First things first, you will need to measure the diameter size of your circular blade. Diameter is the measurement starting from the center of the blade up to the sides.

  • Measure the Arbor Diameter – When buying a new circular blade, you will need to know the arbor size of the blade. The measurement starts from the blade’s center hole that should need to fit on the arbor of your circular saw. The arbor size should be visible or printed on the saw. If not, then you will need to measure the diameter of the arbor hole.
  • Measuring the Blade Diameter – Just like the arbor size, the size of the blade diameter should be printed on the blade. The manufacturers purposely print it so you would know your blade’s measurement. If unfortunately, there’s no printed size information, you’ll need to measure it yourself.
  • RPM – You also need to check the RPM or revolution per minute of the blade. This is to ensure that the maximum RPM rate of the new blade will not go beyond the RPM rating of the circular saw. Do this before you start doing any work on your saw.

Different types of circular blade

  • Crosscut Blade is a type of circular blade that contains more teeth. Most crosscut blades may contain more than 40 teeth per blade. You will know if it’s a crosscut because of its V-shaped on the top of the teeth or that forms like a valley shape in the center of the blade.
  • Rip-Cut Blade is another type of circular blade that has fewer teeth compared to crosscut blades. It usually comes with less than 40 teeth per blade, and the teeth are noticeably flat. It’s fairly easy to differentiate each blade since they have different forms from one another.
  • Combination Blade is a type of circular blade which serves its name as it is a combination of either a crosscut or rip cut blade. This is the kind that is used specifically for cutting concrete, metals, and plastics.

Changing the circular blade the right way

  1. Wear Protective Gloves

First things first, wear working gloves to protect your hands. Go to a clear area or to your workshop to conduct the work well.

  1. Unplug the tool from the power outlet

Please take out the saw’s battery or unplug it from the outlet. Make sure you won’t do anything yet until it’s unplugged and powerless. Forgetting to unplug the power outlet might cause accidents and harm, so be extra careful.

  1. Position the blade for installation

Look for the engraved or printed arrow sign from the blade. That should indicate how you should position the blade when installing. The arrow sign should be pointing to the front direction of the circular saw. If there’s no arrow sign available, make sure the teeth are facing towards the front of the saw.

  1. Install the blade

Install the blade in the arbor slot, making sure that the arrow is pointing towards the saw. Then replace the washer and screw as well. When installing the washer and screw, make sure it’s tight enough so it won’t go loose once using it again.

  1. Lock it back in its place

Last but not least, press the blade’s lock and use the wrench again to turn the lock until the blade engages, and the blades stop turning. Press it continuously and turn the wrench counterclockwise until the screw is tight. Check for any loose screws before testing the saw.
