Patent number: 9670736Abstract: A bit body is configured at its upper extent for connection into a drillstring. At least one fixed blade extends downwardly from the bit body, and has a radially outermost gage surface. A plurality of fixed cutting elements is secured to the fixed blade, preferably in a row at its rotationally leading edge. At least one bit leg is secured to the bit body and a rolling cutter is mounted for rotation on the bit leg. At least one stabilizer pad is disposed between the bit leg and the fixed blade, the stabilizer pad extending radially outward to substantially the gage surface. The radially outermost gage surface of each blade can extend axially downward parallel to the bit axis or angled (non-parallel), spirally or helically, relative to the bit axis.Type: GrantFiled: May 30, 2013Date of Patent: June 6, 2017Assignee: Baker Hughes IncorporatedInventors: Anton F. Zahradnik, Ron D. McCormick, Rudolf C. Pessier, Jack T. Oldham, Michael S. Damschen, Don Q. Nguyen, Matt Meiners, Karlos B. Cepeda, Mark P. Blackman

Patent number: 8356398Abstract: An earth-boring bit comprising a bit body is configured at its upper end for connection into a drillstring. A fixed blade depends axially downwardly from the bit body. An axially extending slot is formed in the bit body adjacent the fixed blade. A bit leg is received and retained in the slot by engagement between the slot and correspondingly shaped bit leg, wherein the bit leg cannot be removed from the slot except by axial movement relative to the bit body. A rolling cutter is secured to the bit leg at its lower extent. A fastener secures the bit leg against movement relative to the bit body and extends through oblong apertures in the bit leg and into the bit body, the bit leg can be moved axially relative to the bit body to adjust the projection of the rolling cutter relative to the fixed blade.Type: GrantFiled: February 2, 2011Date of Patent: January 22, 2013Assignee: Baker Hughes IncorporatedInventors: Ron D. McCormick, Rolf Carl Pessier, Don Q. Nguyen, Tim King Marvel, Matthew R. Isbell, Anton F. Zahradnik, Karlos B. Cepeda, Michael Steven Damschen, Steven M. Winnon

Publication number: 20090272582Abstract: An earth-boring bit comprising a bit body is cofigured at its upper end for connection into a drillstring. A fixed blade depends axially downwardly from the bit body. An axially extending slot is formed in the bit body adjacent the fixed blade. A bit leg is received and retained in the slot by engagement between the slot and correspondingly shaped bit leg, wherein the bit leg cannot be removed from the slot except by axial movement relative to the bit body. A rolling cutter is secured to the bit leg at its lower extent. A fastener secures the bit leg against movement relative to the bit body and extends through oblong apertures in the bit leg and into the bit body, wherein the bit leg can be moved axially relative to the bit body to adjust the projection of the rolling cutter relative to the fixed blade. The slot defines a pair of generally opposed sides connected by a third side, the generally opposed sides being inclined toward one another to define a dovetail that corresponds with the shape of the bit leg.Type: ApplicationFiled: May 2, 2008Publication date: November 5, 2009Applicant: BAKER HUGHES INCORPORATEDInventors: Ron D.
