13 Amp Vs 15 Amp Circular Saw | Which One Is Better?

When it comes to choosing a circular saw, there are a lot of things to consider. The one thing is 13 amp vs 15 amp Circular saw.

The real difference is the size of the motor, as the amperage (amp) rating refers to the amount of electricity that flows through the motor.

A 15 amp circular saw tends to have more power than a 13 amp one, and this can impact the speed and quality of the cuts you make. so you should pick one based on what type of jobs you’ll be doing.

If you’re looking for a saw that can handle basic woodworking tasks, 13 Amp is Fine.

I personally use BLACK+DECKER for home projects and smaller jobs around my house! But, if you plan on doing more complex tasks, or if you’re working with tougher materials, a 15 Amp saw is a better choice, I recommend getting the SKIL 5280 Model

Which One Is Better | 13 Amp Vs 15 Amp Circular Saw

I’ll take a look at the differences between 13 Amp Vs 15 Amp circular saw, and help you decide which one is best for your needs. Stay tuned!

Choosing the right one of these saws can be tough. A lot of it will just come down to what you need for your projects, but here are some key things to look at when deciding between a 13 amp or 15 amp circular saw:

Cutting capacity

if you’re going to be doing a lot of heavy-duty cutting, it might be worth investing in a saw that has more amps.

A 13 amp saw will have no trouble cutting through a 2×4, while a 15 amp saw will have no trouble cutting through a 4×4.

The difference between the two saws is their rated cutting capacities. A 13 amp circular saw can cut a piece of lumber that is 2-3/8 inches thick, while a 15 amp saw can cut a piece that is 3-1/2 inches thick.

In general, the higher the amperage rating of a power tool, the more powerful it will be.

So if you are regularly cutting pieces of lumber that are thicker than 2-3/8 inches, you would be better off using the 15 amp circular saw.

As I mentioned above, if power is something you’re looking for in your circular saw, then go with the 15 amp option.

It will get through material faster than its smaller brother would (which means less time working and more time relaxing while your machine does all the work).

Size Of Project 

If you’re only going to be cutting smaller pieces of wood (under 2×4), then go with the lighter 13 amp model. However, if you need a saw that’s going to stand up to be used for larger pieces of wood or plywood then go with the 15 amp model.

The Type Of Material 

As I mentioned above in the blade description, it’s worth considering what kind of material you’ll be cutting when choosing between 13 amps and 15 amps circular saws.

If you’ll only be cutting small pieces of wood under 2×4 then go with the lighter model. However, if you’re looking for something that will stand up to more demanding cuts then consider getting a 15 amp one.


Both models of these circular saws are likely to cost just about the same, so your price range should not factor into this decision.

So, is a 13 amp saw good enough for your needs? It depends. If you are cutting through materials that are less than 1-1/2 inches thick, then the answer is yes.

For anything thicker than that, you’ll want to go with the 15 amp model.

Keep in mind that if you are using a power tool for heavy-duty projects, always follow the manufacturer’s guidelines and use the appropriate saw for the job.


What type of maintenance would you need to do?

Typically just oiling your blades each time after use will help keep your saw running smoothly and efficiently.

Most of the time, this maintenance will consist of simply cleaning off any dust that has accumulated on your saw or wiping down the blades with a rag or paper towel to get rid of any debris that may have gotten caught in between them.

Occasionally you may need to replace the part(s) if there has been too much use over time. This is usually only necessary every 2-3 years, though!

What are some common misconceptions about either option?

One misconception is that a 15 amp saw will inherently be more stable than a 13 amp saw. This isn’t true either- both of these models of circular saws have the same amount of stability, and this doesn’t increase as you switch from one to the other.

What are some safety precautions I should take? 

Some safety precautions to take when using a circular saw include:
Wearing appropriate eye and ear protection
Using the correct blade for the material you are cutting
Make sure the blade is sharp and in good condition
Supporting the piece of material you are cutting so it does not kick back or bind
Keeping your hands away from the path of the blade
Use a guide or fence if necessary to help keep the cut straight.
