The invention relates to a support and coupling structure for a portable drill for railway tracks. It comprises two guide rails (1) provided with racks (10), a vice (3, 3'), a support (5) and manoeuvring means (6). The vice (3, 3') has a first and a second jaw (7, 8) inferiorly shaped such as to grip the upper flange of the rail (4) and superiorly equipped with a strike and a counterstrike plates (74, 84). The jaw (7) is laterally fixed between the guide bars (1) and rests on the rolling plane (40) of the rail (4). The second jaw (8) is connected to the first jaw (7) by means of a flathead pivot (9), with a counterspring (12) and a key (100). The support device (5) comprises an adjustable drill (2) support device and sliding seats (51) on the guide bars (1). The manoeuvring means (6) comprise first gears (60) enmeshing with the racks (10) and keyed on a first shaft (61), which shaft (61) is also equipped with a handle (62) and second gears (63) enmeshing with the first gears (60) and keyed on a second shaft (64) equipped with a turning handle (66). <IMAGE>
