Setting Up And Adjusting A Circular Saw

Hand-held circular saws were invented about 100 years ago and since then, constantly improving, hold the title of one of the most popular and useful tools. However, certain alternatives for cutting various materials already exist. Therefore, it is worthwhile to figure out what kind of unit it is and how to operate it correctly.

Advantages and disadvantages

A circular or circular hand saw is not the only way to cut various sheet materials, however, it is considered one of the best solutions when competing with jigsaws and even more so with classic hand saws driven by manual force.

This in itself indicates certain advantages of its use, however, let’s take a closer look at why such a tool is better than alternative options.

  • The tool is powered by an electric motor, it is relatively little dependent on manual power, which is needed only for holding. Thanks to this, productivity improves, and the operator gets tired much less.
  • Unlike most other saws, the cutting part of the circular saw is made in the form of a disk, sharp throughout the circle. Thanks to this, the unit has no return movement. absolutely all efforts are spent on useful work.
  • Being originally developed specifically for cutting wood, today a circular saw can be created for other materials. Although their list is not unlimited, there are still options for tiles and some soft types of metal.
  • A hand saw can be equipped with a battery and work from it, which greatly expands the scope of potential use. Cordless models can go without a power outlet for several hours, therefore they can be used in any working conditions, be it construction without utilities or the roof of the building.
  • Compared to the same jigsaw, a circular saw is characterized by significantly increased productivity. over the same period of time, it is able to cut much more lumber.
  • Unlike a chain saw, a circular saw is good in that it allows you to make the cut even, rather than tearing it, which is why it is better for cutting decorative materials.
  • Most hand saws offer built-in safety measures that are definitely not the case with classic hand-driven saws. over, the presence of special nozzles allows even a vacuum cleaner to be connected to many models, which ensures cleanliness in the workshop and safety for the operator’s health.

Of course, with all its positive qualities, the circular saw is still not alternative. that means, at least in some situations, it cannot show itself perfectly. Perhaps in your conditions nothing else is required, but you should know about this and possible pitfalls in advance, therefore, we will separately consider the possible disadvantages.

  • The operation of the device is impossible without electricity, which means that you either have to be near the outlet if the device is plugged in, or remember to charge it on time if it is battery. At the same time, some batteries require certain specific requirements. for example, popular lithium-ion batteries tend to discharge much faster at sub-zero temperatures.
  • The circular saw is absolutely not intended for a figured cut, the cut will always be strictly direct and in any conditions, except with slight deviations. There is no way to perform curly cutting using such an aggregate. in this it can only be replaced with a jigsaw.
  • Battery models are good for their mobility, but increasing their functionality, performance or autonomy will certainly lead to an increase in the weight of the unit. Because of this, a really powerful tool on batteries simply does not exist, and the thickness of the cut of the same wood in such a device is usually limited to 7-8 centimeters.
  • A circular saw is not so expensive, but still significantly more than a classical one. In practice, this means that if there is doubt about the regularity of using the tool, its purchase may not be practical.

Application area

Providing an even, and most importantly, fast longitudinal cutting of the board, a hand-held circular saw is usually considered a professional tool that most often finds application on a sawmill. where lumber is produced on an industrial scale. In such conditions, large stationary units are mainly used, but in small enterprises the use of battery options is also possible. Accordingly, other enterprises engaged in cutting other materials available for cutting, the same light alloys, may be potential users of such an aggregate.

Even more intensively battery models are used by repair masters, who are forced to regularly carry out cutting of building materials on the road, in the most unpredictable conditions. Such professionals value the tool very highly, because with its light weight it allows you to easily and quickly equip a kind of exit workshop.

The ability to change the disk and its rotation speed depending on current needs allows you to work with different materials, and an electric drive helps to significantly speed up the sawing process.

For the home, such tools are still relatively rarely used, and meaning in their purchase is only if you have your own personal plot and a certain tendency to carpentry. Living in a city apartment and not having its own workshop, it is possible to use such a device unless for the same repair needs that were described in the paragraph above, however, in the conditions of a summer residence, the possibilities of application are expanding. So, with the help of a battery device, you can even trim small branches, and then cut them to use as fuel. In combination with other types of saws, circular saws can also be used for cutting felled trees.


Understanding the main technical characteristics and their adequate assessment is the main key to the correct choice of model. To better navigate in the variety of model series, we consider the main features of the units. Perhaps the main characteristic is engine power, it depends on how much a large drive such a unit can rotate at a decent speed, and the maximum allowable cut depth depends on the diameter of the drive. In the tools of the initial level, the power is very modest. not higher than 1.2 kW, therefore such a tool is not enough, however, and the productivity will be low: the circle with a diameter of 13-16 cm saws no deeper than 4.5 cm.

Saws of the middle class have a power in the range of 1.2-1.8 kW, thanks to the disks up to 20 cm in diameter, it is possible to cut to a depth of 6 cm, such units are already stationary, and are used for country needs and field repair work. Equipment more powerful than 2 kW is already considered professional, it allows cutting up to 100 mm. Such saws are almost always network and stationary, since it is difficult and dangerous to keep them in the process of working on weight, so this is usually an integral attribute of a sawmill.
