How Long Do Carbon Brushes Last in Power Tools?

How long do carbon brushes last?

Carbon brushes will usually last between 2 and 10 years in most power tools, depending on how much they are used.

Some brushes can last longer than others all depending on the power of the tool (aka how much wear it puts through the brushes per use). High AH battery powered cordless tools can wear the brushes away really quickly.

On a side note, as the battery technology changes, many cordless tools are changing to brushless formats to combat the need to change parts so regularly.

Signs of Wearing Carbon Brushes

The classic signs your brushes are ready to be replaced are:

  1. More Sparks Than Usual - a little sparking is normal, but if it's gradually getting worse then it is a sign of wearing brushes.

  2. Drops in Performance - if the tool is losing RPM and general performance, then it's a sign of the carbon brushes wearing out.

  3. Burning Smell - the increased friction of the worn brushes will cause a burning smell.
