ABSTRACT:
In order to facilitate and make more ergonomic the drilling of a multitude of holes in workpieces, particularly in the assembly of large scale components, such as an aircraft body, the power drill is docked to a support by an attachment which engages and locks onto a guide bushing or bore in the support. The attachment assures that the drill bit is precisely axially aligned with a hole to be drilled. The feed advance is performed by a leveraged action controlled by the operator. The leverage can be provided, for example by a Bowden pull cable. The attachment reduces the exertion to be made by the operator, thereby avoiding ergonomically unsatisfactory work positions.
