In this article we will tell how to drill various materials correctly with a drill: metal, tile, concrete, glass, wood. Work with wood, metal, concrete and tiles has its own subtleties. If you follow some principles, the holes will be smooth and high quality.
In order to drill metal correctly, you need to know the properties this stuff. It is very hard, hard to be mechanically stressed and requires drills of a certain strength. If the drills are bad, then the work will not work. It is not recommended to save on tools, because a poor substandard tool can destroy the material.
Drilling thin metal sheets is a real flour for most craftsmen. Steel tends to break out, which can lead to serious injuries. To prevent this from happening, sheets of steel must first be fixed. To do this, you can make a special device that will clamp the steel.
For even holes, put a piece of rubber under the steel sheet. It is noted that when drilling large holes, the steel around can break down, creating scars. Rubber will prevent it.
When cutting a deaf thread, different garbage often gets into the hole. To eliminate this phenomenon, it is necessary to pour a little paraffin or wax inside.
Choosing a drill
The tile is a very fragile material. Wrong movement - and it can just break up. To properly drill tiles, you must follow simple rules. First of all, it is necessary to pick up special drills that have soldering from carbides. This will reduce the load on the work surface and ease the drilling process.
The point where it is necessary to make a hole must be marked in advance. This is done by taps or markers. Such a point will ensure that the drill does not slip. The mark is made on the outside of the tile.
We drill tiles
Sometimes it is necessary to drill a tile that is already glued to the surface. In this case, you can use drills for glass. When drilling a tile there are no special secrets. The main thing is not to make too much effort, otherwise the tile will crack. The better the drill, the easier the process is.
Drills with pointy tips Holes in concrete may be needed for a variety of purposes. The need for them may arise during normal repairs. For example, holes in a concrete wall are required when installing a toilet bowl and other plumbing, to install shelves and sliding doors. There are plenty of examples when you need to use a drill to work with this material. Concrete has its own special properties, therefore, work with it is also carried out according to certain rules.
How to drill concrete? For this purpose it is necessary to purchase drills with pobeditovye tips.
It must be remembered that the drill is used in working with concrete only for drilling holes of small diameter (up to 12-13 mm). If you need to make a larger hole, it is better to use a punch.
When drilling in concrete, the most frequent problems are breakage of drills and their jamming. Drills can also get clogged, so they should be regularly cleaned and sharpened.
Dust will not fly in all directions if you put a box or a can on the drill while drilling a hole. Then, when working, concrete dust will be collected in the tank.
The drilling process is as follows:
Wood is a soft natural material which is perfectly amenable to mechanical stress. However, in working with a tree it is necessary to observe a number of rules.
When working with wood, it is not the drills that often suffer, but the wood itself. You should not press too hard on the material, some types of boards can split from it or go cracks. This is especially important when making large holes. Drills for wood are suitable for the number of inexpensive.
