Kennametal 4034821 Grooving Insert KCU10 6mm Carbide

Product Description

The KENNAMETAL 4034821 is a solid carbide grooving insert designed for precision external grooving and parting operations on CNC lathes and turning centers. Manufactured to the A4 series standard, this insert carries the R0600GMP designation with a KCU10 grade and a PVD-applied AlTiN coating for extended tool life in demanding cutting environments. The neutral hand orientation suits a wide range of toolholder setups. With a 6 mm cutting width and a maximum depth of cut of 4.88 mm, this insert is suited for machinists and toolroom technicians working to tight dimensional tolerances on ferrous and non-ferrous workpieces.

This insert is intended for use in production turning and toolroom applications where consistent groove geometry and surface finish are required. The full-radius profile, with a corner radius of 3.00 mm, makes it appropriate for full-radius grooving profiles as well as finishing passes in recessing operations. It is typically installed by CNC machinists and toolroom technicians in industrial manufacturing environments where repeatable grooving performance is critical.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician following the toolholder manufacturer's clamping torque specifications. Ensure the machine spindle is fully stopped and the turret is indexed to a safe position before replacing inserts. Use the correct insert seating tool or torx key as specified by the toolholder manufacturer to avoid seat damage. Inspect the insert pocket and clamping screw for wear or debris before seating the new insert.
