ABSTRACT:
A fluid seal device for preventing fluid from flowing around a tool secured to a tool holder by a collapsible collet having slots extending from a first end of the collet to a second end of the collet and a collet nut is disclosed. The tool has an inner chamber through which fluid is fed to a tool tip. The fluid seal device includes an O-ring positioned around the tool between the tool tip and the first end of the collet. A rigid seal is positioned about the drill bit and the O-ring, and is positioned between the first end of the collet and the collet nut such that fluid flowing within the slots of the collet is prevented from flowing past the rigid seal, thereby providing maximum fluid pressure within the inner chamber.
