摘要： A cutting device includes, at least one stack of cutting elements attached to a cutter surface having, a first element and a second element attached to the cutter surface. A third element is attached to the first element and the second element. The three elements are sized and shaped such that prior to attachment to the cutter surface the three elements are restable in a stable manner on the cutter surface due to gravity alone. A plane-defined-surface defined by one of the two planes of a modified gilmoid of the third element positioned further from the cutter surface is oriented at an angle of about 35 to 55 degrees relative to the cutter surface.

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.

摘要： A cutting element includes a body having two planes, each of the two planes defining a plurality of edges, and a support extending from a first of the two planes. The support and the body are configured such that when at least one of the plurality of edges and the support are in contact with the planar surface, edges of the plurality of edges on a second of the two planes form cutting edges and the second of the two planes forms an acute angle with the planar surface. The second of the two planes of the cutting element has a recess formed therein sized and positioned to be receptive to a support of a second cutting element similar to the cutting element when the first of the two planes of the second cutting element is butted against the second of the two planes of the cutting element.
