Abstract
A reaming tool includes a tool body having an axially rearward shank portion and an axially forward cutting portion, the forward cutting portion having at least one peripherally arranged cutting insert. The reaming tool also includes an inlet coolant channel formed in the tool body and an inlet opening at an axially rearward end of the shank portion. An outlet coolant channel is formed in the tool body and is in fluid communication with the inlet coolant channel, wherein the outlet coolant channel defines an outlet opening proximate to the cutting insert. In one particular aspect, at least a portion of the outlet coolant channel is non-linear. A method of making a component of the reaming tool by performing a printing operation on a substrate to form the component is also provided.
