KCU25B Inserts with Multi-Layer KENGold™ PVD Coating

The KCU25B insert is an upgraded version of Kennametal’s existing KCU25 insert, featuring a newly designed multi-layer KENGold™ PVD coating.

This innovation enables effortless machining of various materials while ensuring consistent cutting performance.

The nano-composite coating enhances adhesion, providing superior wear resistance and reducing cutting-edge chipping. Upgrade your projects with improved material versatility and shorter machining times for steels, stainless steel, cast irons, high-temperature alloys, and non-ferrous materials.


KCU25B Availability


KCU25B is available in various insert shapes and for multiple applications:
  • A2: Parting
  • A4: Grooving, turning, and parting processes
  • K-Lock: R-shapes
  • Fix-Perfect: C-shapes, D-shapes, E-shapes
  • Beyond Evolution: Grooving, turning, and parting processes
  • Kenloc: C-shapes, D-shapes, S-shapes, T-shapes, V-shapes, W-shapes
  • Top Notch: D-shapes, V-shapes, K-shapes
  • Screw-on: C-shapes, D-shapes, R-shapes, S-shapes, T-shapes, V-shapes, W-shapes


In-Depth Look at KENGold™ PVD Coating Technology

This advanced multi-layer coating technology consists of three distinct layers, each with unique protective properties:
  • Top layer (TiSiN): Gold-colored for easy wear detection.
  • Second layer (AlTiSiN): Super-hard nanostructured intermediate layer providing exceptional wear resistance.
  • Third layer (AlTiN): Low-stress base layer for excellent delamination resistance.

The multi-layer coating applied to carbide inserts enhances thermal deformation resistance and delivers outstanding cutting edge wear protection.
