Coring tools having coring shafts with associated internal static sleeves

A sidewall coring tool assembly, comprising:

• a coring shaft having an internal cavity and configured to be coupled to a coring motor shaft of a coring motor at a first axial end of the coring shaft, wherein the coring shaft comprises a plurality of internal grooves disposed on an internal surface of the coring shaft, wherein the coring shaft comprises a plurality of scoops disposed circumferentially on a first external surface of the coring shaft, and wherein each scoop of the plurality of scoops forms a conduit from an exterior of the coring shaft to an interior of the coring shaft;
• a coring bit coupled to the coring shaft at a second axial end of the coring shaft;
• a plurality of fins disposed on at least one of a second external surface of the coring bit and the first external surface of the coring shaft;
• and
• a static sleeve including a first axial end and a second axial end, the first axial end positioned proximate the coring bit, the second axial end configured to be directly coupled to a stationary portion of the coring motor, the static sleeve disposed radially within the internal cavity of the coring shaft, wherein the static sleeve comprises a plurality of holes extending through the static sleeve and a plurality of fingers at an axial end of the static sleeve closest to the coring bit.
