摘要： A self positioning cutter element and cutter pocket for use in a downhole tool having one or more cutting elements. The self positioning cutter element includes a substrate and a wear resistant layer coupled to the substrate. The cutter element includes a cutting surface, a coupling surface, and a longitudinal side surface forming the circumferential perimeter of the cutter element and extending from the cutting surface to the coupling surface. The cutter element has one or more indexes formed on at least a portion of the coupling surface. In some embodiments, the index also is formed on at least a portion of the longitudinal side surface. Hence, the coupling surface is not substantially planar. Additionally, at least a portion of the longitudinal side surface does not form a substantially uniform perimeter. The cutter pocket also is indexed to correspond and couple with the indexing of the cutter element.

摘要： An apparatus and method for manufacturing a downhole tool that reduces failures occurring along a bondline between a cemented matrix coupled around a blank. The cemented matrix material is formed from a powder and a binder material. The blank includes an internal blank component and a coating coupled around at least a portion of the surface of the internal blank component. The internal blank component includes a top portion and a bottom portion. The internal blank component is substantially cylindrically shaped and defines a channel extending through the top portion and the bottom portion. The coating is a metal in some exemplary embodiments. The coating reduces the migration of the binder material into the blank thereby allowing the control of intermetallic compounds thickness within the bondline.
摘要翻译：一种用于制造井下工具的装置和方法，其减少沿着围绕坯料耦合的胶结基体之间的粘合线发生的故障。粘结基质材料由粉末和粘合剂材料形成。坯料包括内部坯料组件和围绕内部坯件组件的表面的至少一部分耦合的涂层。内部空白部件包括顶部和底部。内部空白部件基本上为圆柱形并且限定了延伸穿过顶部部分和底部部分的通道。在一些示例性实施例中，涂层是金属。涂层减少了粘合剂材料向坯料的迁移，从而允许控制粘结层内的金属间化合物厚度。
