What is a Circular Saw?
It’s a power-saw with a disc shaped toothed blade that cuts through wood pieces and other material when the blade rotates spontaneously. Apart from regular wood stocks, you can cut plastic, masonry, metals, and some other materials using circular saw. Different materials require different types of blade for cutting effectiveness and efficiency. A circular saw can get you rip-cuts, crosscuts, bevel cuts, and combination of all of them.
Depending on the type, circular saws can be hand-held or fixed to some machines. Although most saws are powered by electricity, some models are gasoline and hydraulic powered. An electrically powered circular saw will be more than enough for professional and DIY uses.
You have the option to go for either a corded or a cordless battery powered circular saw. Cordless ones provide relatively more power than the battery powered ones.
