Concrete drill specially equipped for drilling holes in walls and ceiling beams of concrete, through which corrugated electrical pipes are to be passed. After drilling is completed, the corrugated outer pipe hose is applied to the drill so that the hose can easily be passed through the wall. The method also has the advantage of not running the risk of getting any rubbish in the hose at he bushing.

Adapter developed for corrugated electrical pipes, that are to be installed through walls and ceiling beams. Developed to quickly and easily move the corrugated electric pipe through the pre-drilled hole. The method also has the advantage of not running the risk of getting any rubbish in the hose at he bushing.

* Use the adapter with the drill in the drill before drilling starts.
* After drilling through the wall, remove the drill.
* Attach the corrugated outer pipe hose and inner pipe so that the hose can be easily passed through the wall.

Adapter developed for plumbing tap water system with pipe-in-pipe system, to be installed through walls and ceiling beams. Designed to quickly, easily and in a moment be able to bring both the corrugated outer pipe and the inner pipe of Pex/Alupex through the hole. The method also has the advantage of not running the risk of getting any rubbish in the hose at he bushing.

* Use the adapter with the drill in the drill before drilling starts.
* After drilling through the wall, remove the drill.
* Attach the corrugated outer pipe hose and inner pipe so that the hose can easily be passed through the wall/soffit.

Probe that is mounted on either the electric hose adapter or the pipe-in-pipe system for tap water, so that the hose and inner pipe can easily be passed through the wall/soffit in an already pre-drilled hole. The method also has the advantage of not running the risk of getting any rubbish in the hose at he bushing. The end of the probe has a 4 mm hole for the usual passing through of cables.
