Abstract
To prevent foreign bodies or lost circulation material in
drill mud locking the nozzles of a rotary drill bit, the central
passageway incorporates a separating means arranged to
separate larger particles from the drill mud and to divert them
away from the nozzles and out of the bit. The separating
means is arranged to operate in a static or dynamic manner.
