Jigsaw type saws
It is also important to understand how to choose the right jigsaw unit. It is recommended to consider numerous characteristics for a successful selection
The thickness of the workpieces to be processed. Even small models can handle 50mm wood. Stronger and larger jigsaws handle 100mm wood.
Jigsaw table. The work table can be made of cast or extruded metal, but it must be reliable and level
In addition, it is important to consider the possibility of adjusting the position of the table.
Departure of the canvas. For small tables, the overhang will be about 380 millimeters, for large ones - 600.
Electric motor
It is necessary to take into account power, number of strokes per minute, speed. These indicators determine how successful the work with the saw will be.
Saw stroke length. It is necessary to take this indicator into account for the successful processing of wood in an upright position.
Tensioning the file. It is important to ensure that the tension is secure so that the structure retains its original quality when sawing.
Fencing of the canvas. Sometimes this part is optional. In other cases, the fence consists of 1-2 rods of wire or special plastic.
Clamping device. Its presence prevents vibration of the processed material and the movement of the wooden workpiece.

Jigsaw
A pendulum electric saw, better known as a jigsaw, has its own scope of use. This device is primarily intended for longitudinal, transverse and shape cutting of sheet material. Using cutting tools with different characteristics, you can work with the same success with boards, wood-based panels, plywood, laminate, thin sheet metal.
The cutting part of the jigsaw is a nail file, which is fixed at one end in a retainer, which performs reciprocating movements. Often, the vibrations of the cutting tool are not limited to the vertical plane, but are complemented by a pendulum motion, this provides a high speed of work and increases the service life of the blade.
In addition to regular (straight) cutting, many models provide the ability to cut the workpiece at a precisely specified angle. For this, the support table is rotated and fixed. This function significantly increases the scope of the jigsaw. A common household tool allows you to cut at an angle of up to 45 degrees.
Basic saw models Metabo
The manufacturer produces a wide variety of power saw options. They differ from each other in many ways. For home use, the most convenient is a circular saw. It is based on the work of the cutting disc from the engine. In turn, circular saws are presented as static models, and portable, equipped with a comfortable handle.
Portable models include assembly (pendulum) saws that facilitate sawing metal at different angles. For example, to make a metal blank. For those who have decided to purchase a construction assembly saw, the company offers a cut-off model CS 23-355 SET. This model is designed for fast and efficient cutting of pipes and profiles made of hard metals (aluminum, steel and other materials). In order to easily replace the wheel, the saw is equipped with a spindle lock.Ease of operation provides a device that gently adjusts the cutting angle.
This device is equipped with a powerful 2300 W motor with no load speed of 4000 rpm, an adjustable cutting depth stop, and an ergonomic built-in handle for transporting the device.
Hand-held circular saws are in great demand. They are very easy to use and carry. The assortment of this type of tool is represented by a large number of models. Let's name two of them that are the most relevant today.
- Hand-held circular saw KS 55 FS. It is distinguished by its durability and good power of 1200 W and the no-load speed of 5600 / min. An anti-slip grip on the handle and an aluminum guide plate are available. Product weight is 4 kg, cable length is 4 meters.
- Cordless hand-held circular saw KS 18 LTX 57. Power supply unit - 18 V. Speed of the disc without load - 4600 / min. It is a versatile building model with a non-slip handle. The cut indicator has good visibility. Weight with power supply - 3.7 kg.
Another multi-cut tool for cutting wood and metal is the band saw, which has its advantages over the rest. It is like a modernized jigsaw. The convenience of this device is that the material can be held with two hands, which allows you to more accurately cut it at different angles.
The band saw can handle fairly thick workpieces, since the cutting depth is between 10 and 50 cm.
On the building materials market, Metabo presents many models of band saws.
- The band saw from the Metabo MBS 18 LTX 2.5 battery. Designed for precise cutting. Serves for cutting hard metals into workpieces of small thickness. The convenient mechanism allows you to work in places with difficult access, as well as overhead. Low vibration and non-slip grip pads, as well as built-in illumination allow precise cutting operations. The power supply shows the charging level. The weight of such a product with a battery is only 4.1 kg.
- Band saw BAS 505 PRECISION DNB. Two cutting speeds available for different purposes and materials. The high cut quality ensures good stability and precision. The motor power is 1900 W with a cutting speed of 430/1200 m / min. The weight of the product is 133 kg, which makes it rather problematic during transportation. However, such a power tool will be an excellent assistant in a stationary workshop.
Every year more and more improved models of electric saws are produced, and the manufacturer Metabo is one of the few who does this regularly. Today anyone can buy such a tool.

Tips for choosing a power saw
To make the right purchase of an electric saw, you should familiarize yourself with the criteria for its selection in advance. First you need to know the purpose for which this tool is being purchased.
The same applies to dimensions - specialists may prefer large-sized models, but for work at home, it would be right to purchase a saw of a small size and weight for easy transportation.
In the store, it is best to try on the tool for yourself, so that it is comfortable to work with it. The size of the disc is also important - its diameter should be at least 200–250 millimeters (the larger the better). The depth and width of the cut determine what materials can be processed with a given tool.
One of these models is the KS 216 M LASERCUT miter saw with a power of 1200 watts. The light weight of 9.4 kilograms makes it easy to transport. There is a laser and a built-in flashlight to illuminate the cutting area. The unit is powered by the mains. A special clamp fixes the workpiece well during operation.
The popularity of the goods of the German manufacturer Metabo led to the appearance on the market of its fakes. In order not to become a victim of buying a low-quality tool, you need to know several features that distinguish the original from a fake. First of all, these include the original packaging, a package of Russian-language documents, all kinds of quality and safety certificates, as well as warranty coupons.
External signs are no less important - the accuracy of the painting of the case, the evenness of the logo application, as well as the quality of the metal from which the case is made, it must be durable and without gaps. The price aspect is also important. Too low a price speaks of one hundred percent fake. You can find out the price on the website of the official representatives of this brand in Russia.
Varieties and their purpose
Today, foreign and domestic manufacturers present a number of high-quality cordless hacksaws. They, in turn, are:
- circular;
- jigsaw;
- chain;
- saber;
- for cutting glass / ceramic tiles.
However, equipment of this type cannot be called multifunctional - a working saw from the network still has more capabilities, copes with more complex tasks, for example, processing coarse materials. Nevertheless, domestic craftsmen fell in love with battery units - they are mainly used at the final stages of repairs, for finishing work.
A circular (aka circular) saw is designed for longitudinal cutting of wood, derived from it materials: chipboard, fiberboard, OSB, MDF, plywood. Compared to a jigsaw, a saw for wood perfectly keeps the line during the cut, performs high-quality cross-cutting. The circular saw has one more feature - using different types of discs, the shaft rotation frequency changes, in this regard, the hacksaw will be able to cut even plastic, slate, gypsum fiber sheet, plexiglass, and other multilayer materials.
The circular saw handles various sheet panels by cutting the surface at an angle. However, such a hacksaw cannot afford dense raw materials, namely plaster, concrete, brick. Modern construction tools include an optional diamond blade as well as a state-of-the-art water supply function. The only drawback of a circular saw is the inability to cut along a curved line.
Jigsaw is one of the most popular units of the type of grinder, hammer drill, screwdriver. Differs in ease of use. It is mainly used for curly / straight cutting of the following materials: plywood, gypsum fiber board, gypsum board, MDF, OSB, chipboard, plexiglass, thin cement tiles.
When laying a roof or timber frames, the saw will easily cope with a massive bar (albeit in two passes), it will easily cut the board. By the way, in this case there is no need to go through with the saw. It will not be difficult to process laminate, parquet, wall paneling, and other similar materials. In the process of tiling, a jigsaw demonstrates curved trimming (this type is used to bypass a column or communications).
Rechargeable saber - improved hand hacksaw. Manufacturers have endowed it with versatility, so it can be safely called universal. It perfectly demonstrates its qualities in the work of a plumber, roofer, finisher, carpenter. The saw easily, evenly cuts wood, steel, non-ferrous metal, various metal elements, stone, plastic, foam block, ceramic products, glass, composite.
The effectiveness of the action is ensured in the case of the correct choice of the blade. This device is equipped with a good longitudinal layout, and the reducer is stretched out. It is with the help of a long blade that the tool is able to operate in rather narrow spaces.
A reciprocating saw will easily cut off beams, pipes that even a jigsaw / angle grinder cannot handle.It is worth noting the possibility of the functioning of this hacksaw by weight, as well as for the preparation of parts: corners, pipes, bars, boards.
Chain - cordless hacksaw designed for gardening, summer cottage work. Able to cope with light loads, for example, sawing logs with a diameter of 10 cm. Battery power - 36 V. The charged device provides fairly long work without additional recharging.
A garden saw in its functionality is similar to brush cutters, trimmers, lawn mowers, therefore it is sometimes used together, especially in the country. It is this feature that reduces the cost of the chain-type electric saw.
When choosing an electrical appliance, be guided by the raw materials with which you have to work. Domestic and foreign manufacturers of equipment offer models of hacksaws for metal, wood, for trimming. Versatile views can handle multiple types of surfaces at once. True, the price for such a unit will be higher. In any case, choose what is of better quality - such a tool will last a long time and will delight you with the result.
In the next video, you will find an overview of the Bosch KEO cordless hacksaw.
How to choose a reciprocating saw professional advice
To choose the right reciprocating saw, you need to pay attention to the following points:
Power. Power determines all other parameters of the device
This is a key characteristic. It should be powerful enough to work with the materials and thicknesses of your choice. In principle, the higher the power, the higher the productivity, the depth of cut, the wider the range of available materials and thicknesses, the longer the continuous work time and resource. However, it should be remembered that a device that is too powerful for occasional home use will also have a lot of weight, dimensions and power consumption, and most importantly, a high price.
Speed regulation. Stroke frequency control is present in the most budget models. If you plan to cut one type of material, then you can get by with the simplest adjustment - according to the degree of pressing the power button. If a frequent change of material and its thickness is expected, then it is better to consider devices with two-stage adjustment: limiting the maximum frequency with a slide or rotary switch and a set of revolutions with the power button, but not more than the limit set on the switch.
Pendulum stroke. The pendulum stroke is designed to speed up cutting and increase the blade resource. If you have a lot of work ahead of you, this is a must-have option. If you plan to cut out extremely complex curved contours from a relatively thin sheet, then the pendulum motion will be superfluous, it will still have to be turned off.
Support shoe. The support shoe should be. It increases the convenience and safety of working with a reciprocating saw. If you plan to saw objects of complex shapes in hard-to-reach places, then it is better to choose a shoe with several degrees of adjustment - reach, tilt, turn.
Blades replacement system. On modern models, a system of quick replacement of canvases is used. Different manufacturers promote their own designs, but all of them must provide one-handed blade replacement, and preferably without removing gloves. High-quality models ensure that the stem stops in the extreme extended position; on budget models, you need to be prepared for the fact that you have to turn the saw on and off several times before you can catch the position to change the saw. The blade cannot be pulled out by hand.
Smooth start. The soft start system must be installed on powerful devices. This will protect the mains power supply from current surges, and will also ensure an accurate start of the cut. If the operator does not have great physical strength or experience, it is better to consider such a system for household-class devices.
Cutting depth. The cutting depth is related to the engine power. This parameter determines how thick the material you can cut.If the vending reciprocating saw does not cope with those boards, beams or sheet material with which you plan to work, you will have to choose a more powerful one.
Ease of use
It is very important that the device lies comfortably in the hands, the power cord does not interfere with the work, the weight of the device should not tire the operator's hands. Some craftsmen, before buying, rent several different models in order to evaluate the usability in practice and buy the most suitable one.
Type of food
The rechargeable type of power supply is best chosen if you plan to use the device outside the home, in the garden or on a construction site where there is no constant power supply. The rechargeable device is also handy when you need to do small amounts of work in different places on the construction site - then you save time dragging and dropping extension cords and reconnecting cables. The mains type of power supply is more convenient if many operations are performed close to each other, and the amount of work is large, for example, in a carpentry workshop. In this case, time will be lost just on recharging the battery. The mains supply is also convenient when a constant cutting speed is required - for cordless machines, as the battery is discharged, the power decreases.
