摘要： A portable drilling machine for in situ drilling of a hole in the webs of a rail (10) for a railway track has a base (12), a drill (20) movable with respect to the base for drilling a hole in the web, a former (30) adapted to be received between the flanges of the rail to locate the machine on the rail and a clamping jaw (18) engageable with the opposite side of the rail web to clamp the machine on the rail.
The former (30) is rotatably mounted on the base (12) to a plurality of predetermined positions, in each of which the former offers a different profile, whereby the former can engage a plurality of different rail sections. The former may comprise two identical former templates (30), each of which is rotatably mounted on the base to a plurality of predetermined positions.
