To date, manual circular is found in all construction markets. Such equipment is represented not only by domestic brands, but also by foreign ones, especially Chinese manufacturers. All of them differ not only in technical characteristics, but also in price. Therefore, it is necessary to choose the right mechanical saw to cope with the tasks.
General information
The circular hand is an indispensable tool in performing not only domestic but also production tasks associated with sawing building elements from wood.
In addition, by putting special discs, you can saw slate, metal, plastic, etc.
Device and principle of operation
Before you buy a hand saw, you need to understand its design and principle of operation. This information will help to make the right choice. The circular hand has many types, but the principle of their action is no different from each other. The electric motor is turned on, and rotational movements are transmitted to the disk, with the help of which various types of building materials are sawed. To work with each material you need a special canvas.
Mini circular consists of the following structural elements:
- engine;
- special case with handles and control buttons;
- cutting disc;
- protective construction;
- ventilation system;
- platform guiding the movement of the cutting element.
As a rule, a mini-circular has an engine in its configuration, the maximum power value of which reaches 2500 watts. This technical characteristic is the key, and therefore it is worth paying attention to it.
As a power source is a regular consumer electricity network with a voltage of 220 V or a battery. Thanks to this circular it can be used at different construction sites and places where it is impossible to connect to the network. The battery can be either built-in or remote.
Another major element is the circular disk. In the modern construction market, you can purchase canvases that can cut any building material. They differ in size and number of teeth.
To change the cutting depth, a guide pad is provided in the design. It is made of metal or aluminum. The first type is characterized by low quality work. Therefore, for more precise cutting, an aluminum guide pad should be used.
Which is better to choose: domestic or professional?
Like many construction tools, a hand circular is of two types: household and professional. The main difference between them is that when working with household models it is necessary to take small breaks to cool the electric motor.
If this is not done, then it can burn out. In a month, a household saw should work no more than 30 hours. If it becomes necessary to carry out various work not only at home, but also at other facilities, it is best to purchase a professional model. Compared with the household version, such a saw can work continuously for 50 minutes. Of course, its cost is much higher, but the quality and reliability are at a high level.
Key Specifications
Before you buy a circular saw, you should pay attention to its technical characteristics.
First of all, pay attention to the following parameters:
1. Power. This figure depends on the diameter of the discs used. The larger the indicator, the larger the diameter of the working blade. A high power indicator indicates enhanced operational properties. But do not pay much attention to this parameter. As a rule, powerful models are characterized by high cost and weight. For example, a manual circular with a power of 1400 watts has a weight of 4 kg.
2. The frequency of rotation of the disk cloth. The larger this indicator, the faster the material will be sawed. In this case, the quality will not suffer. Therefore, to obtain high-quality sawing, you need to purchase a hand saw with high speeds. In addition, the frequency can be adjusted manually. This parameter is different for a particular material.
3. The depth of cut. This indicator depends on engine power. Depending on the complexity, this value is:
- for domestic purposes - 40 mm;
- for semi-professional purposes - 50 mm;
- for professional tasks - more than 70 mm.
4. Corner cut. Modern models of hand-held circular saws perform cutting at an angle of 45 °. But there are brands where the angle is 60 °.
additional characteristics
Wood circulars also have additional characteristics that are aimed at improving operational properties, as well as simplifying the cutting process.
These characteristics include:
- Regulation of the speed of rotation of the working blade. It consists in selecting the necessary speed for cutting a certain type of material.
- The process drank. Thanks to this characteristic, work can begin on either side of the product.
- Smooth start. This property ensures a long service life of the equipment.
- Built-in backlight and layout. Designed for more precise cutting.
Makita circular saw
Makita hand-held devices can be both domestic and professional. They are used for sawing wooden products at home and on large construction sites. The Makita circular saw is capable of many tasks thanks to its powerful technical features. As a working cloth, disks of different diameters are used. The angle of cut is 45 °.
This type of saw meets all safety requirements. In addition, a special inrush current function is provided in the design. With it, work is carried out more smoothly. It is suitable for both amateurs and professionals.
You can buy it at any hardware store.
Bosch: Features and Benefits
The Bosch circular saw entered the world in 2009 and has since been an indispensable tool not only for professionals, but also for beginners. Its main advantages are high power, as well as an increased rate of cut, which is 56 °. In addition, for ease of operation, the device has compact dimensions and low weight.
The work process has become much more convenient, since the line of sight is longer than other models.
Another advantage is the integrated chip blowing function. It is carried out with the help of a powerful air stream, making the working surface clean. The German Bosch circular saw has a high degree of safety. If a dangerous situation arises, the working disk can be easily stopped thanks to a convenient switch located on the case. You can do this with either hand. The protective cover is made of stamped metal, which withstands harsh operating conditions.
Circulars: reviews
Many users are pleased with the work of hand-held circular saws. They are designed for various materials both at home and at the construction site.
When choosing equipment, you should pay attention to power. This indicator is the key. After all, the rotation frequency of the working blade and the depth of cutting depend on it. The cost of the tool depends primarily on the type, that is, whether the equipment will be used in everyday life or in production, as well as power. The price for household models ranges from 2.5 to 7 thousand rubles, and for professional ones - from 15 to 40 thousand rubles. Also, users note a high level of security and reliability. In the event of dangerous situations, the saw can be quickly turned off using a special button. Moreover, the torque of the disk will be absent.
So, we found out what are circular saws.
