Kennametal 4034718 Grooving Insert G0205GMN KCU10 Carbide

Product Description

The KENNAMETAL 4034718 is a solid carbide grooving insert designed for precision external and internal grooving operations on CNC lathes and turning centers. Manufactured in the A4 series with a G0205GMN chip breaker geometry, this insert delivers a 2.05 mm cutting width and a maximum depth of cut of 2.00 mm. The physical vapor deposition (PVD) AlTiN coating provides thermal resistance and wear protection at elevated cutting temperatures. With a neutral hand orientation and a 0.20 mm corner radius, it is suited for tight-tolerance groove profiles in steel and harder workpiece materials. Machinists and CNC turning specialists are the primary installers of this insert type.

This insert is intended for grooving applications on metal workpieces where controlled chip formation and dimensional accuracy are required. The GMN chip breaker geometry supports efficient chip evacuation in shallow grooving passes within the 2.00 mm to 3.00 mm maximum depth of cut range. The 90-degree included angle and multi-use capability make it applicable across a range of groove widths and profiles in production turning environments. It is sized for use in compatible A4 series Kennametal toolholders that accept the G0205 insert form factor.

Installation Notes

This insert is installed and replaced by qualified machinists or CNC tooling technicians. Power down and lock out the machine before changing inserts. Use the appropriate torque wrench and insert clamp hardware specified by the toolholder manufacturer — do not overtighten or substitute fasteners. Inspect the insert pocket and seating surface for chips or debris before seating the new insert to ensure proper contact and runout control.
