However, variables are there as the way of using the circular saw, frequency of using the saw, and the original blade quality, and many more are behind the query of how long a circular saw blade lasts. It means it all depends on your project.

In this article, I have discussed the time-frame of replacing a circular saw and how to change a circular saw blade. Let’s roll together to learn more.

When to Change a Circular Saw Blade?

If you are not facing any problem during a cutting performance, then probably your circular saw blade is still sharp and durable enough. But when the below red flags are showing, note that it is time to change your circular saw blade.

  • Uneven cutting
  • Extreme burning
  • Force push-through
  • Fragmenting and binding

All the above signs are an indication of a faulty circular saw blade. If your circular saw starts showing these problems, then it is high time to look at the blade of your circular saw intently. Then decide whether you will clean or replace the circular saw blade.

5 Simple Steps on How to Change a Circular Saw Blade

Consider the following steps as the safest way to change a circular saw blade. Don’t do anything that is not described below to avoid any risk.

Step – 1:

Do you own a corded or cordless circular saw?

If it is a corded one, unplug the circular saw first. If it is a cordless circular saw, remove the battery from it. This will keep you risk-free from any unwanted firing up of the blade during the time of replacing the blade.

Step – 2:

Choose a secured surface where you need to place the circular saw. Also, the blade guard needs to be removed. It will let the blade be exposed. Check whether your circular saw has an arbor lock or not. If yes, don’t delay to engage it.

The arbor is a type of shaft where the blade is placed on. And if you lock it, the blade will be in its place steadily, and unlocking will release the blade. And if there is no arbor lock in your circular saw, use a wooden surface to press the blade and hold it stable and follow the next step.

Step – 3:

Now you need to use a wrench to rotate the nut to the same direction where the blade turns. It would be best if you had the wrench that comes with the saw when you purchased it.

If it is a direct drive saw, it should be counterclockwise, and if it is a worm drive saw, it should be clockwise. You can slide the blade off after unscrewing the nut.

Step – 4:

Slide the new blade into the arbor and follow the opposite procedure how you unscrewed the previous bade. Place the nut in its place and use the wrench to give it a well-tight.

Remember not to do over-tight and keep in mind; the nut will get tight during the next cutting operation. So, it is better to give quite low tight. Ensure the tight is firm and then you can proceed to the next level.

Step – 5:

Put the battery in its place or plug the cord again. Then, do a trial of whether the circular saw works correctly or not.

Confirm that no additional vibration is there and everything is secured. Once, everything gets a green signal; the circular saw is ready to bite with its new blade.

Final Words

Changing a circular saw blade was never a complicated task. Don’t you think the above steps are straightforward? And you don’t need to sweat your forehead thinking that how will you change your mini circular saw because procedures are nearly the same for all circular saw such as a corded, cordless, standard, or mini circular saw.

Once you change the blade a few times, you will become a PRO undoubtedly.
