Abstract
The present disclosure relates to cutting tool edges that include on a rake face a superabrasive layer and a HPHT sintered or HPHT bonded cap layer. The cap layer improves adhesion between the superabrasive layer and an optional coating system for the cutting insert and acts as a thick anti-friction layer and/or a thermal barrier coating.
