    摘要: In one aspect of the invention, a drilling assembly comprises a head located on a rotational axis of the assembly and comprises at least one head element. At least one blade extends distally from the head. A plurality of blade degradation elements are rotationally supported on the blade. Each degradation element comprises an attack angle that affects the penetration rate of each degradation element and a laterally offset angle that primarily affects the rotational rate of each degradation element within their holders. The drilling assembly comprises a central cutting region. The blade degradation elements within the central cutting region form an attack angle of 15 to 20 degrees with the rotational axis of the drilling assembly.

    摘要: In one aspect of the invention, an abrasion resistant nozzle has at least two sintered diamond bodies having flat, mating, exterior surfaces and a thickness, the surfaces being held against each other under compression. An enclosure is formed between the mating surfaces, at least one surface having a groove forming a portion of the enclosure and the other surface forming a remaining portion of the enclosure. The enclosure connects an entry and an exit formed in at least one side of at least one of the bodies.
