Clamp for tool holder

A tool holder, comprising:

• a body including an insert-receiving pocket formed at a forward end thereof, the insert-receiving pocket having a bottom and at least one side wall for receiving a cutting insert, the forward end having a threaded clamp-receiving bore with a coolant opening for receiving pressurized coolant from a coolant source;
• a clamp including a body portion, a neck portion, and a tapered nose portion, the body portion including a top surface and a bottom surface, a threaded aperture extending from the top surface to the bottom surface, the clamp further including a plurality of clamp coolant passages in fluid communication with the threaded aperture, each clamp coolant passage having an outlet port;
• and
• a clamp screw threaded into the threaded aperture of the clamp and at least partially received in the threaded clamp-securing bore of the tool holder body, the clamp screw including a clamp screw coolant passage in fluid communication with the coolant opening of the body, and at least one coolant channel in fluid communication with the clamp screw coolant passage,
• wherein each of the clamp coolant passages includes a first section formed in the neck portion, and a second section extending from the first section to the outlet port,
• wherein coolant from the coolant source enters the coolant opening, travels into the clamp screw, travels into the clamp screw coolant passage, travels into the at least one coolant channel of the clamp screw, travels into each of the plurality of clamp coolant passages, and then exits through each outlet port in a direction toward a cutting insert-workpiece interface.
