial cutting tool waste.
