Abstract

An earth boring drill bit comprising a milled cutter having rows of teeth hardfacing guides on the cutter. Hardfacing is applied between adjacent teeth hardfacing guides to form a cutting element. The hardfacing may extend past the crest of the teeth hardfacing guides or end along the teeth hardfacing guides flanks.
