Kennametal 4034773 Grooving Insert G0305GMN KCU10 Series A4

Product Description

The KENNAMETAL 4034773 is a solid carbide grooving insert designed for precision external and internal grooving operations on CNC lathes and turning centers. Manufactured to the G0305GMN geometry with a KCU10 grade, this insert features a PVD-applied AlTiN coating that improves wear resistance and thermal stability during interrupted or continuous cuts. The neutral hand orientation makes it compatible with both left- and right-hand toolholders. With a 3.05 mm cutting width and a maximum depth of cut of 3.51 mm, it is suited for tight-tolerance groove profiles in production turning environments. Machinists and CNC operators working in job shops or high-volume facilities are the primary installers.

This insert is used in metalcutting applications where controlled groove width and depth are required. The A4 series geometry with the GMN chip breaker is engineered for consistent chip control across a range of workpiece materials, including steels and alloys. Its 90-degree included angle and 0.20 mm corner radius support repeatable groove profiles with minimal burring. The multi-use designation means the insert can be indexed or repositioned for extended service life per edge.

Installation Notes

Installation is performed by qualified CNC machinists or tool-crib technicians. Ensure the machine spindle is fully stopped and the turret is in a safe index position before seating or replacing the insert. Use the appropriate torx or hex key specified by the toolholder manufacturer to achieve proper clamping torque. Inspect the insert pocket for chips or debris before seating to prevent micro-fracture from improper seating.
