    摘要： A drill bit for drilling a borehole includes a cutter element comprising a base portion. In addition, the cutter element comprises a cutting portion extending from the base portion and terminating in an elongate crest extending between a first crest end and a second crest end, and having an intermediate portion therebetween. The first crest end has a width W1 and the second end has a width W2 that is greater than the width W1. Still further, the intermediate portion of the crest has a width W3 that is less than the width W2 and less than or equal to the width W1.

    摘要： A drill bit for cutting a borehole comprises a bit body including a bit axis. In addition, the drill bit comprises a rolling cone cutter mounted on the bit body. Further, the drill bit comprises a cutter element having a base portion with a diameter and a cutting portion extending therefrom. The cutting portion comprising a first pair of flanking surfaces that taper towards one another to form a first elongate chisel crest, and a second pair of flanking surfaces that taper towards one another to form a second elongate chisel crest that intersects the first elongate chisel crest in top view. The first crest tangent angle at 10% of the diameter measured radially from the central axis on the first elongate chisel crest in profile view is greater than 75° and less than or equal to 90°.
