 How to Install a Blade on a Porter Cable Circular Saw?

If you want to keep your Porter Cable circular saw in good working order, it’s important to change the blade regularly. A dull blade can make it difficult to make clean cuts, and it can also be dangerous. So how do you install a new blade? It’s actually quite simple! Just follow these steps:

 Step By Step Guide:

 Unplug the saw:

The first step is always safety! Make sure to unplug your saw before you do anything else.

 Remove the old blade:

Next, remove the old blade by loosening the arbor nut with a wrench. Once it’s loose, you should be able to pull the blade off by hand. If it’s stuck, you can use a screwdriver to pry it loose.

 Install the new blade:

Now it’s time to install the new blade. Put the blade on the arbor and tighten the arbor nut by hand. Then, use the wrench to tighten it down until it’s snug. Be careful not to over-tighten!

Plug in the saw and test it out:

Now that the new blade is installed, you can plug the saw back in and give it a try. If it’s cutting properly, you’re all set! If not, make sure the blade is installed correctly and try again.

That’s all there is to it! Installing a new blade on your Porter Cable circular saw is a quick and easy process. Just remember to always unplug the saw before you start working, and to be careful when tightening the arbor nut.

 Things to Consider:

  1. Size of the arbor:

Most circular saws have either a 5/8-inch or a 1/2-inch arbor. Be sure to check what size arbor your saw has before purchasing a blade.

  1. Number of teeth:

The number of teeth on a blade will determine how fast it cuts and how smooth the cut is. A blade with more teeth will make a cleaner cut, but it will also cause the saw to work harder and slower.

  1. Material:

The type of material you’ll be cutting will also affect your blade choice. For example, if you’re cutting concrete, you’ll need a different blade than if you’re cutting wood.

  1. Budget:

Don’t forget to consider your budget when choosing a blade. Higher-quality blades will cost more, but they’ll also last longer.

  1. Bonus features:

Some blades come with special features that can make them more versatile or easier to use. For example, some blades have carbide teeth that stay sharp longer, while others have infiltrated teeth

  1. Type of blade (carbide, high-speed steel, etc.):

The type of blade you choose will also affect how well it performs and how long it lasts. Carbide blades are the most expensive but stay sharp the longest, while high-speed steel blades are less expensive but don’t last as long.

  1. Wet or dry:

You’ll also need to decide if you want a wet-cutting blade or a dry-cutting blade. Wet-cutting blades can be used with water to keep the saw and blade cool, but they’re more expensive. Dry-cutting blades don’t require water, but they can overheat quickly.


As with any power tool, there are certain safety precautions that you should take when installing a blade on your Porter Cable circular saw. Make sure to read the saw’s instruction manual thoroughly before beginning the installation process. Also, be sure to wear eye protection and gloves while working with the saw and blade.


Which way do the teeth on a circular saw blade go?

Teeth on a circular saw blade can go in two directions. The most common way for teeth to be oriented is with the teeth pointing toward the center of the blade, but some blades have the teeth pointing away from the center.

How do I know if my circular saw is left or right-handed?

The direction of the blade on a circular saw is determined by whether you are looking at the saw from the front or the back. If the blade is pointing towards the left side of the saw, then the saw is left-handed. If the blade is pointing towards the right side of the saw, then the saw is right-handed.

How do I install a blade on my Porter Cable circular saw?

 To install a blade on your Porter Cable circular saw, first make sure that the saw is unplugged. Next, use a wrench to loosen the bolt that holds the blade in place. Once the bolt is loose, you can remove the old blade and install the new one. Be sure to orient the blade so that the teeth are pointing in the correct direction, and then tighten the bolt to hold the blade in place.

What is the best way to clean a circular saw blade?

Cleaning a circular saw blade is important to keep it working properly and extend its life. One way to clean a blade is to use a brush or cloth to wipe away any debris that has accumulated on the blade. You can also use a vacuum cleaner to remove any dirt or dust from the blade. Another way to clean the blade is to dip it in a solution of soapy water and then rinse it with clean water. Be sure to dry the blade completely before using it again.


Always unplug your saw before installing the blade. Be careful when you handle and install the blade, as they are very sharp. Make sure that the teeth of the blade are pointing in the correct direction before you start screwing it on. Screw the blade onto the arbor until it is tight, but be careful not to over-tighten it. Once you have installed the new blade, plug in your saw and test it out on a piece of scrap wood to make sure that everything is working correctly. Always follow safety precautions when using power tools. If you have any questions, please consult your Owner’s Manual or contact Porter Cable customer service for more assistance.
