SDS drill - the usual process of pulling back the outer sleeve of the SDS chuck should release either the bit or the chuck shaft so it virtually falls out or it can be easily withdrawn by hand - usually...

If its leaking water in front of the bearing replace always all oilseals and gaskets in the front of the tool much more is most case not neccesary.
