Abstract
A cutting element comprising a cylindrical substrate; a table bonded to the cylindrical substrate; at least one tooth with a reduced projected cutting area on a periphery of the table; and a plurality of undulating cutting ridges on a top of the table. The table can have a working surface and at least one lateral surface, and a chamfer formed therebetween. The working surface can be a non-planar working surface. For a given weight on the bit, the cutter will sink into the rock deeper which can lead to better stability and more effective rock removal.
