Cutting elements configured to reduce impact damage and related tools and methods

摘要

Cutting elements for earth-boring tools may include a substrate and a polycrystalline, superabrasive material secured to an end of the substrate. The polycrystalline superabrasive material may include a first transition surface extending in a direction oblique to a central axis of the substrate, a second transition surface extending in a second direction oblique to the central axis, the second direction being different from the first direction, and a curved, stress-reduction feature located on the second transition surface.
