Versatile PVD-coated grade
Ti-enriched coating
– Thick Ti-enriched PVD coating for enhanced thermal shock resistance
– Reduced crater wear
High Ti-content nano-structured multilayer coating
The outer layer consists of a high Ti-content nano-structured multilayer made possible by Tungaloy’s latest coating technology. Its high hardness and nano structure provides the grade with a good balance of wear and fracture resistance, enhancing tool life and predictability.
Dedicated carbide substrate
Thanks to high thermal conductivity of the substrate, heat generated during machining is dissipated, efficiently reducing temperature on the cutting edge. This provides edge toughness, while reducing plastic deformation of the cutting edge. Ideal for continuous cuts.
AH6235 incorporates a tough substrate that provides process security during interrupted machining. This tough substrate provides the grade with added reliability during interrupted cuts.
Superior wear resistance
Enhanced hardness of outer layer
– Hard outer layer coating significantly reduces flank wear.
Strong adhesion of Al2O3 layers
– Tungaloy’s latest Al2O3 coating technology enhances the grade’s adhesion of coating, preventing edge chipping and coating delamination.
Thick coating
– 30% thicker than conventional grades.
– Provides superior wear resistance and long tool life.
