    When choosing a circular saw, you have different options such as corded and cordless, and they are rated based on the type of blade they accept. Here we have a 5.5-inch, a 6.5-inch, and a 7.25-inch saw. There are different blades designed to cut different types of material, such as metals, woods, and plastics. In general, the more teeth-per-inch, or TPI, the finer the finish.

    I’m going to be using a 7.25-inch circular saw, and before we get started we always want to make sure we’re disconnected from a power source.

    To adjust for the thickness of your blade, you want to unlock this lever to release the shoe and set it to the depth of the material that you will be cutting. Once it is set, secure it back in place. And you can check yourself by opening up the guard, setting your piece of material against the shoe, and making sure no more than three teeth are showing.

    To create angled cuts with a circular saw, you can bevel the shoe and set it to your desired angle.

    If you need to change the blade, you’ll want to find the tool to remove the screw. A lot of times, it comes on board. Make sure that when you are loosening, you hold onto that spindle lock. If not, the blade will continue to spin with you.

    Once it is loose, you want to make sure that you don’t lose any of the components, because you’re going to need those to put the blade back on.

    To get to the blade, move your guard and safely take out the blade. To install your blade, you’re going to want to hold that guard up, make sure the arbor matches the blade you’re using, and set all the components back where they were. Put the guard back, press the spindle lock, and tighten secure.

    And now we’re ready to make a cut. To set up our work surface, make sure the heavier portion of the saw is above the supported surface. Set your piece in place and clamp it down. Hold the shoe of the saw flat against your surface and align it with the line. Always make sure your blade is in full motion and away from the material before starting your cut. Keep the cord away, and make sure it never crosses your workspace.

    Thanks for watching!
