Superabrasive cutting assemblies including cutters of varying orientations and drill bits so equipped

A rotary drill bit for drilling subterranean formations, comprising:

• a bit body carrying at least one cutting assembly, comprising:
• at least one first cutting element comprising a first superabrasive table having a cutting face, a side and a first cutting edge defined at the side along a peripheral portion of the cutting face, the first superabrasive table being positioned with the cutting face oriented generally facing in an intended direction of bit rotation and suitable for engaging a formation with the first cutting edge;
• and
• a second cutting element positioned adjacent and rotationally behind the at least one first cutting element, the second cutting element comprising a second superabrasive table having a clearance face exhibiting a first lateral extent along a portion thereof, a side edge exhibiting a second lateral extent greater than the first lateral extent and in proximity to the first lateral extent, a rake face located between the clearance face and the side edge along a peripheral portion of the clearance face, and a second cutting edge defined between the clearance face and the rake face, the second cutting element being positioned with at least a portion of the rake face generally facing in the intended direction of bit rotation in an orientation suitable for engaging the formation with the second cutting edge.
