What is the purpose of a circular saw electric brake?

The power source and design aren’t the only things to look for when buying a circular saw. For safe and efficient operation, it is crucial to check and understand its features. Ever wondered what is the purpose of a circular saw electric brake?

An electric brake is activated by releasing the circular saw trigger. When activated the electric brake reverses the electricity flow and stops the blade almost instantly. It makes the saw safer as the blade is quickly stopped from spinning soon after the trigger is released.

This feature is often very underrated, although it can be life-saving in some situations.

These are my top circular saw (with electric brakes) picks:

What is a circular saw?

If you want to start with woodworking, a circular saw is the first tool you need to consider. This power tool uses a blade that spins around an arbor and you can use it for straight cuts.

However, this tool has many features that make the cutting easier and productive. In this article, I will only stick to one of the systems that people often forget to mention.

The circular saw electric brake mechanism

The science behind this feature is not so difficult to explain – you just pull the trigger and the blade stops much faster than it would stop when it is left on its own. A simple process that brings many advantages.

I guess that the engineers that build this system probably won’t agree that it is a simple feature, however, for you as an operator, there is nothing more you should worry about.

How long does it take the circular saw blade to stop spinning?

Every model is different, but generally, it would take up to 12 seconds for the blade to stop spinning after you have finished the cut. That seems like a short period, but for that time the blade could damage the material or even cause an injury.

And how many long does it take to stop a circular saw blade with an electric brake?

Only 2 seconds, which is 6 times less. This makes it a lot safer and means that you can save waiting for up to about 10 second per cut for the saw to stop spinning before putting it down.


Why is the electric brake so important?

Manufacturers came up with many other solutions – shaft locks, bevel stops and so on. Why is the electric brake so important? Is it just about the safety?

I wouldn’t say so.

  • Safety

Safety should always be your first priority – especially when you are playing with big toys like the heavy-duty circular saw.

For that reason, manufacturers often various features in order to increase the safety of the operator and electric brake is one of their very best.

Forget about damaging the blade or the material (even though those could cost you much) – the electric brake could save your fingers and that is way more important.

However, this feature won’t help much if you don’t follow the rules and use the circular saw in a right way.

  • Productivity

Imagine that you are cutting wood and you need to wait until the blade stops spinning so you can make another cut. Occasional cutters may won’t experience this problem, but for professionals that make hundreds or thousands of cuts, this could be time-consuming.

Not only that is a safety feature, the electric brake can be a productivity booster, as the time between two cuts can be reduced dramatically.

Once you finish the cut, pull the trigger that activates the electric brake and start your next cut sooner.

My circular saw recommendations

Many manufacturers implement this feature in their models. I did a research and there are several models from the most famous power tools companies that you should definitively consider.
