Patent number: 8915166Abstract: A bit mold is milled using a turning stage which forms a base mold component and a base gagering component. Next, a blade milling stage is performed in which the base mold component and base gagering component are milled to define integral junkslot formers separated by blade regions. Lastly, a pocket milling stage is performed in which the blade regions and integral junkslot formers of the base mold component are milled to define a plurality of cutter pockets in primary and perhaps secondary rows. Each cutter pocket includes a seat portion and a face portion. The milling of the pocket milling stage provides, at one or more of the cutter pockets, a facet. This facet is provided in an area about the junkslot former associated with the face portion of the cutter pocket, the face portion having, due to the presence of the facet, a surface for matching a cutter core displacement end surface without voids of a size which would require the use of fill material.Type: GrantFiled: July 25, 2008Date of Patent: December 23, 2014Assignee: Varel International Ind., L.P.Inventors: Scott Buteaud, Cary Maurstad

Patent number: 8251122Abstract: 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.Type: GrantFiled: November 16, 2010Date of Patent: August 28, 2012Assignee: Varel Europe S.A.S.Inventors: Gilles Gallego, Anthony Salliou, Scott Buteaud, Michael R.

Patent number: 8079402Abstract: An apparatus and method for manufacturing a down hole tool that reduces manufacturing costs and enhances the tool's performance. A belted mold assembly includes a casting assembly, a belt assembly, and a mid-belt. The belted mold assembly is used to fabricate a casting that allows for a larger diameter blank to be used which displaces the more expensive casting material and for using a smaller outer diameter thin-walled mold. The casting assembly is disposed within the belt assembly and the mid-belt is loaded in the volume created between the casting assembly's outer surface and the belt assembly's inner surface. The mid-belt provides a bracing for the casting assembly during the casting process. Optionally, a cap can be disposed on top of the blank for preventing metallurgical bonds from forming between the binder material and the upper portion of the blank. This allows for the excess binder material to remain high in purity so that it can be reprocessed.Type: GrantFiled: May 10, 2011Date of Patent: December 20, 2011Assignee: Varel Europe S.A.S.Inventors: Michael R. Reese, Gilles Gallego, Scott Buteaud, Alan K. Harrell, Steven W. Drews

Publication number: 20110209922Abstract: A casing end tool has a mandrel and a body that is defined by a wall having an outer surface and an inner surface opposite of the outer surface. The body is fabricated from crystalline tungsten powder and a binder material. The inner surface includes a set of raised bosses or land structures. The body includes a plurality of blades on the outer surface. Each blade has a plurality of cutters. Blade channels and cutter channels on the blades enhance fragmentation of the body during drill out of the casing end tool.Type: ApplicationFiled: April 27, 2011Publication date: September 1, 2011Applicant: Varel InternationalInventors: William W.
