1. A medical drilling device comprising:
a housing comprising:
a hand-held portion;
an engagement portion; and
an actuator;
an axial drive element extending through the housing between a proximal end of the housing and a distal end of the housing;
a first drive element coupled to the axial drive element;
a rotational drive element extending through the housing between the proximal and distal ends;
a second drive element coupled to the rotational drive element;
a coupler interchangeably connected to a working tool and the rotational drive element, wherein the coupler extends beyond the engagement portion of the housing;
a first sensor comprising a transducer interfaced to the axial drive element, the transducer configured to measure a depth of the working tool into a bore, the transducer configured to output a first signal representative of advancement of the working tool relative to the distal end of the housing, wherein the first sensor measures a distance of the advancement of the working tool beyond the distal end of the housing; and
an electronics package in electronic communication with the transducer, the electronics package including a second sensor configured to output a second signal representative of passage of the working tool through layers of tissue having differences in material strength.
