Abstract: A tool holder (e.g., shrink fit adapter) with fluid directing passages includes a shank and a fluid/coolant directing structure including one or more nozzles fluidically connected to feeder channels of the shank. The one or more nozzles each include an inner wall and an outer wall configured/shaped to direct fluid/coolant flow both radially inwardly and longitudinally distally and/or to variably modulate fluid/coolant flow around a nozzle outlet of or provided by the nozzle(s) in relation to a longitudinal central axis of the shank. The fluid/coolant directing structure incorporates one of more of: a ring of peripherally located nozzles having geometries/orientations configured to focus and direct thin sheets of fluid/coolant both radially inwardly and distally longitudinally; manifolds for directly feeding nozzle inlets of distally located nozzles; and a nozzle provided by approximately sinusoidally varying surfaces circumferentially disposed about a tool receiving recess of the tool holder for correspondingly variably modulating fluid/coolant flow direction through and exiting from the nozzle.
