A circular saw is the handiest and most versatile saw you can own. Whilst it may not have the precision of a table saw, the circular saw is much easier to transport and use on the go. Circular saws are excellent for DIY jobs and for commercial use. The circular saw can be used for cutting large pieces of wood, plastic, metal, concrete or most any other material such as tile or brick. It can make straight cuts and curvilinear cuts.
When choosing a circular saw, you need to consider the purposes of its usage so you can choose the right power level and the correct accessories for the job. You will also need to think about what type of braking systems works best for you and how often you will use the saw. There is no point in paying for the most expensive commercial use circular saw when you will rarely use it and mainly only use it for small, here and there jobs.
