    摘要: 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.

    摘要: Downhole cutting tools such as blade mills comprise a body having a first end for connection with a rotating component of a drill string and a cutting end for rotation in unison with the body. The cutting end comprises at least two blades, each of the at least two blades comprising a front sidewall surface, a back sidewall surface, an inner end, an outer end, and at least one beveled portion disposed along the front sidewall surface toward the inner end of each of the at least two blades. At least one of the beveled portions comprise at least one cutting element disposed thereon that is disposed across a center point of the face of the cutting end to provide for cutting away an object disposed in a wellbore to occur across a center point of the cutting end.
