Abstract
Diamond drag bits with a multiplicity of individual diamond insert studs standing-off from the face of the bit require fluid over and around each separate insert to cool and clean the stud. An axially aligned fluid passage formed within the insert stud communicates with a fluid-filled chamber formed by the drag bit. The fluid exits the passage in the stud in front of the diamond cutting face of the stud to assure cooling and cleaning of each insert stud inserted in the face of the drag bit.
