- How to set up your saw
- Step-by-step instructions for making the cut
By the time you’re finished reading, you’ll be an expert at using a circular saw and you’ll be able to tackle that big pile of lumber with confidence. So, let’s get started!
Circular Saws 101
Before we dive into the specifics of how to cut thick wood, let’s take a quick crash course in circular saws. A circular saw is a handheld power tool that uses a spinning blade to cut through materials like wood, metal, and plastic. It’s a versatile tool that can be used for everything from rough carpentry to finish work, and it’s an essential part of any DIYer’s toolkit.
Types of Circular Saws
There are two main types of circular saws: corded and cordless.
Corded Saws vs. Cordless Saws
Corded saws are powered by an electric motor and require a power outlet to operate. Cordless saws, on the other hand, are powered by batteries and can be used without being tethered to a power source. Both types of saws have their pros and cons, so it’s important to choose the one that’s right for your needs.
Corded saws are more powerful than cordless saws and can handle more demanding projects. They’re also less expensive, which makes them a good choice for budget-minded shoppers.
The downside of corded saws is that they require a power outlet, which can be a problem if you’re working in an area that doesn’t have one nearby. Cordless saws are more expensive than corded saws, but they offer the convenience of being able to work anywhere without being tethered to a power source.
Standard Saw vs. Combination Saw
When it comes to circular saws, there are two main types of blades: standard and combination. Standard blades have a relatively thin kerf (the width of the cut) and a small number of teeth, which makes them ideal for making smooth, precise cuts in wood. Combination blades, on the other hand, have a thicker kerf and more teeth, which makes them better for cutting through tougher materials like metal or concrete.
Right-handed Saw vs. Left-handed Saw
Depending on what you’re cutting and how you’re holding the saw, you may find it easier to use a right-handed saw or a left-handed saw. Right-handed saws are the most common type, and they’re designed to be used with the right hand on the trigger and the left hand on the handle. Left-handed saws are less common, but they can be useful for some applications.
Saw Blades
The blades on a circular saw can be made from different materials, including carbon steel, high-speed steel, and tungsten carbide. The type of blade you need will depend on the material you’re cutting and the application. For example, if you’re cutting metal, you’ll need a different blade than if you’re cutting wood.
No matter what type of saw you’re using, it’s important to choose the right blade for the job. Using the wrong blade can damage your saw and make it difficult to get a clean, precise cut.

How to Use a Circular Saw?
Using a circular saw is relatively simple, but there are a few things you need to know before you get started.
- First, make sure you have the right saw for the job. If you’re working with metal, you’ll need a different saw than if you’re working with wood.
- Second, choose the right blade for the material you’re cutting.
- Third, make sure the saw is properly plugged in or charged.
- And finally, familiarize yourself with the saw’s controls so you can operate it safely and effectively.
Let’s Cut Thick Wood with Circular Saw
Once you’ve got all of that taken care of, you’re ready to start cutting. Here are the basic steps:
1. Place the blade on the material you’re going to cut.
You can do this by aligning the blade with the cut line on the material. When the blade is in place, make sure the teeth are pointing in the direction of the cut.
2. Line up the blade with the cut line.
The blade should be perpendicular to the material you’re cutting. If it’s not, the saw will bind and kick back, which can be dangerous.
3. Apply pressure to the saw handle to engage the blade.
Don’t press too hard—let the blade do the work. Otherwise, you run the risk of overloading the motor and damaging the saw.
4. Slowly guide the saw along the cut line.
Keep the saw steady and let the blade do the work. If you push too hard, the saw will bind and kickback.
5. When you reach the end of the cut, release the pressure on the saw handle and allow the blade to stop spinning.
Never try to stop the blade by grabbing it with your hand. Doing so could result in serious injury.
6. Use a clamp or other tool to support the material you’ve just cut so it doesn’t fall.
If you’re cutting a large piece of material, it’s a good idea to support it with a clamp or another tool so it doesn’t fall and injure you.
7. Repeat steps 1-6 as needed until the job is done.
Now that you know the basics of how to use a circular saw, let’s move on to some specific tips for cutting thick wood.

Tips Cut Thick Wood More Efficiently
Cutting thick wood can be a challenge, but it’s definitely doable with the right saw and blade. Here are a few tips to help you get the job done:
1. Use a corded saw for best results. Cordless saws simply don’t have the power necessary to cut through thick wood quickly and efficiently.
2. Choose a blade with a large number of teeth. The more teeth the blade has, the smoother the cut will be.
3. Use a slow, steady motion when cutting. Trying to rush through the cut will only make it more difficult and can lead to mistakes.
4. Be careful not to overheat the saw blade. If the blade gets too hot, it can damage the wood or even cause the saw to catch fire.
5. Use a support system to keep the wood from falling. A simple clamp will do the trick.
6. Make sure the area you’re working in is well-ventilated. Cutting thick wood produces a lot of dust and debris, so it’s important to have good airflow.
7. Wear safety goggles to protect your eyes from dust and debris.
8. Use ear protection to reduce the noise of the saw.
9. Keep your hands away from the blade at all times.
10. Have someone else nearby in case you need help.
Cutting thick wood with a circular saw can be challenging, but it’s definitely doable with the right tools and techniques.
How to Make a Deep Cut with Circular Saw?
Deep cuts are usually necessary when you need to cut through thick materials like lumber or plywood. The following tips will help you make deep cuts safely and efficiently:
1. Use a sharp saw blade. A dull saw blade will cause the saw to bind and kick back.
2. Set the depth of the cut. Make sure the depth of cut is not more than 1/4 of the blade’s diameter.
3. Use a guide. A guide will help you make straight cuts.
4. Use clamps. Clamp the material to the table to prevent it from moving.
5. Use both hands. Keep a firm grip on the saw with both hands.
6. Be careful of kickback. If the saw binds, it can kick back and cause serious injury.
Can a 6.5-inch Circular Saw Cut 2×4?
Yes, a 6.5-inch circular saw can cut through a 2×4. However, it will be more difficult than if you were using a larger saw. The reason is that the 6.5-inch saw has a smaller blade, so it will spin more slowly and create more friction when cutting. This can cause the wood to burn or the blade to overheat.
If you must use a 6.5-inch circular saw to cut through a 2×4, here are some tips:
- Use a sharp blade- A dull blade will cause the saw to work harder and can lead to burning or overheating.
- Make sure the wood is firmly secured– If the wood is not securely clamped down, it can move while you are cutting and cause the saw to bind.
- Cut slowly and apply steady pressure– Cutting too quickly can cause the saw to bind or overheat. Apply steady pressure to the saw as you cut slowly through the wood.
How Thick of Wood Can a 5 1 2 Circular Saw Cut?
Most 5 1/2-inch circular saws can cut through wood that is up to 2 inches thick. If you need to cut thicker wood, you may need to use a different type of saw. Some 5 1/2-inch circular saws can cut through 6 inches of wood, while others may only be able to handle 4 or 5 inches. It’s best to consult your saw’s manual to be sure.
The Bottom Line
Cutting thick wood with a circular saw can be challenging, but it’s definitely doable with the right tools and techniques. Be sure to use a sharp blade, set the depth of cut properly, use a guide, and clamp the material down before you begin cutting. And always exercise caution when using any type of saw.
