How to drill a drill - metal, concrete, tile

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.

Metal drilling

Metal

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.

Drilling a tile

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.

Concrete drilling

Concrete wall

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:

1. First, a point is marked at which a hole will be made.
2. Then you need to make a small indentation using a standard drill at this point.
3. Is the recess ready? So, it's time to change the usual drill to asymmetric. It will allow you to work more efficiently.
4. If a hole is made under the dowel, then it should exceed its size. Because concrete dust will significantly reduce the free space.
5. It is better if the drill used in the work has a built-in level. The one who has already drilled the concrete knows how hard it is to constantly maintain an even position of the tool. Especially if the work is long.
6. When working, the drills can be regularly moistened with plain water. This facilitates the process.

Drilling wood

Wood

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.

1. Making holes in logs, it is better to fix the material. Because otherwise the master risks losing the drill.
2. If you need to make holes in small pieces of wood, you can put ordinary emery under them. Then the details will not slide.
3. The burrs after drilling can be removed by wrapping felt around the drill.
4. Wood has many varieties, and each of these varieties has its own characteristics. For example, plywood almost does not lend itself to ordinary drilling, it can easily split. To avoid this, it is necessary to use not the usual drilling, but a tool resembling an external potato peeler. If you sharpen a steel tube, you can make many excellent holes in the plywood.

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.
