Circular or circular saw is designed to work with wood and other materials. With the help of a disc mounted on the case with cutters, sawing is performed at high speeds. There are various types of circular saws, which also include angle saws.
A circular saw allows you to make a neat, even cut of wood or large plywood sheets. This is especially convenient when it is not possible to use sawing special tables.
There are two types of circular portable saws: left-handed and right-handed, which can be connected to the mains or run on battery power. When choosing circulars, it is necessary to pay attention to the following points.
An important factor is the weight that a hand-held circular saw has. The mass of various models can vary from three to six kilograms. Wireless devices add extra weight to the battery. Therefore, when buying a tool, you should hold the saw in your hands for a while to feel its weight. For simple homework, a 15-amp wire model will be enough, the cost of which can be below $ 100.
When choosing a tool, you need to consider the size of the blade, on which the depth of immersion in the tree depends. The larger the circular saw has the size of the blade, the deeper the cut can be done. Small-blade devices are easier to maneuver, however, in any case, the size of the material to be sawed must be taken into account.
Many models have a feature that allows you to change the angle of the blade to cut at different angles. For a more accurate performance of the work, a circular saw with a goniometer will be required, on which every degree will be marked.
An important role in choosing a tool is played by the position of the motor. For saws with a chain drive, the engine is placed on the same level with the blade, and for tape motors the motor is located away from the blade. The chain driven device is more powerful and can cut bulk wood, stones and even concrete. The disadvantage of this type is the high cost and heavy weight. If the plans do not include work with metal and other similar materials, then a conventional circular saw is completely suitable.
When making a purchase, you need to look for additional features. These include dust collector, laser pointer, emergency lock. You need to compare several models, hold them in your hands, check the switch, look at the maneuverability of the tool, try to adjust the blade.
Right-handed saws are considered more camphor in work, they easily glide along the working surface and do not have a large weight.
A circular saw, a stationary hacksaw use a blade. For circulars, these components differ in the material from which they are made and in diameter. It is best to use a set of different blades.
Working with a circular saw is dangerous. Therefore, you must follow the safety rules and take measures to protect the eyes.
