Abstract: A down hole tool casting assembly, a gauge ring, and a method for preparing the gauge ring for use within the assembly. The gauge ring includes a bit diameter mold and one or more junk slot displacements extending inwardly from the interior surface of the bit diameter mold. The junk slot displacement includes a first end, a second end, and a junk slot displacement face extending from the first end to the second end. At least one groove is formed within the interior surface of the gauge ring, which alleviates stresses formed within the casting during the casting process. According to some embodiments, at least one groove is formed within the junk slot displacement face. According to some embodiments, at least one groove is formed within the interior surface of the bit diameter mold. Optionally, a pressure absorbing material is inserted into one or more grooves.

Abstract: 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.

Abstract translation: 一种用于具有一个或多个切割元件的井下工具中的自定位刀具元件和刀具槽。 自定位刀具元件包括衬底和耦合到衬底的耐磨层。 切割元件包括切割表面，联接表面和形成切割元件周向周边并从切割表面延伸到联接表面的纵向侧表面。 切割器元件具有形成在联接表面的至少一部分上的一个或多个索引。 在一些实施例中，索引也形成在纵向侧表面的至少一部分上。 因此，联接表面基本上不是平面的。 此外，纵向侧表面的至少一部分不形成基本均匀的周长。 切割器凹坑也被索引以与切割器元件的分度对应并耦合。
