Time to change your Carbon Brushes?

There are many different working parts within your power tools such as switches or carbon brush caps and that can often make it difficult to identify which part of your power tool is causing the problem.

With so many working parts, it is inevitable that things will go wrong and whether that is through a fault or heavy use, it is important that you can identify where the problem lies. One area of your power tool that can cause problems is the carbon brushes and when the time comes to replace them, you need to know that they are causing your power tool problems.

The Importance of Carbon Brushes

Whether you use a Makita power tool or any other kind of power tool, there is a wide range of Carbon brushes out there such as the Titan TTB280DRH Carbon Brushes or the Carbon Brushes for TITAN TTB278SDS. However, the carbon brushes are essentially the main feature of your power tool. They might be small but they are extremely vital to the motor of your power tool. The carbon brushes will bring all of the components of your power tool together so that it can work at its absolute peak. The carbon brushes work exceptionally hard and they will keep on working until they begin to wear. Over time, they will wear down and with that, the performance of your power tool will begin to diminish. However, identifying when that time comes can prove difficult, but spotting the signs early can help you to get them replaced quickly while preventing further damage to your motor and your power tool.

When Do They Need Replacing?

One of the first things you will notice is that your power tool won’t be performing in the way that you are used to. As a result, you might have to shake your power tool in order to get it moving while it will certainly lose its ability to produce the high RPMs that you are used to. This will result in a loss of energy and ultimately power.

Another common sign is a smell of burning as this can indicate that the carbon brushes are now completely worn, with the burning smell coming from friction within your power tool.

What might shock you and concern you is the sparking that might occur. It is common for sparking to happen in a power tool but once the carbon brushes begin to wear down, you will notice that this happens more frequently. You will notice the sparking through the cooling vents of your power tool, and this handy cooling vent actually makes it possible for you to keep an eye on the sparking, enabling you to determine whether it is getting worse or not.

Along with this, you might find that your power tool eventually gives up by stalling or cutting out while you are using it. This is a clear sign that your carbon brushes
have completely worn out and are in need of replacing.

Why You Should Actively Maintain Your Carbon Brushes

Your power tool might be something you use at home or it might be something that you use for your job on a daily basis, whatever it might be, you should consider actively maintaining your power tools. While it is acceptable to let your power tools show you that it is time to replace the carbon brushes, it is not always the right thing to do.

There is no need to check the tool on a daily basis but every now and again, it can help to take a look at the carbon brushes to make sure that they are looking good and fit for purpose. A good rule of thumb to work to is to monitor the carbon brushes until they are worn down to around a quarter of an inch, as this is usually a good time to replace them. If the brush displays signs of breakage, crumbling or burning then it should be replaced while any changes in colour to the spring such as rainbow patterns, could indicate that there is a broken lead in the spring. Also, if the spring has collapsed, then that will mean that the carbon brushes will also need replacing.

Change you carbon brushes or risk damaging your Armature

So, you should not leave worn carbon brushes inside your power tool for too long as this can damage the armature which is a costly repair itself. Therefore, keep an eye out for the clear signs of underperforming power tools, bad smells and sparking as this will indicate that the carbon brushes need replacing.
