may seem that to drill a hole in the wall - a piece of cake.However, if you choose the wrong tool for this or that material surface drill may blunt or even break and may appear on the surface scratches and cracks.To avoid this from happening, you need to know certain nuances of the performance.How to drill, how to correctly prepare the surface and to pick up a drill, consider further.

General recommendations for drilling holes

tools to properly handle.The drill must be positioned directly in the surface and go in a vertical direction.To make it easier to carry out drilling and more accurate drilling, you can use the auxiliary handle, which usually comes with the drill.

Recognizing what type of surface you are working, you need

to pick up the material and the size of the drill and to determine the mode of operation of the tool.

That is the main principle of how to drill: the material of the cutting tool must be harder than the material drilled surface.Imagine the following situation.Let's say you decided to drill a wall of concrete using a drill designed for wood.You can be sure that nothing good will come out, and have to throw the drill.Therefore, the type and material of the drill should be carefully selected for each type of surface.

Drilling concrete wall

Step 1. Selection of the drill. If the surface of brick, stone or concrete, the drill must be taken carbide.Typically used for such purposes pobeditovye drill.They do not cut the material and turn it into crumbs, so concrete or stone walls fit perfectly.However, in order to form a hole in the plastic, wood or steel, they are not intended.If you try to drill to drill pobeditovym wooden wall, wood fibers are torn, and the hole will be ugly, sloppy and larger diameter than is necessary.Drill steel with such a drill does not succeed.

Step 2. surface preparation. Before drilling the wall, make sure that in this area there is no wall wiring, heating and plumbing pipes.For this purpose, it is more convenient to use a metal detector.It reacts both to the iron and steel objects, and the objects made of ferrous metals.With the help of a metal detector can be found, where the electric cables, and to determine at what depth you can perform drilling.

holes with a diameter less than 13 mm perform drill and wider hole - puncher.However, several large holes can be drilled with a drill and, if the cartridge is suitable for conical drill diameter of 13 mm.

Step 3. drilling process. is first necessary to outline in what place will be a hole.It does not matter if you're using an impact drill or a hammer, in some cases, to start drilling you need to put the device in a simple mode of drilling without impact on small speed to make recess.It is easier to start drilling, the drill will not jump on the surface and you will be able to produce more accurate drilling.And after you have identified the place of the future holes can go into shock mode and add momentum.

If you are using plastic anchors, the hole should be deeper than the length of the dowel.Typically in the process of drilling a hole remains a certain amount of crushed material in the form of dust, you must leave a margin of 10 mm length.

Those who repeatedly worked with the drill, knows that to keep it in the desired position is sometimes difficult.The tool itself is heavy, in addition to this operation, vibrations occur and flying dust.To avoid dust on the operator and the tool itself on the market today, there are special dust collectors.

Drilling metal

Step 1. Selection of the drill. To perform a neat hole in the metal surface should buy quality drill for metal.Cheap drills in this case should not be used because they are not only drilled foundation, but also deliver a lot of hassle.So try to buy a proven, high-quality drill-known manufacturers.The normal price for a good drill - about 300 rubles.

Step 2. surface preparation. Before drilling metal, you must stake the middle of the hole to the drill bit from slipping off the surface.This work is performed by a punch, which is a sharp metal rod.Strike the tool with a hammer, and it beats the edge of a recess in the surface.Through this drill will be fixed in one position, and the hole will correct and accurate.

Step 3. drilling process. To make a hole in the metal, whose thickness exceeds 5 mm, it is desirable to use several bits.Initially, work is done with a small diameter drill bit, and then dosverlivayut large drill to the desired diameter.Please include a drill for small momentum, then build up more speed.

to drill metal was easier, it is advisable to put a board under it.This will make the hole more smooth and accurate.

When the processing is performed metal drill bit heated.It is advisable to lubricate his work with a special paste or liquid cooling.If you do not, your regular motor oil.The exception to this rule is the gray cast iron, which is always drilled dry.

To pull the drill bit from the resulting hole, the drill must be turned in the opposite direction, if its mechanism is a function.

often used for drilling metal drilling rack, which is attached to the instrument.In this case, at the beginning of its handle to be pressed only slightly, and when the chip will, pressing force should be increased.

There is a direct correlation between the thickness of the drill and speed of the tool.Note that the larger the diameter of the drill, the lower speed.For example, if you are using a drill bit 4 mm in diameter, turns the instrument is about 2400-2800 per minute.If the drill diameter of 6-8 mm, speed is significantly less - approximately 1200-1300 per minute.

Drilling tiles

More overcame in a separate article as drills ceramic tile - select the tool and drill all the rules:

Step 1. Selection of the drill. There are special drills to work on ceramics and glass.You can replace them with a drill on concrete surfacing of pobedita if you have certain skills.This drill on concrete should be not too shabby.

Step 2. surface preparation. Tile quite slippery and hard, but at the same time fragile.In that case, if you use an ordinary drill bit for drilling in concrete, to perform work on the tile difficult, because the bit begins to slip and scratch basis.To avoid problems in the process, on the site where the hole will be made, it should stick a piece of adhesive.If you are using a special drill for tile, you do not need to do this, the only thing that if it needs to be blunted erode.

Step 3. drilling process. Now consider how to drill tile.Drilling himself tiles with hammer mode it is impossible not to split the glaze.Please perform drilling tiles.The force of pressure should be small.Perform at low speeds.After tile drilled include stroke mode and make a hole in the wall.If the tile drill drill special ceramics, after the passage of the tile it is replaced on drill pobeditovym tip.

Drilling chipboard and wood

Step 1. Selection of the drill. holes less than 10-12 mm in diameter is usually performed drill for metal.Special drill bits for wood need to buy only when the diameter of the hole is large enough, or when placed high demands on the quality of work.

drills are several types of wood:

  • spiral;
  • single- (twisted);
  • ring (crown);
  • feather;
  • cylindrical drills Forstner.

If you are a cross-drilling, use a center drill, and if longitudinal - the spiral.

Step 2. surface preparation. In the middle of the hole make an indentation with an awl to drill from slipping.To after the tool did not arise chips on the reverse side of the board enclose the bar.

Step 3. drilling process. perform at low or medium speed.DSP has a particularly fragile structure, so to avoid unstuck used drills with sharp edges and enclose a foundation block.
