Abstract
A clamp for a tool holder is disclosed. The clamping tool holder includes a body having an insert-receiving pocket and a threaded clamp-receiving bore with a coolant opening for receiving pressurized coolant from a coolant source. A clamp includes a threaded aperture extending from a top surface to a bottom surface and coolant passages in fluid communication with a coolant header. A clamp screw is threaded into the threaded aperture of the clamp. The clamp screw includes a plurality of coolant passages in fluid communication with the coolant opening of the body, and at least one coolant channel in fluid communication with the coolant passage. Coolant from the coolant source enters the coolant opening of the body, travels into the clamp screw, travels into each coolant passage of the clamp, and then exits the clamp in a direction toward a cutting insert-workpiece interface.
