Abstract
Cutting elements for earth-boring tools may include a rotationally leading end positioned and configured to engage with, and remove, a material of an earth formation. A transition region may extend from proximate to a periphery of the cutting element radially inward and axially toward the rotationally leading end. The transition region may include first faceted surfaces, each first faceted surface extending at a first angle relative to a central geometric axis of the cutting element. The transition region may also include second faceted surfaces, each second faceted surface extending at a second, different angle relative to the central geometric axis of the cutting element. The first faceted surfaces and the second faceted surfaces may intersect one another at edges around a periphery of the transition region.
