Abstract
A coolant bonnet for a cutting tool includes a head portion, a shank portion, an internal coolant passage extending through the shank portion and into a coolant manifold disposed within the head portion, and one or more coolant ducts extending radially outward from the manifold to an outlet port. Each coolant duct is aligned with the chip flutes of the cutting tool and directs coolant at a predetermined exit angle in an axially rearward direction toward the cutting edges of a cutting insert mounted on the cutting tool. A method of providing coolant to a cutting edge of a cutting insert mounted on the cutting tool is also disclosed.
