Abstract
A drill bit includes a bit body; a plurality of gouging cutters rotatably mounted to the bit body so as to define a first profile; and a plurality of gouging cutters non-rotatably mounted to the bit body so as to define a second profile. The first profile is longitudinally ahead of the second profile in a direction of drilling of the drill bit by a selected distance.
Claims29
A drill bit, comprising:
- a bit body;
- a first plurality of gouging cutters mounted to the bit body on respective posts in the bit body so as to define a first profile;
