You want to buy a circular saw for your woodworking shop, but you are overwhelmed by the multitude of models available on the market. This article presents the essential points to evaluate in order to make the best choice.
Your needs
To choose the right model of circular saw, you must first define your needs. Indeed, like the Makita DHS680Z circular saw, most models of circular saws are designed for specific needs. For example, for large and regular jobs, prefer a corded model. On the other hand, for occasional wood cutting, opt for a battery-powered circular saw. Furthermore, to be well-equipped, you can acquire one model from each category of circular saw.

The cutting efficiency of the device
A good circular saw must have adequate cutting efficiency. This parameter is assessed by considering the power of the machine. Indeed, the higher the power of a circular saw, the more effective it is on large pieces of wood. However, this is not sufficient to make a decision. The efficiency of a circular saw also depends on its no-load speed. This indicates the number of revolutions made by the blade per minute when it runs at full power and solely under the influence of air. A minimum of 4500 revolutions per minute is required to achieve quality cuts.
The diameter of the blade

The blade diameter of the circular saw model you choose must correspond to your cutting needs. This selection criterion is closely related to the cutting depth of the circular saw and, by extension, to its efficiency. With a circular saw whose blade diameter ranges between 160 and 170 mm, cuts of approximately 55 mm depth can be achieved. By choosing a model with a blade diameter of 185 mm or 190 mm, the depth is respectively 60 mm or 65 mm. Finally, if you want a depth of up to 85 mm, a blade with a diameter of 230 mm is required.
The number of teeth on the blade
A radial saw with a blade that has a high number of teeth has the advantage of being precise. Therefore, it is important to check the number of teeth on the blade of the circular saw you are interested in before purchasing it. Generally, circular saws have a minimum of 12 teeth and a maximum of 48. However, you can start with a model with fewer teeth, considering changing the disc later.
The ergonomics of the device
The circular saw should have good ergonomics to be easy to handle. Check if the controls of the machine you want to buy are easy to manipulate. In addition, ensure the presence of a cutting guide that allows for better cutting precision. However, this equipment may be optional.
The circular saw is a cutting device that allows for a wide range of cuts without much effort. To choose the model you need, consider all of these criteria.
