11 Steps on How to Cut Thick Wood With Circular Saw

You must follow specific steps to cut thick wood with a circular saw. Given below are those steps:

Step 1: Get the Right Circular Saw

The first step is ensuring you have the right tool for the job. You’ll need a circular saw to handle cutting through the thick wood. This is important because you don’t want to damage your saw or injure yourself. Most recommend getting a circular saw with at least a 7-1/4 inch blade.

Step 2: Choose the Right Blade

Now that you have the right circular saw, you must choose the right blade. The blade you use will be determined by the thickness of the wood you’re cutting. So, for example, if you’re cutting thick hardwoods, you’ll need a different blade than just cutting through softwoods.

Choose the Right Blade

Step 3: Set Up Your Work Area

Before you start cutting, you need to set up your work area. This means making sure you have a flat, level surface to work on. You also want to ensure that there’s nothing in the way of your saw blade. Otherwise, you may end up damaging your saw or injuring yourself.

Step 4: Mark Your Cut

Once you have your work area set up, it’s time to mark your cut. This is important because it will help you stay on track while cutting. Use a pencil or marker to draw a line where you want to make your cut. Also, ensure that the line is straight.

Step 5: Start the Saw

Now it’s time to start cutting. First, place the blade of your saw on the line you marked in Step 4. Then, hold the saw with both hands and form the blade; slowly lower it into the wood once the blade is spinning. After that, you can start moving the saw forward. Don’t ever force the saw; let it do the work.

Step 6: Cut Slowly and Steadily

As you’re cutting, make sure to go slowly and steadily. You may damage the blade or make a mistake if you go too fast. It’s also important to keep the saw level as you’re cutting. This will ensure that you make a clean, straight cut. Again, you can take help from a guide if needed.

Step 7: Finish the Cut

Once you’ve reached the end of your cut, it’s time to finish it. To do this, slowly raise the blade out of the wood. Then, turn off the saw and set it down. Take every bit of pressure off the blade before you move it. Otherwise, you may damage the blade.

Step 8: Check Your Cut

Now it’s time to check your cut. First, make sure that it’s straight and level. If it’s not, you can use a saw to make adjustments. Remember to go slowly and be very careful not to damage the wood. You can try different techniques until you’re happy with your cut.

Remember to go slowly and be very careful not to damage the wood. Don’t forget to check your saw’s blade to ensure it’s still in good condition.

Important Tips You Need to Know to Avoid Common Mistakes 

Strictly follow these tips while cutting the thick wood with a circular saw and ensure the safety of yourself and others.

  1. Always use a sharp saw blade. A dull saw blade will not only make it harder to cut through the wood, but it can also cause the wood to splinter or crack.
  2. Make sure the saw is secured correctly before beginning to cut. You last want the saw to slip and cause an injury.
  3. Use a push stick or other device to help keep your fingers away from the blade while cutting.
  4. Apply even pressure as you’re cutting through the wood. If you apply too much pressure, the saw may bind up; too little pressure and the cut will be uneven.
  5. Follow the manufacturer’s recommendations for the maximum depth of cut for your particular saw.
  6. Use a slower speed when cutting thicker pieces of wood. This will help to prevent the blade from overheating and becoming damaged.
  7. If the wood is particularly thick or hard, you may need to make several passes with the saw to complete the cut.
  8. Always wear proper safety gear when using a circular saw, including eye protection.
  9. Use a clamp to secure the piece of wood you’re cutting if possible. This will help to prevent kickbacks and other accidents.
  10. Be sure to clean out the saw blade after each use to prevent the buildup of sawdust and other debris.
  11. Inspect the saw blade regularly for damage and replace it if necessary.

How Thick Can You Cut With Circular Saw?

The answer to this question depends on the type of circular saw you have. Some can only handle cutting thinner material, while others are built for thicker wood.

If you’re trying to cut a very thick piece of wood, it’s best to use a heavy-duty circular saw. These saws can handle thicker material and make the cut more smooth.

Heavy-duty Circular Saw

When cutting thick wood, it’s important to use the right blade. A thicker blade will be able to handle the material better and will make a cleaner cut. Read the manufacturer’s instructions on what type of blade to use for your particular saw.

It’s also a good idea to make multiple passes with the saw instead of trying to cut through the entire thickness at once. This will help prevent the blade from getting bogged down and make the overall cut more accurate.

With a bit of practice, you’ll be able to cut thick wood quickly and easily with your circular saw. Just be sure to use the right blade and take your time to get a clean, precise cut.


To cut a piece of wood that is thicker than the saw blade, you will need to do two things: make relief cuts and use a guide. Make sure you are comfortable with all the safety features before attempting to cut wood. If you have any questions, consult a professional before proceeding. You can cut through even the thickest pieces of wood with practice and caution like a pro!
