Circular Saw Blade Size

To find out how to measure a circular saw blade size, first, you must learn about the diameter of the blade along with the tooth and the gullet. When you replace it with a new one, each of these is necessary.

The Diameter of the Blade

If you are a user of a circular saw, you already know about the blade size of the circular saw. However, if you are new, we will discuss it in short. First, you must learn that the difference between the circular blades is measured by diameter.

There are some common blade sizes that most of these saw owners use. The 7 and ¼ inches blade is a blade that you will find in most DIYers’ boxes. This blade is the perfect one if you want to cut materials that are three inches or close. You can cut wood of three inches or close with such blade diameter.

Along with this, you can cut other materials apart from wood with this woodworking circular saw’s blade diameter. However, the next common blade size for this saw is 6½ inches. This one is designed for lighter cutting work. And then, there is another one that is most used by the users which are 8 ½ inches.

If you plan to go for heavy-duty work or to cut thicker materials than the three inches, you can use this one! However, at times, you might require cutting materials there are way thinner than the ones we have mentioned. In that case, the best circular saw blade is 4 ½ inches. If you are a DIY-lover and you deal with cutting paneling and such thin wood or other materials, you can settle for this one. Some people often try to cut dimension lumber with the 4 ½ inches diameter blade and this works for it!

Method 1

In this way, you have to open the guard of your circular saw at first. Open it and hold that with one of your hand. Now, take a measuring tape and start measuring from the edge of one tooth of your blade. And take your measuring tape to the edge of the table. If you are not sure, you can go for another tooth and measure it.

Method 2

Here, you have to set up the straight edge just the way you plan for cutting any wood piece. Make sure you clamp it properly. Get your circular saw and certify that the blade is added. Now, all you need to do is a quick cut.

After doing the quick cut, you have to take the tape measure and measure the distance between the cut and the clamped piece. And yes, this will be the exact measurement of the blade in inches!

The Number of Teeth

As we all know, the more teeth on your saw, the smoother and finer cut you will get. However, when you plan to get a circular saw blade, you have to work on the number of teeth too. In short, we will explain this to you.

The tooth counts of the circular saw have a variety. From 14 teeth to 120 teeth, you will get circular saw blades of all sides. If you want the perfect blade, you must ensure that the number of teeth is correct. Let us learn the details:

14-Tooth Blades: Demo Blade

The circular saw blade size that has 14 teeth is the right deal to go if you want a rougher cut. However, the best part is these saw blades can cut the material faster than the others. Also, these are perfect for thicker materials. Count the blade and you will know which one is right for you. And never settle for this blade if you want to cut thinner materials.

24-Tooth Blades: Framing Blades

If you count and see that your circular saw blade has 34 blades, this is the standard framing blade. These saws are usually 71.4 inches. For clean rip cuts, these are just the ideal ones. However, it will result in rougher crosscuts. For the framing work with the 2x stock, such blades are the best deal.

40-Tooth Blades: Sheet Blades

These are specially designed for sheet materials and users use these for plywood. If you are working with thin veneers, the sheet blades are the right ones. However, if you plan to cut MDF, we recommend you go for 90-tooth to 120-tooth blades.

80-Tooth Blades: Miter Saw Blades

When there is a lot of work and you need a blade that can go smooth, this miter saw blade for your circular saw can be incredible. If you want to install the crown molding, you will surely need something that can cut clean. Crosscutting in an angle or cutting miters will require you an 80-tooth blade. The higher the tooth, the better cut across the grain! Go for more teeth if you need more perfect.

The Gullet

There are teeth placed on the circular saw and the distance between a tooth to another tooth is called the gullet. Yes, sometimes, the larger blades and the smaller blades have the same gullet! The size of the gullet is as important as the depth of the gullet. Measure it with your measuring from one tooth to another. Also, check out how deep the valley is with the measurement tape.
