Abstract
A cutting tool includes a body having a forward end and a rearward end. The forward end includes an insert-receiving pocket. The body further includes a coolant delivery system comprising a main coolant passage having a main coolant inlet extending from the rearward end toward the forward end, a primary coolant passage in fluid communication with the main coolant passage and having a primary coolant outlet exiting from the insert-receiving pocket, and a secondary coolant passage in fluid communication with the primary coolant passage and having a secondary coolant outlet exiting into the insert-receiving pocket. The primary coolant outlet intersects the secondary coolant outlet to form an outlet having a substantially non-circular shape. As a result, the coolant fluid exiting the outlet is in a fan-like pattern and is evenly distributed over the cutting edge of the insert.
