  • Extrudate-producing ridged cutting element
    Patent number: 10830000
    Abstract: A cutting element for a drill bit includes a PCD cutting face having a ridge that extends away from the periphery towards the center of the cutting face, terminating in a curved, central most ridge end. The cutting face further includes a surrounding surface consisting of the entire cutting face except for the ridge. The surrounding surface is free of flats and includes two side regions and a ramp region therebetween. The surrounding surface is continuously curved along a curved path that extends from the first side region to the ramp region to the other side region. In profile views, the surrounding surface may be linear moving from the top surface of the ridge to the periphery at every location along the curved path.
