    摘要： A hybrid drill bit having at least two rolling cutters, each rotatable around an axis of rotation, at least one of the rolling cutters having a high pin angle, and at least one fixed blade. The pin angle can encompass pin angles above 39 degrees to less than 393 degrees. The drill bit can allow the rolling cutters to engage a shoulder portion and/or gage portion of the bit profile and assist the fixed blade(s) in these areas. The at least two rolling cutters can be disposed at different pin angles.

    摘要： A shank configuration for rotary drill bits, is disclosed for positioning of the shank in relation to the bit body. A tapered surface or feature of the shank may be configured and sized to matingly engage a complementarily shaped surface or feature of the drill bit body and thereby become centered or positioned in relation thereto. A deformable element may be disposed between the shank and bit body. Also, the shank may comprise a material having a carbon equivalent of less than about 0.35%. A multi-pass weld procedure may be employed to affix the shank and bit body to one another wherein welds may be formed so that one weld originates at a circumferential position that differs from the origination circumferential position of its immediately preceding weld by at least about 90%. Further, a stress state may be developed within the multi-pass weld. A method of manufacture is also disclosed.

    摘要： Methods of coupling a bearing assembly to a downhole tool include forming at least a portion of a downhole component from a diamond-enhanced material, applying a metal material to a surface of the downhole component using an ultrasonic molten metal process, and coupling at least a portion of the surface of the downhole component to at least another component of the downhole tool. Downhole tools include at least one component of a bearing assembly that is configured to move relative to a portion of the downhole tool. The at least one bearing component comprises a diamond-enhanced material and is coupled to a portion of the downhole tool by an ultrasonic molten metal process.

    摘要： An earth-boring bit has hardfacing that has multiple grades and an overlapped portion. One of the layers is of a different grade than the other so as to provide more wear resistance. The other provides more toughness than the wear resistant layer. The more wear resistant layer has a greater volumetric density of carbide particles. The greater density is primarily achieved by using a majority of the particles of smaller dimension than in the less wear resistant hardfacing. The overlapped portion may be on an outer or gage end of the outer row of teeth.
