A cutting element may include a substrate; and an ultrahard layer on the substrate, the ultrahard layer including a non-planar working surface that is surrounded by a peripheral edge having a varying height around a circumference of the cutting element, the working surface also having: a plurality of cutting crests extending from an elevated portion of the peripheral edge across at least a portion of the working surface; at least one valley between the plurality of cutting crests; and a canted surface extending laterally from each of the outer plurality of cutting crests towards a depressed portion of the peripheral edge, a height between the depressed portion and the elevated portion being greater than a height between the elevated portion and the valley.

Multiple ridge cutting element

A downhole cutting tool includes a body having a central axis extending therethrough, a plurality of blades extending outwardly from the body and converging towards a central region around the central axis, and at least one cutting element having a longitudinal axis, a non-cylindrical substrate, and an ultra-hard material body on the non-cylindrical substrate, the ultra-hard material body having a side surface extending around a cutting face and defining a cross-sectional shape of the ultra-hard material body, and the side surface comprising an edge having an inner angle of less than 180 degrees.

Fixed cutter bits and other downhole tools having non-planar cutting elements thereon

A fixed cutter drill bit may include a bit body having a bit centerline and a plurality of blades that extend radially from the bit body and are separated by a plurality of flow courses therebetween. Each of the plurality of blades is spaced a radial distance from the bit centerline to define a core-forming region. A plurality of cutting elements is disposed on the plurality of blades. The plurality of cutting elements comprises at least two coring cutting elements that are disposed on the plurality of blades and the at least two coring cutting elements are the radially innermost cutting elements on the plurality of blades.
