We disassemble the peculiarities of the saber, chain, circular saws, saw alligators and jigsaws.
During construction or repair, it is often necessary to break a wooden timber, to shorten the board, crop OSB plates or cut a metal profile. For such work, a variety of types of power tools have been created. Let's try to find out which tool it may be necessary for work.
Types of saw on the principle of work
The saw power tool can be divided into three types depending on the principle of its operation: a tool with a reciprocating mechanism (jigsaws, saber saws, alligator saws), disc (circular) and chain saws. Each type is designed to solve its circle of tasks. The jigsaws allow you to make complex, curvilinear feeders of almost any materials - wood, plywood, chipboard, OSP, MDF, other composite materials, plastic, non-ferrous metals, steel, ceramics, rubber, foam rubber, cardboard, sandwich panels, profiles, etc. (except asbestos-containing materials). Lobzik is probably useful at the stage of finishing work: cut the hole for washing in the tabletop, do the holes for the ventilation decisions, to trim on the place of laminate when laying, cut the hole in the ceramic tiles - here is not a complete list of options for its use.

Sabelle saws
Sabelle saws were originally created as a tool for dismantling construction objects - and in this regard they are very comfortable. This compact tool allows you to cut a tree, metal, light foam and aerated concrete, and in difficult conditions of limited space. The rechargeable saber saw is simply indispensable in roofing, when the maintenance of the root. Also this tool is very convenient and for trimming in the garden of bruises and thick branches.

When working, the saber saw should be given not too strong vibration, which is best to evaluate when buying, including multiple tools for comparison.

Choosing a saber saw, be sure to consider the nature of the future work with it to correctly pick up the instrument in size and weight. To dismantle a shed or reinforced concrete wall, you will most likely need a powerful tool with comfortable handles for both hands. And the mass of the tool (3-4 kg) does not play a special role here. And if you are going to trim the branches of apple trees, standing on the stepladder, it makes sense to choose a saber saw as compact and easy (and of course, it is better with the battery) - such models such as, for example, Makita JR100DZ, Metabo ASE 10.8 0 or Bosch Keo which weigh 1-1.3 kg. The cost of such a saw will be 5-10 thousand rubles, and more severe and powerful networking, are cheaper, 3-5 thousand rubles.

Circular saws
Circular saw is used for accurate and long saws of wood and all types of materials based on it, and in the presence of special saws, the saws with ease cope with the sawing of plastic, non-ferrous metals, aluminum alloy profiles. This tool is applied at all stages of construction, ranging from sawing boards and ending with carpentry and furniture work.
Disk saw intercol DP-190 / 1600m
Circular saws differ in the diameter of the disk, which can be installed on the saw, as well as the diameter of the planting hole. There are saws with a working diameter of the disk, as a rule, from 120 to 250 mm and with the planting opening 16, 20, 22, 30, 32 mm. Some sizes are more common (for example, disks 165/20, 185/20, 210/30 mm), some less often. In any case, make sure that the discs of the desired size can be easily purchased at any time.

Disk saws give the highest accuracy when sawing wood. For construction work, it is perhaps one of the essential tools with which you can perform equity cuts, making the boards of the required width. With the longitudinal sawing of thick bars and login, high power of the instrument is necessary, so with a large amount of work it is not necessary to save on this characteristic. It is better to choose a model with a reserve in power (1,500-2,000 W), rather than burn the tool in the opening of the work. To work with thermoplastic plastics, it is desirable that in the circular sawing the number of revolutions is provided (thermoplastic materials are cut at low speed).
Disk saw blades ZPD-2000
Disks are available for different types of wood, and also designed for coarse or accurate work. The diameter of the disk determines the maximum depth of propyl, which is about 30-40% of its magnitude. It is necessary to choose the tool so that the maximum depth of punched has been sufficient for cutting thick boards. Therefore, let's say, the saws with a diameter of a disk 130 mm and the depth of 52 mm was not suitable for cutting board-fifty (50 mm). On the other hand, such models are very convenient for work due to their compactness and a small weight (the mass of such a saw can be 2.5 kg, and the mass of saws with a disk of 210 mm - turn out to be more than 5 kg). Perhaps, with a large amount of work, it makes sense to arm yourself with two models of circular saws with large and small working diameters of the disks. The benefit of the cost of circular saws is not very large: for 4-5 thousand rubles. You can purchase a tool full of decent quality.For cutting boards with great accuracy, removable guides are used, which in some models included in the package saw, and sometimes purchased separately. With a large amount of such works, it makes sense to purchase a sawing machine, the benefit can now find models for quite affordable money. Thus, models of Machines "Interskol", Ryobi, Bosch, Einhell can be purchased for 10-25 thousand rubles.
Chain saws
The chain saw is characterized by the highest performance and is used for coarse sawing wood, if you, for example, you need to sow a tree or cut it on firewood. With a well-known experience (and the availability of appropriate devices, such as carriages for cutting a tree trunk on the board), a chain saw can also be performed more subtle operations, cut bars and boards with high accuracy.
Chain saws are well suited for rough cutting wood.
Choose a saw with comfortable handles for comfortable work.

Some saws provide maximum speed, but they give the quality of the cutting. These are primarily chain saws. The most important characteristics are the speed of cutting and safety, and, of course, the price. The saws are available with chains with 1/4, 0.325, 3/8 incidence, 0.404 inches. Household saws usually equipped with chains with a small step, they are cheaper, and the tool is easier to hold. Also, chain saws differ along the bus length (in household models it is usually from 25 to 45 cm). The shorter tire, the tool is more compact and less weighs, but, accordingly, its potential performance is reduced.

Chain saws, in contrast, let's say, from circular, need regular service. They must be filled with oil so that it is constantly in the instrument: when working, the dry saw can overheat and fail. In addition, it is necessary to regularly rule the chain teeth using a special round file. Therefore, when buying a chain saw, it is better to immediately buy the desired oil and the tool.
Professionals are recommended to rule the chain teeth saw at each filling of saws with oil, but in domestic conditions it can be done and less often, once in two or three refills.

Alligators saws
The saw-alligator is an interesting type of tool with a reciprocating mechanism. It uses two cutting canvas moving in a support bus on the opposite to each other.

Thanks to this, the tool works easily, without jerks and vibrations, characteristic, say, a saber saw, the sole of which needs to be tightly pressed to the surface treated. The saw-alligator - the tool is quite powerful and productive, in a circle of tasks it is close to the saber saws.
Alligators saws are used to cut a wide variety of materials.
Long tire allows you to cut thick brices.
Lobziki
Choosing a jigsaw, pay attention to the design of its enclosure and especially the soles. It is desirable that it be designed to exclude its deformation at intensive work (a slightly curved guide leads to a marriage when working). Well, for example, if the sole of cast aluminum alloy with ribbon ribs. The body of the tool must be balanced so that it can be kept on the weight with one hand, without applying forces. The handle of the electric jigsaw can be two species - closed and open. The most versatile is considered a closed handle. At the same time, the jigsaws with an open handle are considered to be more adapted to curly drinking.

The main technical characteristic of the electrolovikov is the number of pink strokes per minute. The greater the number of "stitches", the higher the speed of work. In most modern models, there is an ability to adjust the speed (in the same way as it is provided for in the adjustment of the shuttle speed of the electrical sewing machine). For not too an experienced user, it is better to choose a low or average speed of work (1,000-2,000 strokes per minute). In many jigsaws there is a mechanism of pendulum stroke (the Pilka makes not only progressive movements forward-back, but also oscillatory, like a pendulum). This mode of operation increases the performance several times, but reduces the quality of the cut, so it is good to use it for rough work.

Lobsiki as a whole belong to relatively inexpensive tools. For 3-5 thousand rubles. You can purchase models of such well-known manufacturers like Bosch, Makita, Metabo, Ryobi, Interskol. Most of the modern jigsaws are used with a T-shaped shank, their other options are rare (and it is better not to choose such a tool so that there is no problem later when searching for the desired pylons). Pilking are produced for different materials (solid and soft wood, metal, plastic, etc.), so choose a pink according to the type of material and the nature of the work.
The design of the handle and a good overview of the place of the cut is important with curly drinking.

Advantages of battery tools
Rechargeable models today are present in almost all types of power tools, including in such categories that were previously considered not too suitable for batteries, for example, in circular saws (this, for example, model Ryobi R18CS-0, Makita HS301DZ, Bosch Universalcirc 12 0, Greenworks G24CS 0) or, say, chain saws (GreenWorks G40CS30, DeWalt DCM565P1, Husqvarna 120i). This happened due to modern battery models that are able to provide work in any intensity mode, especially if you have a spare battery. Their high cost is the main disadvantage (several thousand rubles per piece). And the rest of the battery equipment is much more convenient: it is more compact, easier and much quieter, if you compare with MODEL models). And, of course, no one is with feed cables.
Increased battery capacity allows avoiding downtime even with intensive work.

The jigscription is poorly suitable for finishing cutting, usually then the edge of the cut is milling or grinding. This is due to the fact that the movement of the peel is not allowed, especially by such inhomogeneous material, like wood, due to the fact that the saw is thin and console. In this case, any inhomogeneity in the wood causes a rejection of the peel. An experienced operator compensates for him, but small oscillations still remain. If you need to get as smooth cut as possible, choose the peer with the greatest divorce of teeth (usually it is the pinks for a coarse cut, the body of the canvas milled on the wedge), set the maximum number of double strokes, be sure to disconnect the pendulum and saw slowly, With minimal feed feed.
