Abstract
A cutting element includes a substrate and a cutting table secure to the substrate. The cutting table includes a first surface, a cutting surface, a first transition surface, and a second transition surface. The cutting surface at least substantially surrounds an outer boundary of the first surface and is angled relative to a longitudinal centerline of the cutting table. The first and second transition surfaces are between the cutting surface and an outer lateral edge of the cutting table. The first and second transition surfaces are oriented at a first angle and a second different angle, respectively, relative to the longitudinal centerline of the cutting table. An earth-boring tool and method of forming an earth-boring tool are also described.
