            How To Choose The Best 12-Inch Sliding Compound Miter Saw?

            Power Options

            Most corded miter saw motors have 10Amp, 12Amp, or 15Amp motors.

            While more amps mean more power, you can handle most jobs with a 10Amp motor. On the other hand, a higher-power motor allows for cutting larger boards and they don’t heat up quickly if used constantly.

            Cordless miter saws usually come with a 20V battery and can handle 150-275 cuts on average with one charge.

            Blade

            When talking about the blade, we mean the blade size. As a rule of thumb, a larger blade will make larger cuts. Typically, you can choose either 10 inches or 12 inches in size, but you can also find small blades of only 4 inches in size.

            In addition, you need to think about the tooth count.

            Larger blades tend to have more teeth and smaller ones will have fewer teeth, and with the same blade size, the more teeth the smoother the cuts.

            However, if you cut thick material, you should get fewer teeth.

            Cutting Ability

            The cutting ability is very important as the accuracy of the cuts and the cutting angles.

            • Bevel: it allows the saw to tilt and rotate the base, which helps you change the cutting angle. You should examine the bevel when browsing miter saw models.
            • Reliable lock: a reliable lock maintains the lock position so that the saw won’t move out of place when you’re cutting. This will make sure the cut is accurate and ensure safety for you.
            • Positive stops or predetermined positions: these factors are set to the most common cutting angles. This way, you can alter your cut for the specific angles. Some saws even have switches that let you change cuts quickly with just one touch.

            Safety Features

            There’s no denying that saws pose certain dangers to the user, which is why you must look for safety features.

            • Saw guard: the name suggests what it does, helping you avoid accidents.
            • Saw stand: it provides better cuts and a stable base as you cut.
            • Electric brakes: they quickly halt the blade when you need to.

            It’s worth an investment if you use it for the right purpose, which is cutting bevels and miters into wide boards.

            Do I really need a dual bevel miter saw?

            You will need it if you want to make your work easier, quicker, and more professional. If you are a regular user and don’t do projects very often, you may not really need it.

            How big of a board will a 12-inch miter saw cut?

            A 12-inch miter saw can cut a 2x8 board at 90 degrees.

            Should I get a 10- or 12-inch miter saw?

            The answer to this question depends on your own needs and preference. A 10-inch saw spins faster while a 12-inch saw spins more slowly. A 12-inch saw has more cutting power and cutting capacity, but a 10-inch saw offers smoother and faster cuts. On the other hand, a 10-inch saw costs less.

            Will a 12 sliding miter saw cut a 6x6?

            According to many users, a 12-inch sliding miter saw won’t cut through a 6x6 board.
