Abstract
A rotary steerable tool may include a tool body with an upper end and a lower end. Additionally, the tool body may include at least one steering assembly extending from the tool body and includes at least one steering actuator configured to extend beyond other portions of the steering assembly. Furthermore, at least one cutter may be disposed on the rotary steerable tool a distance from the at least one steering actuator.

A rotary steerable tool, comprising:
- a tool body, wherein the tool body has an upper connection end and a lower connection end, the lower connection end including a pin connection or a box connection;
- at least one steering assembly carried by the tool body and extending radially from the tool body, the at least one steering assembly comprising at least one steering actuator configured to extend radially beyond other portions of the steering assembly;
- and
- at least one cutter on the rotary steerable tool a distance from the at least one steering actuator, the at least one cutter positioned between the upper connection end and the lower connection end of the tool body carrying the at least one steering assembly,
- wherein the rotary steerable tool, excluding the at least one cutter, has a first diameter when the steering actuator is not extended, and the at least one cutter is at a diameter greater than the first diameter.
