If the building a house or bath it is necessary to make a direct propyl to a certain depth, help hand-held circular saw. Model selection depends on many factors and nuances of future exploitation. We offer to meet with the principle of operation of this power tool, its advantages, disadvantages, as well as popular models, deserves your attention.

Application area

Hand-held circular saw is used when performing construction work. She is also in demand in the home and in small workshops. The disc moves in the longitudinal or in the transverse direction in a straight line. Used for cutting wood in size boards, From a soft metal, plastics and slate. For concrete, brick and plaster the tool is not suitable.

Design and function hand-held circular saws

The design of all the hand-held circular saw is very similar. They contain:

1. Housing. Is 1-2 with handles.
2. Protective cover, which provides secure the machine's environment.
3. Platform that provides the correct position of the disc at the cutting board.
4. Riving knife. With it, you can free up disk stuck in the wood.
5. The electric motor that transmits the rotational motion to the disk.

The operating principle of this blade is based on the transmission torque from the engine to the drive shaft. Last, rotating at high speed, allowing to cut off part of the wooden boards or some other material. Cutting is performed only in a straight line. Cutting along the arc is impossible.

Basic specifications

The possibility of hand-held circular saw blade depend on its technical parameters. These should include:

• disk rotational speed;
• power device;
• circle diameter of the saw;
• electric cable length or capacity of the battery, if the choice is made in favor of a mobile circular saw;
• the direction and depth of cut.

Advantages and disadvantages

The main advantages of the circular saw should include:

The disadvantage is:

Hand circular saw: the choice depends on the tool requirements

Choose the right model is quite difficult. Not to be mistaken with the purchase, we offer to focus on a number of criteria, deserve attention. They will allow to select the manual saw circulation, ability to cope with the tasks.

power

Perhaps this is the most fundamental characteristic that determines the speed of rotation of the disk and the allowable depth of cut. In low-power models this option is about 0.8 kW. This tool is suitable to carry out repair work in the country and at home. Usually it is used from time to time.

The average class capacity reaches 1.2 kW. It can be used for continuous operation. More expensive low-power analogue, but by making a choice in his favor, you can perform various kinds of work in the process of building a house, arbours or any other object.

More powerful devices are professional. Products are heavy and are available stationary. Allow the installation of large-diameter disks. Allow to make deep enough propyl. But because of the cost, in the home is almost not used.

For speed

Frequency affects the quality of the cut, the precision and the ability to handle a particular material. The larger the figure, the above mentioned parameters. If you plan on processing the solid molded article, pick a manual circular saw with the greatest speed. However, if the planned processing plastic or other material with a low melting point, it is better to choose a model with a minimum of turns. Significant warming at the point of contact and disk products will lead to the melting of the latter.

By supporting the sole structure

Of the supporting sole affect the functionality and reliability of the instrument. Are stamped and cast milled. Last made of aluminum alloy. Have less weight. Formed from stamped sheet steel. They have greater rigidity. Retain the geometry at random bumps and dips. Detachable abutment portion provides a front longitudinal cutting lumber. Preferably its fixation in two places and the presence of the millimeter scale.

By adjusting the position of the disc

Opportunity to drive tilting significantly expands the functionality of manual circulation drank. Cutting may be performed obliquely. The angle varies in the range of 30-55º. With this feature the device capabilities expand considerably, and the cutting quality is improved.

According to the depth of cut

The depth of cut depends on the selected diameter of the disc. When choosing should focus on a maximum thickness of material being cut. There is a division between the main sizes. For everyday needs enough of 40-45 mm. Semi-professional models allow to perform propyl 50-55 mm. Professional - cut material 60-70 mm thick.

Attention! Some models allow you to adjust the depth of cut.

According to the type of food

Current models are able to operate on AC or battery. The latter option makes the manual circulation saw more mobile. The works can be carried out at a considerable distance from sockets. However, such devices have greater weight and limited battery life.

If you want continuous operation, the tool is preferably operated network. He will be able to function for a long time. However, in the process there may be some difficulties due to the limited length of the cord.

Ergonomics and quality of products

The ergonomics of the tool determines the ease of operation. It depends on the personal preferences of the master. Heavy tool is quite difficult to hold in their hands. They are difficult to manage. The hand gets tired easily, and therefore require frequent breaks, which reduces performance.
