  • Methods of forming earth-boring tools utilizing expandable reamer blades
    Patent number: 10047563
    Abstract: An earth-boring tool includes a tool body of a fixed-blade reaming apparatus configured to be coupled within the drilling assembly. The tool body has a longitudinal axis and at least one reamer blade configured to be outwardly extendable for use in an expandable reamer and attachable on a fixed-blade reamer. The at least one reamer blade is attached to the tool body in an immovable manner relative to the tool body during use of the earth-boring tool in the formation of a subterranean wellbore.
    Type: Grant

  • Reamer blades exhibiting at least one of enhanced gage cutting element backrakes and exposures and reamers so equipped
    Patent number: 9739094
    Abstract: A downhole tool configured to enlarge a borehole may include at least one blade extending laterally from a central portion of the tool. The one or more blades may each include a gage portion, and cutting elements comprising substantially circular cutting faces may be affixed to each of the one or more blades. Each of the one or more cutting elements may include a cutting edge comprising an arcuate peripheral cutting face portion for contacting the borehole. Cutting faces of at least one cutting element on a gage portion of the at least one blade may exhibit a cutting face back rake angle greater than a cutting face back rake angle of cutting elements on at least one other portion of the at least one blade.
