Electric circular saw overview
The design is unified, there is little difference between different manufacturers:
- Frame. It contains work items;
- Electrical engine. Responsible for power;
- Reducer. Transmits torque from the electric motor to the saw blade;
- Saw blade. Replaceable module, selected based on the material for processing;
- Protective cover. Located above the saw blade, protects the operator from splinters and blade breakage;
- Steel base. A flat platform designed to obtain a straight cut line;
- Riving knife. Located behind the saw blade. Performs protective functions.
2 Which saw to choose?
The main difference between professional and consumer models is their power: the former are equipped with a stronger motor, which allows them to use larger diameter discs and, as a result, cut the material deeper. In addition, the motor of a professional tool is able to work without interruption for a long time, and it is recommended to turn off household saws periodically to cool down.
If you plan to carry out regular construction work, you should give preference to professional models. And it is more expedient to purchase a household tool if it will be used from time to time for small operations.
The difference between handheld and tabletop (stationary) models lies not only in their design, but also in their power. Usually, this indicator for the latter is much higher than that of a hand tool. The tabletop version is optimal if you have a home workshop, in which it is possible to equip a separate workbench for working with the saw. A manual circular is also suitable for single work, especially since many manufacturers offer special devices with which the tool is fixed on the tabletop in an inverted position.
Popular models
A distinctive feature of Hitachi circular saws is that they can work not only with wood, but also with plastics, copper, aluminum and other metals. It is only necessary to choose a model that will differ in the given characteristics.
C6SS
This device has been designed for industrial design. The main advantage of the model is its excellent traction properties, which favorably distinguishes it from its competitors. Hitachi C6SS delivers high performance with a 1050 watt electric powertrain. The cutting depth when using this unit can reach 57 mm due to the fact that the blade diameter is 165 mm. Among the advantages of this model, it is possible to note its ability to rebuild in a short period of time to perform various types of cuts.
C6U2
Hitachi C6U2 is one of the most popular models, which is equipped with a powerful 1100 watt power unit. This is quite enough for the device to cope without problems with wood materials, the thickness of which is 54 mm. The presence of additional attachments allows you to make not only straight, but also corner cuts. The surface of the Hitachi C6U2 model is finished with chrome, which provides reliability and resistance to corrosion.
C7SS-NA
This model is one of the lightest in the range of Hitachi. Despite the fact that Hitachi C7SS-NA is a representative of the budget segment, it is equipped with a 1050 W power plant. Thanks to this, the blade can accelerate to 5500 rpm. With its low weight, the tool boasts the presence of an additional handle designed to simplify the operation process, as well as several protective covers.
C7MFA
Hitachi C7MFA is a semi-professional device that can be used not only in a domestic environment. Unlike previous versions, this model has been significantly improved, as a result of which its reliability and ability to cope with high loads have been increased. An upgraded 1050 W power unit is installed here.
C9U3
Hitachi C9U3 is a professional model with a large mass and a powerful power unit. The equipment received a motor with a power of 2000 W, thanks to which the disc blade boasts a diameter of 235 mm. A distinctive feature of the device is the presence of an innovative electric brake, designed to ensure high reliability and safety.
Service
Of course, this is only a small part of the quality models on the market today. Finding the perfect power tool is an eternal search for a compromise between power, workmanship, reliability, availability of additional options and the price of the device.
It is important to remember that hand-held circulars saws for wood are high-precision electrical appliances that require proper care and maintenance. Protect the device from moisture, especially network models
Cordless saws can be used in damp rooms, but not outdoors during precipitation. Over time, it may be necessary to clean the housing from accumulated sawdust, which worsen the cooling of the engine, as well as to lubricate the mechanical parts of the gearbox. Consistent substances like "Solidol" are well suited for this.
Do you use a circular saw?
Constantly! I want to try
Before each new use, sawdust, tar and other contaminants are removed from the working surface of the disc with liquid reagents, then wiped dry with a clean cloth.
Discs should be replaced immediately after the first signs of damage to the teeth are detected - if you continue to work with a faulty disk, you can not only spoil the cut, but also get serious injury.
It is permissible to sharpen dull teeth, but if you do not have experience with a sharpening tool, it is better to entrust it to a professional.

- power and number of revolutions, which is performed by the cutting part of the machine;
- cost and completeness of a specific model.
In order to eliminate the risk of overloading the electric motor when using the tool, it is necessary that an emergency shutdown mechanism is present in the saw structure. Experts advise making a choice in favor of a model that has a smooth start. In this case, jerks are completely excluded when the cut is being formed.
When performing an operation on inclined sawing, specialists may encounter such a phenomenon when the depth of processing does not at all correspond to the indications given on the adjustable scale. In such a situation, it is necessary to correct the value, for which you should use the recommendations contained in the instructions for use of the tool.
Conventional circular saws have been used to cut workpieces for many years. With all the advantages of this tool, it had one significant drawback - the low quality of the cut.

Circular Sawing Machine
To complete the picture, it is necessary to mention one more tool, which is a must in any carpentry workshop. This is a circular saw.
It can have a different design, but in all cases it is a stationary tool, completely unsuitable for transportation from place to place. As a rule, it is equipped with a fairly powerful electric motor and a large diameter saw blade. This enables it to quickly cut even thick workpieces.
The large working platform and the infinitely variable height and tilt of the saw blade enable high precision ripping of workpieces.
