Kennametal 4176049 Grooving Insert NG3078K KCU10 Carbide

Product Description

The KENNAMETAL 4176049 is a solid carbide grooving insert in the Top Notch series, designed for external grooving and turning operations on CNC lathes and turning centers. It carries the NG3078K insert designation with a KCU10 manufacturer grade and an AlTiN finish applied via PVD coating. The cutting width is 1.98 mm and the maximum depth of cut is 2.39 mm, placing it in the 2.00 to 3.00 mm depth-of-cut range. This insert is configured for right-hand cutting. It is seated and held in place by a clamp-style insert holding method. Metalworking machinists and CNC operators working in production turning environments are the primary installers of this tooling.

This insert is suited for grooving, parting, and profiling applications on lathes and turning centers where precise groove widths and controlled depth of cut are required. The K chip breaker geometry and AlTiN PVD coating make it appropriate for use on a range of workpiece materials including steels and cast irons in the C3 and C4 material grade classifications. It is a single-use, non-multi-use insert intended for repeatable tooling changeouts in production environments.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician with the machine powered down and the spindle locked before changing inserts. Use the appropriate torx or clamping key specified for the toolholder to secure the insert without over-torquing the clamp screw. Inspect the insert seat and clamp for wear or debris before seating the new insert. Handle carbide inserts with care to avoid chipping the cutting edge prior to use.
