Tiger·tec Gold Inserts for Tough Steel Turning

Feb. 3, 2023
These gold inserts from Walter USA are designed for turning operations in all steel applications including low-carbon steels and alloy steels.

Tiger·tec Gold inserts are designed for turning operations in all steel applications including low carbon steels as well as various alloy steels. A patent-pending, highly textured MT-TiCN layer reduces flank face wear and increases toughness due to its multi-layered elastic structure. An additional highly textured Al2O3 layer increases the resistance to crater wear, while the gold-colored top layer helps improve wear detection. The final multi-stage proprietary post-treatment of the inserts ensures a rake face with reduced friction for easy chip evacuation and a high level of substrate toughness for resistance to chipping and notching.

These inserts are available in three CVD grades:

  1. WPP10G: highest wear resistance for continuous cuts primarily in steels (ISO P10) and secondarily in cast irons (ISO K20).
  2. WPP20G: universal grade capable of handling a wide range of applications including continuous cuts to moderately interrupted cuts in steels (ISO P20) and with secondary applications in cast irons (ISO K30).
  3. WPP30G: toughest grades for steels (ISO P30) and secondary applications in cast irons (ISO K20) respectively.

Being the toughest grade, WPP30G is also ideal for heavy interruptions, castings with scale, older unstable machine setups or any other applications that require a tough grade.


These indexable inserts are ideal for use in the automotive, energy, and general metalworking industries where the inserts can significantly help reduce the cost per component. Walter is offering Tiger·tec Gold indexable insert grades with its signature geometries starting with finishing (FP5), medium machining (MP3, MP5, MU5) all the way to roughing (RP7, HU5), etc. along with some other niche geometries for specialist troubleshooting purposes.
