First of all, it is necessary to Ascertain that circular saw is Appropriate for a particular job, as by the design of this tool you will find:

• Stationary – really a machine, which can be a saw mounted onto a frame. Requires free space in the workshop, and occasionally a separate room. Designed such a circular saw to get permanent processing of timber moyakovka.ru, and in massive volumes.
• Table – the prior version in miniature, installed on another workbench or desk, can also be employed for sawing a large volume of timber, as an example, during the building of the tub.
• Manual – a portable tool, created for processing workpieces in different planes. Here is the most common sort of circular saw, however the least powerful of the described. After functioning, it requires periodic break, and is utilized for sawing small amounts of substance.

Hand-held tool is much more flexible than static variants. It costs considerably cheaper, but under certain conditions can cope with the same tasks, though with less efficiency. When picking it, you ought to be guided by the standards below.

Power

According to the type of power supply, circular electrical saws are divided into 2 classes:

• Networked – that they operate out of a domestic electric network of 220 V. If we discuss professional machines, then they require a lineup of 380 V. The drawback of the connection option – the requirement to have an electricity grid in the area of work, in addition to some inconvenience of operation due to the cable.
• Cordless – operate in stand alone mode, additionally require the presence of a socket, but to control the battery, therefore their radius of performance isn’t constrained by anything. Depending on battery capability, they could work on a single charge not more than 50 minutes.

The second choice is reasonable to purchase only if for some reason it is impossible to use the mains found. Form of work

Standard circular saws are designed for sawing wooden workpieces at different angles, but there are also special versions of this tool:

Submersible saws – come in stationary and handheld versions. Their difference is in the fact that the saw blade in the initial place is within the workpiece, able to seep into its own centre. This enables you to start cutting not with the border of this substance, cut through holes.

Metal round saws are powerful models which are equipped with stronger or abrasive discs. Capable of cutting sheet metal, pipes, profiles. Some of them manage wood equally well.

The width of the disk directly is dependent on the ability of this saw’s electrical motor. The more powerful the instrument, the larger the disk it is in a position to rotate, the more secure the rotation frequency of the latter, the longer the duration of constant operation, the less probable the wedge. In addition, powerful saws permit you to process thicker material, but in addition they are heavier. Thus, by way of instance, versions at two kW on average weigh 7 kg, whereas 1.2 kW – approximately 4 kg.

According to the energy saws could be divided as follows:

The larger the width of the disk, the more powerful the electrical motor needs to function, the thicker the workpieces the saw will use. Seating diameter is another parameter that decides if a specific disk will fit the selected saw.

At higher speeds, less torque is necessary for sawing, which means dense substance is simpler to take care of. Keep in mind that with higher RPM the warmth of this substance in the area of touch with the saw increases, exactly the same plastic or laminate needs less RPM. Ideally, it is much better to select a saw with adjustable rate.
