1. A cemented carbide composition, comprising:
a hard phase comprising tungsten carbide (WC) as a first hard phase component and second hard phase components comprising tantalum carbide (TaC) present in an amount of from 3.3 wt. % to 9 wt. % based on a total weight of the cemented carbide composition and niobium carbide (NbC) present in an amount of from 18 wt. % to 20 wt. % based on a total weight of the cemented carbide composition; and
a binder phase comprising at least one binder selected from the group consisting of cobalt (Co), nickel (Ni), and a mixture thereof.
