ABSTRACT:
A rotary drill bit for drilling subterranean wells comprises a plurality of radially adjacent cutting elements disposed in angularly spaced relationship on the end face of the drill bit. Behind each set of cutting elements, at least one stabilizing projection is formed on the drill bit. Such projection is of peripherally elongated configuration and is circumferentially aligned with one of the cutting elements so as to snugly enter and engage the side walls of the formation groove produced by the aligned cutting element, thus providing substantial resistance against lateral displacement or vibration of the drill bit.
