Claims9
A rotating tool comprising:
- an inner housing;
- an outer housing;
- a clutch positioned between the inner housing and the outer housing, the clutch coupling the inner housing and the outer housing, the clutch being configured to allow the inner housing to freely rotate in a first direction without rotating the outer housing in the first direction and rotate the outer housing in a second direction when the inner housing rotates in the second direction;
- bearings positioned between the inner housing and the outer housing to distribute a rotational load between the inner housing and the outer housing;
- and
- a bottom sub with a first sleeve, second sleeve, and a communication port, wherein the first sleeve is configured to slide from a first position to a second position to expose the communication port, wherein the bottom sub is configured to rotate responsive to the outer housing rotating.
