Abstract

A drill bit for drilling a wellbore penetrating a subterranean formation is disclosed. The drill bit includes a bit body having a surface about a working end thereof, ribs extending from the surface of the bit body with channels defined therebetween, cutting elements positionable on the ribs to cuttingly engage the subterranean formation and release cuttings therefrom, and an anti- balling composition. The anti-balling composition includes a hardphase having a chemical potential that is more electronegative than the surface. The anti-balling composition is disposed on a surface of the bit body whereby the cuttings from the wellbore are prevented from collecting on the bit body.
