A metal cutting tool holder includes a tool holder body having a first fluid passage extending in a first direction between a first inlet and a first outlet, and a second fluid passage extending in a different second direction between a second inlet and a second outlet. The tool holder body has a cavity and the first outlet and the second inlet intersect the cavity. A member is positionable in the cavity such that a curved third fluid passage connecting the first outlet and the second inlet is formed at least partially by the member. The curved third fluid passage extends from a first end adjacent to the first outlet to a second end adjacent to the second inlet. The first direction is tangent to the curved third fluid passage at the first end, and the second direction is tangent to the curved third fluid passage at the second end.
