[54] CUTTING ELEMENTS FOR DOWNHOLE CUTTING TOOLS
[57] Abstract: Cutting elements for downhole cutting tools comprise a top surface having a cutting surface ‎portion and a cutting profile disposed across the top surface. The cutting elements ‎comprise first and second longitudinal side surfaces and first and second lateral side ‎surfaces, each having a respective cross-section. The cutting profile can be disposed on the ‎cutting surface either asymmetrically or symmetrically. Asymmetrical disposition permits ‎two cutting elements to be arranged facing each other to cover a center point of a cutting ‎tool. The cutting edge of asymmetrical or symmetrically disposed cutting profiles can have ‎a shape that facilitates self-sharpening during cutting. ‎
