1. A tooling assembly for a machine having an automatic tool changing system, the tooling assembly comprising:
a tool body disposed about a rotational axis, the tool body defining a first internal passage operable to have a coolant fluid flow within, wherein the first internal passage includes an inlet, a stem channel, a first curved channel, and a first outlet,
wherein the inlet is configured to receive the coolant fluid from the machine,
wherein the first outlet is open through an exterior of the tool body,
wherein the stem channel is in fluid communication with the inlet and ends at a beginning the first curved channel to provide the coolant from the inlet to the first curved channel,
wherein the first curved channel is in fluid communication with the stem channel and the first outlet to provide the coolant from the stem channel to the first outlet, and the first curved channel extends from the stem channel to the exterior of the tool body,
wherein at least one portion of the first internal passage tapers from a first diameter to a second diameter, the first diameter being greater in size than the second diameter and located upstream of the second diameter, and the second diameter being located at the exterior of the tool body where the first outlet is located,
wherein the at least one portion of the first internal passage includes at least part of the first curved channel,
wherein the stem channel has an end diameter, where the stem ends, that is equal in size to a beginning diameter of the beginning of the first curved channel.
