ABSTRACT:
A tool holder with a coolant inducer and a quick acting locking mechanism is disclosed. The holder body is provided with a tapered bore to receive the tapered shank of a cutting tool. The tapered shank has cam surfaces for engagement with locking pins in the holder body to cam the shank into drive transmitting and fluid-tight engagement with the tapered bore. A locking mechanism locks the tapered shank in the camming relationship with the locking pins and a retaining mechanism holds the mechanism in its locked position. A coolant inducer comprises an inducer ring at the upper end of the holder body and defining a fluid-tight chamber therewith. A fluid conduit is connected through a fitting in the inducer ring to the chamber which communicates with the upper end of the tapered bore in the holder body. A passage extends from the upper end of the tapered shank of the cutting tool in communication with said bore to the lower end of the cutting tool whereby coolant is supplied from the upper end of the tapered bore to the upper end of the tapered shank and a fluid-tight seal is provided by the engagement of the tapered shank and bore.
