Abstract
The present invention provides an instrument and a method for examining the condition of column-shaped or cylindrical sections of objects. It comprises a drive device having a drill chuck, which holds a drill needle that can be driven by the drive device, and a guiding device for guided insertion of the drill needle into the object to be examined. The guiding device is a telescopic tube that comprises a shorter inner tube section that is arranged in a longer outer tube section such that it is axially displaceable, and has a longitudinally arranged measuring scale on its outer circumference. The telescopic tube is placed on the drive device in non-rotating manner via the inner tube section. The inner and the outer tube sections have guiding means for centrally-axially guiding the drill needle, which extends in central-axial direction from the drill chuck through the inner tube section and through the outer tube section. When the inner tube section is being inserted into the outer tube section, the drill needle can be driven into the object to be examined in a manner guided by the guiding means.
