Abstract

A hole is drilled in reinforced concrete 10 by means of a twist drill mounted in a drilling machine preferably of the percussive type. If the drill bit comes into contact with a steel reinforcement it is replaced by a rotary chisel tool 15 having a number of annularly arranged cutting edges 18 made from tempered steel, and guide surfaces 20 forming at least part of a cylinder, and the chisel tool is used for cutting its way through the steel reinforcement. After that the drilling operation may be continued by means of the twist drill. <IMAGE>
