Saw circular circular: overview, types, specifications and reviews

A hand-held construction tool has long been associated with just one hammer and screwdriver. Today, these are high-power and functional devices capable of performing complex tasks in difficult conditions. For more than a year, the interested consumer has been able to observe the development of the segment of compact circular saws, which are endowed with productive power engines, robust housings and ergonomic handles.

If before the vast majority of such tools were oriented to a network connection to the power source, now the circular battery was included in the assortment of almost every major manufacturer. Another thing is that each firm has its own approach to the execution of the instrument, although similarities in characteristics are not uncommon.

Features of cordless circular saws

The basis of the design is the same stuffing as in the case of traditional network models - a robust case with rubberized elements hides the engine, and the disk is responsible for the cutting function. The main difference is the unit with the battery element. Thanks to this component, cordless circular circular saws make it possible to perform work operations away from the socket.

Increased mobility is achieved due to the capacity of the charger, which may have different characteristics depending on the manufacturer. For example, the company "Bosch" in the latest models seeks to minimize the so-called memory effect. This means that, for example, the Bosch cordless circular saw of the GKS series, even after a long operation, will be able to provide the same duration of operation on one charge as in the first days.

Main characteristics of the instrument

Begin the review of technical and operational indicators is the battery. As a rule, manufacturers complete the saws with lithium-ion cells with a voltage of 10.8. The representatives of this line include a portable circular saw Makita battery in the performance HS300DZ. With average voltage indicators, the model demonstrates good performance with a frequency of 1400 rpm. On the other hand, the Milwaukee in the HD28 CS version has a battery capacity of 28 V, which allows it to provide more than 4000 rpm.

The next important indicator of the working capacity of the instrument is the diameter of the disk. Here, too, the weak side of models with batteries is shown. The fact is that technologists do not recommend completing devices of this type with large cutting elements. For this reason, the circular circular saw provides a modest cut, limited to a circle diameter of 184 millimeters. But in terms of performing complex cuts there are no special barriers - the movable sole of the tool allows cutting at an angle of up to 50 °.

Varieties of models

It is possible to distinguish several features, according to which battery hand-held circulars are classified. Among the main ones, the sphere of application is called, that is, the target material with which the tool can work. Most models are oriented to wood processing. At the same time, even more often manufacturers' lines are replenished with modifications designed for aluminum and mild steel. This includes a battery circular saw for metal from Milwaukee HD18 MS. This is a high-speed tool, which makes it easy to handle foam insulation panels. A similar option is offered by DeWALT in the eight-wave version of DW934K2.

Another sign of the separation of circular saws with batteries is the type of battery. Until recently, nickel elements have enjoyed a certain popularity, but lithium-ionic analogs are more practical in the process of operation. However, in favor of the former, their ecological safety speaks.

Product Reviews «Makita»

In the line of the Japanese manufacturer, it is worth paying attention to the DSS610Z, which, in addition to the powerful Li-ion battery, also has several design additions. In particular, users note that the combination of a ruler with a parallel stop contributes to obtaining a high-quality cut. These adaptations correct the parameters of the working stroke, providing an accurate cut at the input. Otherwise, the owners' feedback is also positive. For example, it is noted that a cordless circular saw "Makita" can be considered as an optimal option for beginners, since the tool has a high class of reliability and safety. This is due to the presence of an enhanced protective casing at the base of the disc, an electric brake with an instant stop of the disc, and a button fuse.

Product Reviews «Bosch»

The family of cordless circular saws of the German manufacturer represents the said modification of the GKS, operating on a lithium-ion battery. Owners of this tool indicate the accuracy of the cut, low noise and accuracy when performing cutting. That is, the machine does not scatter sawdust due to the possibility of their instant assembly in the dust receptacle. Also, users note compatibility with the ruler.

Actually, you can purchase this option even as a basis for making cuts - then the design is easily supplemented with the necessary devices from the same line with screwdrivers to a construction vacuum cleaner for the assembly of sawdust. At the same time, the circular saw Bosch GKS 10,8 is not devoid of shortcomings. According to users, the manufacturer has significantly limited the choice of working disks, among which, for example, there is no element for cutting aluminum.

Comments about Ryobi model

The manufacturer Ryobi is not as well known as the aforementioned brands, but in this case it was able to surprise even experienced builders with a successful development in the form of a cordless circular saw R18CS-0. Apparatus first liked the owners the ability to perform a neat and clean cut. Thanks to GripZone coating, the handle also provides a good grip of the hands with the structure, which facilitates the manipulation of the tool during operation. At the same time, there is a low power, which is provided with a cordless circular saw. Reviews, for example, do not recommend this option as a full-fledged replacement for network analogs. The tool provides quality propyl with quiet operation and generally decent ergonomics, however for serious work in production this model is unlikely to fit.

Feedback on the Metabo tool

In its characteristics, the KSA 18 LTX fits perfectly into the group of medium hand-held circulars with batteries. However, in places the tool features also appear. For example, many builders note that this version is one of the best for performing a slanting cut. Thanks to the original design, the operator can easily perform corner cuts. Separate attention deserves and ergonomics. We can say that this is a rechargeable mini circular saw, since its mass does not exceed five kilograms. But the number of revolutions exceeds even the initial level - 2700 rpm. In terms of configuration and additional equipment, the model is also not inferior to advanced developments. Already in the basic version, the tool can be retrofitted with a ruler, a parallel stop and a vacuum cleaner.

What to consider when choosing?

The battery principle of energy supply does not exclude the addition of the tool with new functionality and operational capabilities. When choosing a circular saw, it is recommended to consider such options as LED lighting, battery indicators, the possibility of combining with other construction equipment. For example, firms "Bosch" and "Makita" recommend to supplement the tool with their own industrial vacuum cleaners, which suck in garbage right in the process of work. Also, a circular circular battery should meet the safety requirements. Especially for beginners it is important to take into account the protective qualities of the case and the availability of protection systems.

Instead of concluding

Circular saws in the segment of hand tools of this type benefit from compact dimensions and ease of handling. In addition, the very principle of battery power supply gives many advantages over network analogs. This is the reason for the popularity of this product. The tool can be used on construction sites that do not have access to electricity. On the other hand, a circular circular battery, unlike traditional network models, requires a limited amount of time. Therefore, in addition to the parameters of the cutting blade, structural additions and ergonomics, it is important to take into account the characteristics of the feed unit. Experienced masters recommend paying attention to the ability of the element to maintain stable operation as energy is consumed. It will not be superfluous and the presence of a panel with a charge indicator, which during the operation of the saw will allow monitoring the level of the current potential of its battery.
