It’s 2021 and people are still changing the dull blades of their circular saw, and it’s a shame. You can always sharpen the dull blades and restore them to their former glory, that too with a bit of effort. You can save a lot of money here.
So, if you’re willing to put in a bit of hard work so that you can save some of your time and money, then you should stick to this article. Now, we’ll discuss how to sharpen a circular saw blade.
Tools that You’ll Need:
You need the following tools to sharpen the blade of a circular saw:
- Screw clamps
- Ring Spanner
- Flat file
- A set of pliers
- Triangular file
Once you have these, you can get started on sharpening the blades. However, you need to remember that the blades can only be sharpened if they aren’t specially hardened. The specially hardened blades come with a layer that’s equally tough as the tools used to sharpen them, which makes this process impossible. So, you better lookout for that.
How to Sharpen A Circular Saw Blade?
These are the steps that you need to follow to sharpen the blades of a circular saw blade:
- At first, you’ll need to remove the blades for sharpening them. If you have an old circular saw, then chances are that you’ll have to wrench the bolts to remove the blades. On the other hand, if you have a newer circular saw, then you might have a blade release switch. Needless to say, the newer versions are much easier to handle.
- Once the blade is removed, you need to secure that in one place using a vice grip. However, we advise you not to tighten the vice too much, as it may bend the blade.
- Just put a mark on a single spot on the blade, and make sure the marks at the top. This will act as a milestone and it’ll help you understand when you’ve covered the entire blade. Otherwise, you might end up double sharpening which is bad for the blade.
- Most blades come with bevel edges, so you need to ensure that you sharp the same side on all the edges.
- Once you’ve performed the steps from one side, you need to flip the blade and repeat all the mentioned processes.
- File the tip of all the teeth on the blades. Don’t apply too many strokes as you may end up overdoing it. Applying it a few times is enough.
- Once you’re done with all of these steps, you’re going to have a completely resharpened blade. All that’s left to do now is to install the blades on the saw.
If you follow the steps that we’ve mentioned above properly, you’ll be able to resharpen and reuse the saw blades properly. We highly recommend checking whether your blade is hardened or not. If it is, there’s no other way than to change the blades.
