A circular saw is a power tool that may come with a cord, or it may be cordless, and using a circular saw means attention to safety must be paid. Discover the importance of noting that a circular saw will cut thicker than a drawn line with help from an independent contractor and carpenter in this free video on power tools.
I'm Jeremiah Fox. I'm a carpenter and handyman out here in New York City. How to use a circular saw? Now, a circular saw is a power tool and so, when we're working with power tools we want to always make sure we're safe. So, the most important part of safety is always your eyes, so you have your safety glasses. And then, circular saws make a lot of noise, as most power tools do, so you want to have ear protection with either foam inserts or earmuff-type devices. If you feel the need and the stuff you're cutting, you can also have a dust mask to cover your mouth. For this project, we're not going to need that. There's two main styles of circular saws these days, there's the traditional corded model and then there's the new cordless that works with all your screw guns and other packages. They're essentially the same, ones just powered from your wall, one's powered from a battery. So to use a circular saw, you take the piece of wood that you're going to cut, get your tape measurer out, we're going to cut this board at a foot, make two marks, take a straight edge or a square, then you have your line. So, it's important when you're cutting a piece of wood to know which side of the line you want to take out because your saw is wider than your pencil line is. So, if you want to keep the full foot, you'd want to cut on this side of the line and then, if you want to take that foot away or you're saving the rest of it, you want to cut on this side of the line. As a rough guide, you can also use this notch here that even has a little marker here so you know where your blade's going to go. So then, making sure that your safety gear's in place, pull the saw back so that the blade's not touching the wood, take the safety off, pull the trigger and then begin the cut. And now you have a nice new piece of wood, cut to dimensions, with your circular saw.
