A process for controlling and a core drilling machine ( 1 ) having an electrical motor ( 2 ) for rotational drive of a core drill bit ( 3 ) having cutting edges ( 5 ) oriented axial to a work piece ( 4 ), a feeding means ( 6 ) for generating the feed of the core drill bit ( 3 ) against the work piece ( 4 ) and having a controller ( 7 ) for controlling, relative to a first one-to-one control parameter, detected by a sensor ( 8, 8 ') for electrical power consumption (P) or torque (M). A force sensor ( 9, 9 ') is connected to the controller ( 7 ) for detecting the contact pressing force (F<SUB>N</SUB>) of the core drill bit ( 3 ) as the second control parameter.
