Abstract
A cutting element comprises a supporting substrate, a cutting table comprising a hard material attached to the supporting substrate, and a fluid flow pathway extending through the supporting substrate and the cutting table. The fluid flow pathway is configured to direct fluid delivered to an outermost boundary of the supporting substrate through internal regions of the supporting substrate and the cutting table. A method of forming a cutting element and an earth-boring tool are also described.
