How to drill into a wall of your home

For the activities of DIY home drilling of masonry walls wood or other materials is a task that recurs frequently.

Drill a hole for a job is a very precise operation, apparently, very simple but requires a minimum of technical knowledge and use of appropriate tools.

Drill or punch and hammer

All lovers of DIY at home have an electric drill with its own set of threaded ends, the functions that the device provides are generally related to the different ways by which drill the hole, the most common until the drilling rotation and percussion drilling.
Among the leading manufacturers of drills we can cite Black & Decker , Bosch , Makita .

A very simple task and often neglected, prior to drilling, the investigation of the kind of dumb on which they work.
The drilling rotation or simply rotary drilling should generally be used on walls made ??of hollow bricks and materials that offer a resistance, relatively low, the operation of penetration.

In this way, with the drilling rotation is prevented to realize holes too large or unnecessarily destroy part of the hollow bricks involved in the operation, similarly also the breakage of the finishing eo of the plaster around the edge of the hole are very contained.

In the case where the need to be conducted out of the hole of a wall consisting of compact materials and very resistant with respect to the perforated block (such as walls of concrete, solid brick etc.) Is appropriate to use the function of percussion drilling.

The function of percussion drilling (often referred to technically as roto-percussion) is characterized by the rotation of the tip associated with the frequent jokes made ??by the same or percussion drill. Most drills allow to simply activate one of the two functions by means of a switch. Typically the operation of punching a hole provides that has been rated the diameter of the same and chosen the most appropriate for dowel then laying the pressure screw.

It should be stressed that screws and dowels are proportionate to each other in correspondence of the function they have to perform, they are similarly proportional to the holes to be carried out, everything is necessary in order to guarantee the seal, to the load, provided by the manufacturers. A very common case is that of the typical extraction from the piece of the wall, with the increase of the applied load. Generally, the phenomenon occurs for anchors, screws and applied loads of bricks and in most cases is due to incorrect evaluation in the association hole, dowel, screw and load.

In carrying out the drilling, the drill must be held perpendicular to the surface of the wall to be drilled. May occur in practice some special cases, for example when attaching the plugs for retractable shelves or in special shapes.

In such cases it is appropriate to use the specific guides for drilling. In cases where it is in the presence of a non-plastered masonry, it is desirable, to avoid drilling in correspondence of the joint between the bricks.

Details laying pieces of perforated wall

The laying of a gusset, in the escape between the bricks, could give rise to a seal with characteristics of load bearable even less than half of those corresponding to a pose at the center of a brick. Both in the case of walls of finished walls which in their raw state, such as the one just described, before a puncture should also affect slightly the surface at the point where it must make a hole.

This simple device allows to avoid any slipping of the drill bit to the surface will work. Finally, we would emphasize the importance of having a clean hole before inserting the plug into it. A hole full of dust and debris processing can affect adhesion to surfaces and then seal the plug. The cleaning can be done trivially by blowing into the hole or using a brush of appropriate dimensions.
