The importance of choosing the right saw and blade must be your first priority. Otherwise, you can never cut any materials safely. Here are the matters that you must consider while getting a saw and the blade for it.

Confirm the Security Causes First

You can never put yourself or your workmen at risk while doing the cutting work. When the gap between the blade and the saw is anything more than 3mm, it may cause fatal accidents anytime.

That’s why to choose a blade for the saw that is not much smaller or bigger at all. For example, for a 7 ¼ size circular saw, you should never try a blade smaller than a 4 ½ size blade.

Check the Size of the Arbor

No matter how big or small the blade is, the key issue is determined by the arbor of the saw and blade.

When the arbor of the blade matches the saw’s arbor perfectly, they are supposed to work safely and smoothly. So, don’t neglect to ensure that the arbor has no objections.

Teeth Determine Quality of the Work

Whether you will take a blade with more teeth or less, it, in fact, depends on what you want from the machine. In case you are planning to finish the work quickly, a blade with fewer teeth is perfect for you. As the blade can spin quickly, it cuts things within the blink of an eye.

But if you prioritize the finishing and smoothness of the work rather than finishing it early, then the blade with more teeth would help you most. The more teeth the blade has, the more smoothly it can cut the materials.

The number of teeth plays a key role in the quality of the tool and cutting things. So, while getting the blade make sure that you are taking the right one with the correct number of teeth so that you can use it longer with fewer or no stains.

Size of the Teeth Also Matters

As the number of teeth, the gaps between them are also equally important. When the gap is large, the dust and remaining materials get the way to come out at once. So, this time, fewer teeth are better as they offer more gaps between them.

On the other hand, more teeth make the work finished and more accurate. But they don’t allow much space between them.

So, the decision is yours. Do you want the work to be done quickly or accurately?

How Many Teeth Should My Circular Saw Blade Have?

You can find a huge variety in the market in terms of the number of teeth of the circular saw blade. This number starts from 24, which has the highest 120 teeth. Which number you will pick depends on what kind of quality you want from the cutting things, what thickness the material has, etc.

The number of teeth determines how fast or how smoothly the blade will cut the things. For example, the blade with fewer teeth cuts things quickly but roughly. On the other hand, a blade with more teeth cuts slowly but ensures a nice finishing.

  • Safety always must come first. To save yourself from the tiny but speedy and dangerous particles from the metals, take gloves, goggles, and other clothing.
