  • Drill bit (well) Wikipedia

    Rolling cutter bits drill largely by fracturing or crushing the formation with "tooth"shaped cutting elements on two or more coneshaped elements that roll across the face of the borehole as the bit is rotated Fixed cutter bits employ a set of blades with very hard cutting elements, most commonly natural or synthetic diamond, to remove material by scraping or grinding action as the bit is
