APPARATUS FOR DRILLING RAILWAY RAILS
An apparatus (1) for drilling railway rails (2) comprises a supporting portion (8) supporting a battery operable electrical motor (3), a drilling tool (4) defining a tool axis (5) and a drilling direction (12), a reduction gear (6) interposed between the motor (3) and the drilling tool (4), a replaceable battery (7) and means (13) for removably fastening the supporting portion (8) to an object to be drilled, as well as a lighting system (14) having two light sources (15, 16) spaced from each other and arranged on two opposite sides with respect to a theoretical vertical working plane (17) containing the tool axis (5), wherein the two light sources (14, 15) generate two light cones at least partially overlapping in a drilling area (18) of the drilling tool (4).
