What I don’t Like

1. Battery not included: This saw does not come with a battery, so you’ll need to purchase one separately.
2. Blade not included: The DeWalt DC390B doesn’t include a blade, which means you’ll have to buy one separately.
3. No dust port: There is no dust port on this saw, so you will need to use an external vacuum cleaner or dust collection system for clean up.
4. No laser guide: Unlike some other circular saws, the DeWalt DC390B does not feature a laser guide, which can be helpful for making straight and accurate cuts.
5. Inadequate depth adjustment: This saw has limited depth adjustment capabilities, which can make it difficult to adjust the depth of the cut without having to repeatedly measure it out each time.

How to Cut a Perfect Circle with the DEWALT DC390B 18-Volt Cordless Circular Saw

Cutting a perfect circle can be tricky, but with the right tools and techniques it’s easily achievable. The DEWALT DC390B 18-Volt Cordless Circular Saw is an ideal tool for making precise cuts over a wide range of materials. Let’s look at how you can use this saw to cut a near-perfect circle.

First, make sure you have all your materials ready: the DC390B, a straight edge, and a sharp blade, preferably one designed specifically for cutting circles. You will also need safety glasses, hearing protection and gloves.

Next, use the straight edge to draw a line around the circumference of your circle. Make sure that your line is as straight as possible; if necessary, use a ruler or other straightedge to double check. Now clamp the material in place so that it won’t move when you start cutting.

Once your material is clamped down, set up your saw according to its instructions. Make sure that your blade is securely attached and that it is at least 1/8 inch wider than the line you drew earlier. Then adjust your saw to the appropriate angle for making a clean cut along the line.

Now it’s time to start cutting! Hold the DC390B firmly in both hands and position it on top of your material at the starting point of your line. Start slowly and steadily guide it along the path of your drawn line until you reach the end point. Take care not to move too quickly or put too much pressure on the blade – this could cause it to break or become damaged.

Finally, inspect your work – if there are any jagged edges or imperfections, sand them down before finishing up with some varnish or paint. And there you have it – perfect circles every time using the DEWALT DC390B 18-Volt Cordless Circular Saw.
