Kennametal 4114343 Grooving Insert KCU25 Carbide Altin

Product Description

The KENNAMETAL 4114343 is a solid carbide grooving insert designed for precision external grooving and parting operations on CNC turning centers and lathes. Manufactured in the A4 series and graded KCU25, this insert features a Physical Vapor Deposition (PVD) AlTiN coating that improves wear resistance and tool life in interrupted cuts and hard-material applications. The neutral hand orientation suits a broad range of standard grooving toolholders. With a cutting width of 0.0787 inches and a maximum depth of cut of 0.067 inches, it is suited for fine, controlled groove profiles where dimensional accuracy is critical. The GMP chip breaker geometry promotes effective chip control at the cutting edge.

This insert is intended for use in metal-cutting applications where groove width consistency and surface finish are priorities. The full-radius corner profile, measuring 0.0394 inches, supports smooth groove floor geometry. Typical installation scenarios include production turning operations on steel, stainless, and difficult-to-machine alloys where PVD-coated carbide tooling is specified. Machinists and CNC operators in job shops, production facilities, and tool rooms are the primary users of this insert style.

Installation Notes

Insert installation and replacement should be performed by a qualified machinist or CNC operator with the machine in a full stop, locked-out state per shop lockout/tagout procedures. Use the appropriate torx or hex key to secure the insert clamp to the manufacturer-specified seating torque as referenced in the toolholder documentation. Inspect the insert pocket and clamping mechanism for debris or wear before seating the new insert. Do not exceed the maximum depth of cut specification during programming or setup.
