  • Patent number: 11136830
    Abstract: A downhole tool includes a cone with an outer surface, a cone axis, and a set on the outer surface thereof. The set includes first and second cutting elements. The first and second cutting elements have respective first and second grips that are different. Another downhole tool includes a body and a cone is connected to, and rotatable relative to, the body. Cutting elements on the cone are arranged in a set to vary in radial position relative to a cone axis, with a first position nearest to, and a last position farthest from, the cone axis. A first cutting element in the first position has a different cutting element geometry type than a second cutting element in the last position. First and second cutting elements may have the same cutting element geometry type and one or more cutting elements therebetween may have different cutting element geometry types.
