At improvement of the apartment there is the need of fastening on walls and the ceiling of various objects – photos, pictures, lamps, mirrors, curtains, shelves, the TV, plinths and many other.
To hang up the photo or the small picture, of course, you should not drill the wall. It is enough to hammer the small nail. But not any tack is suitable for this business. It is the best of all to use dowels is nails of different length, thick and tempered. They can be hammered even into the concrete wall. Performance of operation of drilling of openings in walls at modern equipment by the electric tool will not present bigger difficulty if the nobility as it is correct to carry out drilling. And if apply the conductor to drilling without dust, it will save you from excess cleaning and will keep property in integrity. Than to drill the wall? The best tool, than the perforator, for drilling of openings in brick and concrete walls did not think up yet. But seldom who is able to afford luxury to have such expensive tool in economy. Usually buy the electric drill with function of shock action.
Choice of the drill
Upon purchase of the electric drill it is necessary to be guided by the following technical characteristics:
- power of the drill has to be not less than 600 W;
- turns - till 2500 a minute, and availability of the possibility of their slide control - from 0 to maximum;
- availability of the reverse of rotation (switch of rotation of the drill clockwise or counterclockwise).
- the boss is the best of all self-tightening, it will not be necessary to spend time for the clip of drills and search of constantly got lost key;
- diameter of the drills clamped in the boss - at least 10 mm;
- availability of the included function of drilling with blow.
Of course, the drill at inclusion of this function will not become the full-fledged perforator, but will drill walls much more simply and quicker. The brick, cement and concrete very well maintain the static load – pressure. But easily collapse from dynamic influences – blow. Karatekas easily break the brick in two the palm edge. When drilling the simple pressure of the drill occurs the drill without blow function, and it is heavy to the cutting edge to be hooked for material. Therefore process goes slowly and the drill from friction is strongly warmed. Absolutely in a different way there takes place drilling with blow. The drill at blow pricks out the cutting edge the part of material and, getting with blow to the formed deepening, breaks away the portion of particles of material. There is something like slotting by the chisel.
Choice of the drill
Walls from the tree, gypsum cardboard, foam concrete with success are drilled by the ordinary drill. Walls from the brick, the stone or concrete require already hard-alloy drill. It differs in the cutting edges which are welded on upon the normal drill from hard-alloy material from steel, usually the pobedit. More rare - artificial diamond. The Pobeditovy insert is well visible on the end of the upper drill. It is enough to have in economy of 2-3 pobeditovy drills with a diameter from 6 to 10 mm. Drills with pobeditovy building up it is possible to drill the opening no more than 10-15 cm in depth. For drilling deeply, for example for drilling of the wall through, use the drill. Drills for drilling of brick and concrete walls happen up to 1 m long and are intended for drilling of openings only by the perforator. At the drill even the cutting edges become not sharp, and rounded for increase in their wear resistance. Drills happen to diameter of the shaft (10 and 18 mm), to special grooves of the standard of SDS+ or SDS-max for fixing, but too are well clamped in the normal cam boss. The standard and diameter of the drill are beaten out on its shaft. If it is necessary to pass the drill the thick wall, for example 0,5 m thick, then pass is carried out in several stages drills of one diameter, but different length. It is necessary for safety and faster drilling. At first drill the wall the drill 20 cm long on depth of 10-15 cm, then longer drill on depth of 30-35 cm. Finish drilling with the drill 50 cm long. The drill for such work has to be rather powerful. Of course, the drill for such loading is not calculated, and its application only in exceptional cases is admissible. Better for performance of such works to hire the real perforator.
How to drill the wall?
Before starting drilling of the wall or ceiling, it is necessary to be convinced that under the planned place in plaster there do not pass electric wires or other cables. Otherwise it is possible to damage the electrical wiring and most to get under tension.
How not to get to the wire?
It is necessary to examine the wall regarding availability of the switch, the socket. Usually in the vertical direction wires to the distribution box depart from them up. But vertical position - the ideal case. This rule is seldom followed in practice by electricians: saving the wire, they lay often buried wiring on diagonal, in the shortest way. But the wire will pass all the same from the switch to the next box. The wire will depart from the chandelier to the next box too. Usually wires are drowned on depth no more than 10 mm. For check by rather blunt tool, for example the screw-driver to make a hole in the wall on this depth. If wires were not found, then it is possible to start drilling. And still, just in case, up to the depth of 20 mm it is necessary to press not strongly the drill, and after deepening visually to check each 2 mm whether the wire got. There are special devices allowing to define the place of passing of wires in the wall. Detection of the electrical wiring is displayed by blinking of the LED and the discontinuous sound signal. Such device is especially necessary when mounting false and stretch ceilings as load-carrying structures fasten on self-tapping screws at the ceiling, just where electricians, as a rule, lay wiring.
Drilling of openings in steel concrete
Brick walls are drilled by the pobeditovy drill without special work. Decided on the place, put the conductor and, strongly pressing the drill, drilled the opening. Happens, the burned-through brick which is drilled more slowly, dust not of red, but black color comes across in the wall. The main thing - to drill on small turns (200-400) with the included shock mode, pressing on the drill handle more feasibly and to watch that the drill did not overheat. The brick is not difficult to be drilled at all. Be careful, the drill at long drilling is warmed to high temperature, at touch to it it is possible to receive strong ожег. It is necessary to stop periodically drilling and to dip the drill into water. If the steel concrete wall is not made of cement of brand 600 or 500, then it is drilled also well, as well as the brick. In household construction apply only brand 400 cement. In houses of old construction the colons made of high-strength concrete sometimes meet. They are drilled very difficult and long. At production of concrete blocks for durability in them mount the iron armature welded among themselves mutually perpendicularly representing corrugated rods with a diameter of 8-15 mm and add granite crushed stone.
To Pobeditovy drill not in power to overcome such obstacle. But there is the simple decision. When drilling the drill suddenly ceased to go deep, so came across the armature or facets. The armature is successfully drilled by the ordinary drill. If you near at hand did not have the simple drill and is admissible to transfer the place of the opening, then it is possible to move on diagonal up or down. Granite pebbles crumble from blows to the drill or the narrow chisel inserted into the opening, the hammer. After each blow that there was no jamming of the tool and quicker there was the work, it is necessary to turn it on the quarter of the turn. After removal of the obstacle, drilling continues the pobeditovy drill. For the drill with the perforator granite pebbles are not the obstacle and are successfully drilled.
Drilling of the tile
Drill with hard-alloy weldings it is necessary for drilling of the tile (after the drilling point basting) previously to remove glaze.
It becomes very simply, the core, and in case of its absence, it is possible also the ordinary self-tapping screw or even the thick nail with the sharp end very easy blows to chop off glaze in the place of future opening and then to drill as the brick wall, on small turns.
Drilling of openings of big diameter in the wall
At the equipment of ventilating channels and extracts there is the need to execute in the wall the opening of big diameter, for example 18 cm. When it is necessary to hide the electric counter in the wall, it is required to make the niche in the wall. In house conditions such problem can be solved with the help of the hard-alloy drill. The pencil plans on the wall the contour of future opening. From outer side from the line of the marking openings by the hard-alloy drill diameter to the 8-12th with distance between edges of openings about 10 mm are drilled. For the opening in the wall with a diameter of 18 cm it is required to execute about 30 drillings with the diameter of drill of 10 mm. Further wall material selection by means of the chisel and the hammer becomes. With the smaller diameter of the drill, edge of the opening will turn out accurater, but it is necessary to drill more openings. If the wall thick and lengths of the drill is not enough for receiving through drilling, in that case it is possible to drill in 2 stages. If there is the opportunity to drill the wall from 2 parties, then at first carry out drilling as it is described above on the one hand walls, then in the geometrical center of the received selection in the wall the opening on the departure, that is through is drilled. Concerning the received opening the marking from the opposite side of the wall is carried out, and operation repeats. If drilling of the thick wall from 2 parties is not possible, then it is necessary to do drilling and selection in 2 stages. From the line of the marking from outer side one more line, at distance sufficient that after the first selection in the wall and further drilling the drill could go deep into the made niche is put, without touching edge of the wall. For reduction of labor input of work it is better to get the drill of sufficient length at once.
Drilling depth limiter
For control of depth of the received opening in the course of drilling it is possible to put on the drill of the drill the piece of the cambric (tubule) of the necessary length against the stop the cartridge. If you near at hand did not have the suitable cambric and it is necessary to drill small quantity of openings, then it is possible to use ordinary PVC the insulating tape, having reeled up several rounds on the drill. This simple adaptation will allow to accelerate work and will save you from need to stop drillings for measurement of depth of the opening.
The conductor for drilling of openings without dust
Because of heterogeneity of the walls which are especially executed from the brick, often the drill "takes away" from the planned place aside. As a result, if openings more than one, the suspended shelf hangs not horizontally or, what is even worse, it cannot be hung up as the established dowels do not match fixing loops. It is possible to use the conductor in the form of the sheet of plywood with in advance drilled opening, but when drilling from vibration it can be displaced too, and again the result will turn out not that which was expected. But there is the simple technology allowing to drill 2 and more openings in the set places.
Exact drilling of openings
To solve the problem it appears it is possible very simply, having pasted on all area of the party of the conductor which is put to the wall, the leaf of any emery paper. At the same time coupling of the conductor with the wall surface repeatedly increases, and when drilling the given accuracy of positioning is provided reduced. The opening will turn out precisely in the place of the marking. Depending on the weight of the product and density of the wall, it is necessary to drill openings under dowels of different diameter - usually 6 or 8 mm. For universality in the conductor it is necessary to drill the ordinary drill several openings of desirable diameters. In completion follows to the end face of the basis of the conductor to attach the plate at right angle. Thanks to such completion the most part of products of drilling will remain on this shelf that will prevent pollution of wall-paper and will reduce dust diffusion extensively.
The offered adaptation is irreplaceable also when drilling openings for fastening of plinths. The opening in the conductor is drilled at specified height from the shelf. When drilling you put the shelf on the gender, and all openings of you to turn out strictly at the necessary height from the floor that will be the guarantee of the dense prileganiye of the plinth to the floor surface. Sometimes it is necessary to hang up the product for which it is necessary to drill several openings in the wall on the wall and to sustain distance between them with the bigger accuracy. If the wall brick and plastered, then without conductor it is impossible to execute exact drilling. The board, the sheet of plywood or metal will be suitable for production of the conductor for exact drilling. After the marking in the leaf the necessary quantity of openings is drilled by the ordinary drill. Let's consider the case for fastening of the product on 2 screws. One opening is drilled by diameter equal to diameter of the drill, the second - diameter equal to diameter of the self-tapping screw. After the conductor is made, with its help in the wall the first opening into which the dowel is hammered is drilled. The self-tapping screw in the hammered dowel fastens to the wall the conductor, is leveled by means of the water level that the drilled openings were on one horizontal. Thanks to application of the most ordinary conductor who it is possible to make in several minutes of any improvised material openings turned out precisely at the set distance from each other. On the same technology it is possible to drill also a number of openings on bigger removal from each other. In that case at first extreme openings are drilled on above to the described technology, the conductor is fastened by 2 extreme self-tapping screws, and then all other openings are verified. The offered options of conductors are convenient at apartment renovation when everywhere construction debris. However when repair is finished and purity is induced, drilling turns into the stress. There is no wish to soil carpets and furniture with the concrete or brick crumb and dust at all.
Drilling without dust
During drilling of walls, especially the ceiling, flour and grains of sand of the drilled material scatter on all room. It occurs because in the drill for cooling of the engine, the impeller which rotating is installed, sucks in in the drill body air from the handle, and throws out warmed up in the zone of his boss. This measure allows to make the drill of bigger power at small dimensions and to protect the mechanism of the drill from dust. And the question of how to protect the dwelling from dust when drilling, is left for the decision to the owner. There is the simple design, позволяющуя to drill without dust.
The conductor for drilling without dust represents modifed previous option, but the shelf is replaced with the part which is cut off from the plastic bottle. The piece of plywood (9-11 layers) 80х150 mm in size is cut, at distance of 30 mm from edge on the axial line the opening by diameter equal to diameter of the drill plus 1 mm is drilled. From outside, on which the emery paper will be pasted, trapezoidal selection of 2-3 layers in depth of plywood becomes. Selection will serve as the peculiar air inlet when drilling. From the plastic bottle the part so that remained it was possible to fix on the conductor is cut. Width of the basis of the conductor is chosen proceeding from the bottle sizes. We take the square bottle, but any of 1,5 l will approach. The insulating tape before obtaining the size equal to inside diameter of the inhausting vacuum cleaner pipe is reeled up on the threaded part of the neck of the bottle. When bending the bottle, for forming of the required configuration, openings are formed. We close them pieces of the remained plastic and we fix by the clerical stapler. It is possible to close them the adhesive tape. The tightness is not necessary here. Gaps will not play several millimeters of the role as the inhausting force even of the low-power vacuum cleaner is excessive. Then by means of the furniture stapler, on perimeter of the end face of the basis of the conductor, from outside, where the emery paper is not pasted, the created part of the bottle is fixed. In the bottle we make the opening under the drill. It is better to apply the melting method as the edges forming the opening will become thickness and will longer serve. It is possible to melt the opening the soldering iron or warmed on the gas stove to it is red the nail. We connect the vacuum cleaner, we include the minimum power of suction, we do trial drilling. The result very much will please you. You will not find any mote in the district, dirt on the surface of drilling!Top
