A rotary drag bit for drilling a subterranean formation includes a plurality of support elements affixed to the bit body, each forming at least a portion of a cutting element pocket. Each of a plurality of cutting elements has a substantially cylindrical body and is at least partially disposed within a cutter pocket. At least a portion of the substantially cylindrical body of each cutting element is directly secured to at least a portion of a substantially arcuate surface of the bit body. At least a portion of a substantially planar surface of each cutting element matingly engages at least a portion of a substantially planar surface of a support element.
