Your power tool is on the blink, and you’re wondering if it’s the carbon brushes again.
So in this post, we’ll go over the top symptoms of faulty or worn carbon brushes, and how to fix or replace them.
1. Worse Power Tool Performance
If it’s the early stages of your carbon brushes failing, then you’ll start to notice a decline in tool performance over time.
The drill won’t quite get up to speed, or you may have to shake it to get it going to full power.
2. Burning Smell from Tool
Another very common sign of a carbon brush on the edge is a burning smell from the tool. This can occur just after the tool has been used as well, and it’s a bad sign that the brushes are completely worn away, creating friction between moving parts.
3. Sparks from Tool
Some sparking in power tools is common, but large sparks are not. You can check the cooling vents of your tool to see the sparks, and doing this early on will help you monitor if things are getting worse.
4. Keeps Cutting Out
One of the most frustrating signs of the brushes wearing out is the tool cutting out completely. This can be very frustrating, and even dangerous on some jobs, so this will often be the final straw when it comes to replacing the brushes.
Can you Fix Carbon Brushes or Do They Need Replacing?
It’s not possible to fix carbon brushes, as the carbon has been worn away in most cases, so there’s nothing left to conduct. You can’t use carbon found in batteries or other “quick tips” you might see online, as it’s the wrong material and could be damaging.
