| description | A drill bit according to one embodiment includes a center member configured to rotate at a first speed and an outer member disposed outside the center member, wherein the outer member is configured to rotate at a second speed. The drill bit also includes a first cutter disposed on the center member and a second cutter disposed on the outer member, wherein the first speed and second speeds are configured to control a resultant side force of the drill bit.
Un trépan selon un mode de réalisation comprend un élément central conçu pour tourner à une première vitesse et un élément extérieur disposé à l'extérieur de l'élément central, l'élément extérieur étant conçu pour tourner à une seconde vitesse. Le trépan comprend également une première haveuse disposée sur l'élément central et une seconde haveuse disposée sur l'élément extérieur. La première vitesse et la seconde vitesse sont réglées de manière à commander une force latérale du trépan. |
