Abstract:
A spindle of a drilling tool includes a socket portion having a first axial length (a 1 ) of a first diameter (d 1 ) for receiving and attaching a drill bit to the spindle. The spindle includes a fluid conduit having a second diameter (d 2 ) narrower than (d 1 ) for conveying a fluid to the socket portion. An interface space with diameter (d 1 ) is formed between the fluid conduit and the drill bit when the drill bit is installed in the socket portion. A fluid conveyor, having a third diameter (d 3 ) narrower than (d 1 ), connects the fluid conduit to the drill bit to avoid fluid gathering in a periphery of the interface space. The fluid conveyor includes a first O-ring abutting a mouth of the fluid conduit, a second O-ring abutting a mouth of a fluid channel of the drill bit, and a spring between the first and second O-rings.

Claim (Index 19):
A drilling tool, wherein a fluid is conveyed through an interior of a drill bit to a drilling zone, comprises a spindle according to  claim 9 .
