According to experts, circular saws are the best tools for implementation of cross or longitudinal cutting of different materials. But when choosing such saw it is necessary to be guided by certain criteria.
Professional and household circular saws
Circular saws allow to carry out cut with the maximum accuracy of corner and smooth edge. But during the work with some materials guides can be required. By the way only professional tools are completed with the directing tires. There are models in which guides are integrated into design of saws.
Circular saws for professionals are equipped with the powerful engine allowing disk to rotate with teeths with high speed. Important characteristic of such saws it is considered to be depth has spent on drink. Depending on it saws are divided into small, average, big and professional.
For household application it is recommended to choose small and medium circular saws with the maximum depth has spent on drink up to 55 mm. In the production purposes it is necessary to use only big saws. Their depth has spent on drink can reach 70 mm. Besides, big saws allow to saw through both thin, and thick material. At the enterprises of the woodworking industry, professional saws with depth are usually applied has spent on drink up to 140 mm.
What to pay attention when choosing circular saw to?
Circular saws of the average and small size are very much appreciated because of the portability. They are preferred to be used on remote objects. And big saws are stationary. These large-size and powerful units are simply irreplaceable in the course of construction of buildings. Depending on features of future application all saws can be subdivided into four categories. These are saws for end-grain cutting of wood, for ripping cut of wood, for cutting of non-ferrous metals and also for cutting of the laminated chipboard. When choosing circular saw it is necessary to consider that not all models perform immersion function. For example, if the ripping cut has to be done from the middle of board, not to do without such function. Saws with function of immersion differ in the increased performance and maneuverability. Convenience of capture of the front handle are also important criterion when choosing circular saw. Controllability degree the tool depends on it. The spherical handle which allows to record saw in any necessary situation will become preferable option. Upon purchase of saw the tool cost is considered important criterion. Usually the price raises if the circular saw allows to regulate speed or to include the mode of expeditious cooling. Before acquisition of the tool it is necessary to decide on necessary additional functions not to overpay for unnecessary "frills".
