If I answer it simply, then yes, you can. Now, the long answer is much more complicated and I would have it break down why is it possible to use a smaller blade and what are things you’ll need to consider before using one.
So, if you are still wondering can you use a 7 blade on a 7-1/4 saw, then mate check out the sections down below to know what you are going into.
Why I don’t suggest people use a smaller blade is because it’s a bit risky. The gap between the blade and the saw should not be more than 1/8-inches. However, if you are not concerned about safety or having something else to protect you and your workplace from, then you can use a smaller circular saw blade.
Usually, what matters the most is the arbor size. If the arbor size matches your saw, then chances are you will be able to continue working with a smaller blade. Hence, the first thing you’ll need to check is the arbor diameter of your blade and saw.
It won’t matter if your blade is 7 or 7-1/4-inch unless the intended geometry of the blade is compatible with the model or type of saw you are using. For instance, some blades even if they are of the right size cannot be used with certain saws. This usually happens in the case of miter saws because the angle of teeth is considerably different in those.
You will also need to check if the max rpm, kerf, and blade width are suitable for the saw you are using.
The cutting depth reduces when you are using a 7-inch blade on a 7-1/4-inch saw. Therefore, you need to adjust the blade in order to cope up with the reduction.
The overall build or the nature of a miter saw confines this reduction in size. You will not be able to make cuts if there is any more reduction. It also makes the blade susceptible to wear as you won’t be able to do anything about the reduced cutting depth.
Final Piece of Advice
Whether you are using a miter, table, or circular saw, it is best not to use a blade that is smaller in diameter. Even if the difference is only ¼-inches, why take the risk?
In any case, if you are going to use a smaller blade, I would recommend that you use a saw that is capable of adjusting. The best circular saws on the market are more versatile, which reduces the risk of accidents around the workplace.
I hope you got your answer to can you use a 7 blade on a 7-1/4 saw. Now what you do next is totally up to you. Good luck!
