Circular saw blades need to be changed from time to time to ensure safety. The longer and often it is used, the faster it gets dull and requires changing. It needs replacement when cutting an object takes longer than its usual performance or when it starts making variant or strange sounds while used. Don’t expect its ability to cut will still be the same as the first time using the circular saw blade. One of the reasons why it requires changing is the material to be cut. There are different circular blades to be used for different objects.

How to Change a Circular Saw Blade with These Easy Steps


  • Unplug the power cord from the wall. If it is operated by a battery, remove it. This is to avoid any accidents that may happen when it is turned on accidentally.
  • Push the button that is found on top of the saw. Turn the blade to lock the mechanism connects.
  • Put the wrench on the circular saw arbor nut. Turn the wrench in the direction where the blade cuts to loosen it. The bolt must loosen or else you can’t get the blade off the circular saw. You may also use an impact driver with the correct size socket that fits the nut. It removes faster rather than the wrench where you have to turn it manually. Now, remove the blade by just sliding it down from the arbor to the bottom part of the saw. If the bolt won’t loosen, then the inside of it must be rusted already.
  • Get the blades positioned at the right spot. Get the new blade and put it on the same spot where the old blade was which is onto the arbor. Don’t just put it in any direction you like. Make sure that the blade is correctly placed. The saw teeth of the blade must be in the same direction where the blade will rotate. You may also refer to the blade guard of the saw and look where the arrow is pointing to make sure that the blade is facing the right way.
  • Get the blade wrench you used a while ago to remove the arbor nut. Use it again to tighten back the arbor nut. Do not tighten it too much for you might have a hard time removing it the next time you decide to change the blade again.
  • Finalize using  two wooden blocks and the hammer. Some saws have an arbor that is shaped like a diamond. Put the two wooden blocks over the two ends of the blade to hold it in place. Use the hammer to deliver a blow on the diamond-shaped arbor from the center of the blade. However, not all of the blades are like this. You will just use these tools depending on the blade you have.

Things You Should Keep in Mind


  • Never forget to unplug the power cord or remove the battery before you start changing the saw blade. Always remember this to secure your safety.
  • Follow the instructions on how to change or put a blade on a circular saw step by step, especially if you are a first-timer. Instructions may vary across different brands so this is important.
  • Be careful in taking out and putting the blade back to avoid any cuts.
  • You must have the correct size for every material needed. Everything must fit perfectly to avoid problems of having loose or tight materials.
  • In using the hammer, be careful that you won’t tap it on your hand.
  • If you have any concerns about changing the circular blade, read the instructions again. If you’re still having a hard time, consult a professional instead.
