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. The cap can be used with the belted mold assembly or with a casting assembly known in the prior art. | 09-01-2011 |
20110209922 | CASING END TOOL - 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. | 09-01-2011 |
20140090901 | MACHINED HIGH ANGLE NOZZLE SOCKETS FOR STEEL BODY BITS - An apparatus that includes one or more machined high-angle sockets and method for fabricating such sockets. The apparatus includes a body, one or more blades extending outwardly from the body, and one or more high-angle nozzles machined into a portion of the blade. The body includes a bit face at one end and a plenum formed therein communicably coupled to an opening formed at an opposing end. Each blade includes a leading section, a trailing section, a face section extending from one end of the leading section to an end of the trailing section, and an inner section extending from an opposing end of the leading section to an opposing end of the trailing section. Each nozzle includes a nozzle socket cavity and a second hole intersecting with the nozzle socket cavity and extending to the plenum, which collectively form a passage extending from the plenum to the bit face. | 04-03-2014 |
20150226010 | MILL-DRILL CUTTER AND DRILL BIT - A mill-drill cutter for an earth boring bit includes a cutting structure secured to a substrate. The cutting structure has a drilling edge, and the substrate has a milling edge. The substrate is configured to be received in a cutter pocket of the earth boring bit. The drilling edge of the cutting structure is disposed radially internal to the milling edge of the substrate. | 08-13-2015 |
