DeWalt N398321 Genuine OEM Carbon Brush Set (2 Pack)

The DeWalt N398321 Carbon Brush Set is a genuine OEM replacement designed to restore power and performance to compatible DeWalt polishers. Motor brushes naturally wear over time due to friction during operation. When brushes become worn, tools may experience reduced power, inconsistent operation, or difficulty starting.

Replacing worn carbon brushes is a simple maintenance step that helps extend the life of your polisher and keep it running at peak performance. Manufactured to DeWalt’s exact specifications, these OEM brushes ensure proper fitment, reliable electrical contact, and long-lasting durability.

Each package includes two replacement carbon brushes, allowing you to service both sides of the motor as recommended.

When installing new brushes, it is also good practice to inspect the armature and commutator for signs of excessive wear or damage that may affect motor performance.
