Before drilling the wall, you should definitely check if there are water and steam heating pipes or electrical wiring in the selected place. The best way to do this is with a metal detector. This device reacts to steel, iron and non-ferrous metals. It indicates the approximate drilling depth and signals the presence of live electrical cables.

Deep dust-free dowel holes

For plastic dowels, the depth of the holes must be greater than the length of the dowel itself. 10 mm is a sufficient margin of safety if, despite careful removal, drill dust still remains in the dowel hole. You can use a dust extractor or simply blow out the hole, but make sure that the drilling dust does not get into your eyes. If you want to remove dust even more thoroughly, use a vacuum cleaner.

To make it easier to drill in metal

On a surface as smooth as metal, your drill can easily slip off and you will not drill where you wanted. To prevent this from happening, punch a small hole in the metal before drilling. Usually, for this, a center punch is taken - a steel rod with a sharp point at the end, which is driven into the part from the back by a hammer blow. In this small groove you install the drill. If the material is hard, you can first make a hole with a thin drill, and then expand the hole with a drill of the required diameter.

Hold the instrument correctly

Always keep the drill straight and insert it vertically into the surface of a wall or part. If you work with an additional handle, it will be even easier for you to control the drilling process.

Sensitive organic glass

Holes in plexiglass must be drilled slowly, with a minimum number of revolutions - this material is very sensitive to heat and can melt.

Plaster for ceramic tiles

Old advice for the DIYer: The drill slides easily on a smooth tile surface - but this can be avoided by sticking a plaster or a piece of adhesive tape on the place of the future hole before work.
