A pressing-out apparatus ( 4 ) for pressing out a mass from a self-drilling, chemical composite anchor ( 2 ) for mining and tunnel construction has a pressing device arranged in a housing ( 21 ). The composite anchor ( 2 ) includes an anchor tube ( 5 ) having one end ( 6 ) with a drilling head ( 7 ) and one free end ( 8 ) and can be drilled into the receiving material by means of a motor ( 3 ). The pressing-out apparatus ( 4 ) is operatively coupled with the motor ( 3 ) and with the free end ( 8 ) of the anchor tube ( 5 ).
