5 Easy Steps to Cut Thick Wood with a Circular Saw


Power tools, including woodcutting circular saws, have been among the most imported products in the United States, having an import value of about 4.52 billion last year. This shows the importance of these tools and their need in the upcoming days for multiple purposes in the house and outdoors. 

When it comes to woodworking, a circular saw is preferred by DIYers and carpenters because of its wide range of features. Unlike a table saw, it can easily be transported across multiple places because of its lightweight.  Also, its sharp blades with high-grade steel and smooth base offers accurate cuts, which makes the beginner a pro.

That’s why a circular saw is the first choice for cutting either steel, masonry, ceramic tile, or thick wood. Cutting thick wood might be a problem even for an experienced woodworker. In this case, a circular saw makes the cutting safe, easy, and accurate. Let’s find out how a circular saw does the job and makes cutting a thick wood easy.

How to Cut Thick Wood with a Circular Saw?

It might not be easy to cut thicker wood than with a circular saw blade, even when you’re an expert. This requires skills to get yourself protected, the best circular saw for accurate cutting, and a working technique to cut the thick wood right.

We made it easy for you by coming up with the five easiest steps, helpful for beginners and experts to cut thick wood. Make sure you go through the steps one by one, or you may ruin the entire process.

Step #1: Measure The Wood Thickness and Adjust Saw

Start with measuring the wood thickness and saw size. Make sure the thickness doesn’t exceed double the size of the saw. Otherwise, it can be challenging to safely cut the wood. If the wood thickness is less than double the saw size, you’re good to go. In other cases, use the blade with increased exposed saw size.

Step #2: Get the Wood into a Perfect Position

Place the wood at the end of the stand for accurate and precise cutting. Also, it avoids injuries and keeps you protected while going through a risky cutting process when the saw blade is exposed and causes damage. In addition, make sure to place the wood on a stand where you can have a good grip for comfortable cutting.

Step #3: Mark the Cutting Area with Pencil

Now grab the marking tools, including a pencil, scale, and measuring tape. Using a led pencil, mark the exact spot from where you want to cut the wood. Also, make sure to mark the entire wood from all sides as it will give you precise cutting from every side. Marking will help you make precise and accurate cutting that’ll also avoid wasting wood due to wrong cutting.

Step #4: Adjust the Circular Saw Blades

Since you’ve already measured the wood thickness and marked it as well, it’s important to adjust the circular saw blade accordingly. You can’t just cut using a blade of any size because it won’t offer perfect cutting. Know about your saw first and adjust the setting feature as per the wood thickness.

Step #5: Start Cutting

Before you start cutting, make sure you’re in a comfortable position, the stand is stable, and your hands are not sweaty. Once your ready, make the cut. Keep your hands still for accurate results. If you’re new, practice on wasted wood so you do not ruin the new one.

Bonus Tips

Now you know how to cut thick wood with a circular saw, let us give you some bonus tips that can make your cutting experience safe and accurate.

Tip #1: Wear Safety Gear While Cutting Wood

If precise cutting comes with a cost to your health, it’s not worth doing. So, to avoid such a risky situation, we recommended using safety gear while cutting wood. For example, cutting wood causes a lot of dust and splinters that cause severe health issues. The dust, when inhaled, causes heart and lung disorders and, when not inhaled, causes eye problems.

So, wear a mask and glasses to prevent the dust from entering into your eyes and being inhaled. Also, wear safety gloves that keep your hand steady for accurate cutting and protect against serious injuries. You can wear earbuds to protect your ears against noise produced by a circular saw.

Tip #2: Store the Saw in a Safe Position

When you’re done with the cutting process, store the saw in a safe position. As the saw requires maintenance for prolonged life, it’s important to keep it in a safe place. Additionally, keep the saw unplugged and away from your kids to avoid injuries. Cleaning the saw helps it last longer to make the purchase budget-friendly, so swipe the blade and run oil through the saw for smooth working.
