Rebar is steel used to reinforce concrete. However, these rods can be used for many other purposes. If you need to cut some rebar down to size, will a circular saw get the job done?

A circular saw can cut rebar with the proper blade. However, there are many other tools you can use for this task if you do not own a circular saw. When using a circular saw or any power tool, keep in mind the safety guidelines for that equipment.

Keep reading to learn more about what circular saws can do and how to use them safely to cut rebar.

Is It Safe to Cut Rebar with a Circular Saw?

A circular saw is a handheld power saw with a round, serrated blade. Instead of sawing back and forth, the blade of the circular saw spins in a circle fast enough to cut through things.

Circular saws come with a blade guard to protect your hands and other materials from getting cut accidentally. However, it is still a dangerous tool. 

Handheld tools like the circular saw offer a lot of flexibility in how they can be used, but with this flexibility comes hazards. It’s important to follow safety guidelines:

  • Circular saws are meant to be used only in one direction. 
  • Push the blade away from yourself.

Now, let’s see if they can cut rebar at all.

Can a Circular Saw Cut Rebar?

A circular saw is one of the more versatile handheld power tools. 

Depending on the size and type of blade you use, you can cut anything from wood to concrete and yes, even steel.

The circular saw can also make a variety of cuts. You can use it for straight cuts, of course, but it works for angled cuts as well.

How Do You Use a Circular Saw to Cut Rebar Safely?

It’s very important to follow safe procedures when using a circular saw, because it can be a very dangerous tool. 

Here are a few safety guidelines to follow when using your saw:

  • Make sure you wear safety equipment like ear and eye protection.
  • Every time you start a new project with the saw, check its components and make sure it is working properly. Check that the blade is sharp and secure and double check the safety guards.
  • It is important to know how to hold the saw properly. The user guide with your saw should explain the best way to hold it, depending on the type you have. 
  • Always push the saw away from yourself and double check that there is nothing in the way of the blade. 
  • When you’re not using the saw, you should turn it off and unplug it. Even if you’re pausing temporarily, powering off and unplugging the saw is still a good idea.

Make sure to check the user guide for your saw to see all the safety guidelines for your specific model.

How Do You Use a Circular Saw to Cut Rebar?

To cut rebar with your circular saw, consider the type of blade you’re using. Cutting steel with a steel blade is possible, but it may damage the blade or reduce its longevity.

Here are some other steps to using a circular saw to cut rebar:

  • A diamond blade is a better option for cutting through rebar. It will cut through the steel faster and there is less of a chance of ruining the blade.
  • Keep in mind also the thickness of the rebar. The thicker the rebar, the bigger the blade you’ll need to cut it.
  • Make sure the rebar is held securely in place. You can do this with clamps. The rebar shouldn’t move at all as you cut it. Double check the rebar is secure before you start to cut it.
  • Watch out for sparks as you make your cut. Make sure nothing flammable is nearby, wear eye protection, and stop immediately if you see smoke or fire.

Now, let’s see what other tools can cut rebar.

What Other Tools Can Cut Rebar?

If you don’t own a circular saw, there are many other tools that can accomplish the job of cutting rebar. Some of these options include a hacksaw, bolt cutter, and miter saw.

A miter saw is similar to a circular saw in that it has a round blade that can cut rebar quickly and efficiently.

However, it isn’t a handheld tool like the circular saw. Instead, the circular blade simply lowers onto what you need to cut. 

A miter saw can offer more stability than a circular saw. Since you can line the rebar up before cutting, it also offers precision. However, it is less flexible in the angles it can cut.


Rebar is not very easy to cut. However, it can be done with the right tools. Both power tools and hand tools can cut rebar if they come with the right blade.

Circular saws are a fast and efficient option. With the right size and type of blade and the proper safe environment, you can easily and safely cut rebar.

Keep following safety protocols with your power tools and you shouldn’t have any issues. Happy cutting!
