Kennametal 4034775 Grooving Insert KCU10 Solid Carbide

Product Description

The KENNAMETAL 4034775 is a solid carbide grooving insert designed for precision external and internal grooving operations on CNC lathes and turning centers. Built to the G insert style with a GMN chip breaker geometry, it delivers controlled chip evacuation during interrupted and continuous grooving cuts. The AlTiN coating is applied via a PVD process, providing excellent heat resistance and extended tool life in ferrous and hardened materials. With a cutting width of 3.05 mm (0.1201 inches) and a maximum depth of cut of 3.51 mm (0.1378 inches), this insert suits medium-depth groove profiles. It belongs to the KENNAMETAL Series A4 and is catalogued under manufacturer number A4G0305M03U04GMN.

This insert is intended for production turning and grooving applications in shops running steel, alloy steel, and similar workpiece materials classified under material grades C3 and C4. The neutral hand orientation makes it suitable for both right-hand and left-hand toolholders configured for that geometry. Its multi-use designation allows it to be used across grooving, parting, and profiling operations within its depth-of-cut range of 3.00 mm to 4.00 mm. Machinists and CNC setup technicians in metalworking shops are the primary installers and users of this insert.

Compatibility

Designed for use with KENNAMETAL Series A4 toolholders accepting G-style inserts with a 0305 insert size designation. Verify toolholder seat geometry and clamping style against the A4 series specification before installation. No additional specific model compatibility data was provided in the product input.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician with the machine in a powered-off and locked-out state per applicable machine safety procedures. Seat the insert fully in the toolholder pocket and tighten the clamping screw to the toolholder manufacturer's specified torque using the correct Torx or hex key. Inspect the insert seat and shim for chips or debris before seating to avoid micro-fracture of the carbide. Never exceed the published maximum depth of cut for this insert geometry.
