Product Description ?

Genuine Dewalt replacement part
This brush is sold individually, 2 are needed for the tools shown below
It is always best to replace both brushes, even if only one is worn.

Worn brushes frequently are the cause behind a motor running poorly.
Replacing brushes can fix a motor that’s operating intermittently.
New brushes can restore a motor’s electric braking.

Carbon brushes are one of the most commonly replaced power tool parts. This is because carbon brushes are wear items, meaning that through friction and use they will gradually wear away until they need replacing. Worn brushes are a common causes of intermittent motor function, reduced electric braking and reduced motor power. A worn-out brush will often be worn down near to the wire lead and can be cracked, pitted, or burned. When replacing carbon brushes, be sure to inspect your armature for burns, cracks, or other damage which can indicate larger motor problems.

    the one sent was what was needed.
    I was disappointed in that only one brush was sent. I was sure it was advertised as 2 brushes. Guess I'll know better next time.

    Check the manual on how to take apart, one screw held the housing . One screw each held the brush holder. Removed the wire from the holder, then reinstall the holder, then installed the brushes. Screwed the housing back on, then back to grinding.

    Work safe AND unplug the tool..
