This rating of metal mounting saws for 2020-2021 was made according to the estimates of specialists who work with such tools. There is no accounting for the number of sales or any abstract indicators from research centers, which for some reason are trusted the most. Probably, many gentlemen with academic degrees will call such an analysis amateurishness, but they don’t work with these saws.

Brief information
Based on statistics and customer reviews, this article has compiled a list of the best mounting saws, as well as their manufacturers, which are characterized by wide demand among professional users. The cutting tool must be highly reliable and durable, since working with a saw is considered a dangerous activity. That is why the rating includes manufacturers who carefully approach the issue of developing safe and effective saws. Among these you can find Metabo, DWT, Sturm - these are developers producing professional tools. It is worth paying attention to the fact that Switzerland occupies a leading position in the world market, since manufacturers in this country produce the best equipment and always receive rave reviews from customers.
In addition to professional tools, the rating includes assembly saws, which are more related to household use. Such a tool is characterized by lower power and, naturally, cost, but it is often used during light construction work. Responsible for the production of such equipment are: Ryobi, Odwerk, DeWalt. The companies AEG, Makita and Armateh are developing budget mounting saws - the tools of these manufacturers are designed for performing small jobs. Before choosing a saw, you should decide on the type of work, expected loads and characteristics of the tool. By correctly comparing these factors, the purchased tool will bring maximum effect.
High-quality mounting saws from a budget manufacturer cost from 5 to 35 thousand rubles. If the consumer needs a more reliable and efficient model, then you should count on an amount in the range of 50,000 rubles. Before reading the rating, it is worth considering which saws are considered the best option: DWT SDS 2200, Sturm CF7324 and Metabo CS 23-355. Their main advantage is considered to be the ideal ratio of quality and price.
Which mounting saw is better to choose?
When choosing a power tool for cutting metal, it is necessary to evaluate the build quality of the most important components, the materials used in the manufacture of parts and the convenience of the entire design for long-term operation. Let's look at what basic elements of the machine and its functionality you need to pay attention to.
What you need to know about engine types
Metal saws are equipped with two main types of electric power units.
Asynchronous motor
The asynchronous electric motor is most widely used in modern technology. It is reliable, relatively easy to manufacture, and has a long service life. It has a low starting torque and significant current during acceleration. It should be started at idle speed, after which it can be subjected to work loads. The absence of carbon brushes in the design guarantees long-term maintenance-free operation of the engine.

Brushed motor
Commutator motors incorporate graphite brushes that transmit current to the windings of a rotating rotor. Such models are usually smaller in size, easy to manufacture and repair, and inexpensive. They have limited power, low efficiency and require more frequent maintenance. They are not designed for long-term operation at high speeds. When choosing a machine with an electric motor of this type, it is advisable to make sure that you can replace the brushes yourself, so as not to resort to the services of after-sales services.

What types of drive can be used
The transmission of torque from the electric motor to the cutting heads of mounting saws is realized in two ways.
Belt drive
Belt drive is more typical for professional high-performance machines. It may cause a slight loss of power, but it protects the engine from overloads. The presence of several pulleys allows you to change the cutting speed mode and use discs of different diameters.

Drive via gearbox
Drive through a gearbox is more common in household and semi-professional tools. The gearbox transmits power without losses, but increases the load on the engine if the material resistance increases excessively. This negatively affects the service life of the entire machine.

What you need to know about power
Engine power is directly related to the technical capabilities of the metal mounting saw. The vast majority of models are equipped with motors consuming from 700 to 2600 W. This indicator is selected depending on the intensity of use and the nature of the operations performed. Leading manufacturers equip their products with overload protection and electronic speed stabilization systems that improve performance under high loads.
Type of disk used
When cutting and processing metal workpieces, you can use discs of various designs and materials. There are two main types of consumables used in mounting saws.
Abrasive discs
Abrasive discs are made from solid components and have internal reinforcement. During operation, they gradually wear out, which does not greatly affect the cutting efficiency, but reduces the possibilities for cutting volumetric parts. Their life cycle amounts to several dozen cuts.

They are prone to displacement and slight changes in shape, and this is a significant drawback with increased requirements for cutting accuracy. Such wheels are better suited for processing materials with high hardness, but wood, plastic or non-ferrous metals are difficult to cut.
Scope of application
A metal saw is one of the power tools that are often used in production. Due to the fact that the tool has high performance, it is used for cross cutting of metal products.
Assembly saws for metal are used in metalworking plants. This type of tool is also often found in factories producing various metal products. However, power tools are often used at home.
