Carbon Brush
Part #N097696
Keep your DeWALT power tools running at peak performance with this genuine OEM carbon brush, sold individually. While two brushes are required for most tools, it's strongly recommended to replace both at the same time—even if only one appears worn—to ensure optimal motor function. Carbon brushes are essential wear components that naturally degrade over time due to friction. Worn brushes are a common cause of poor motor performance, intermittent operation, reduced electric braking, and overall power loss. Signs of wear include brushes that are worn down near the wire lead, cracked, pitted, or burned. Replacing your brushes can restore smooth operation and extend the life of your tool. During replacement, be sure to inspect the armature for any signs of damage such as burns or cracks, which may indicate more serious motor issues. This brush is compatible with a variety of DeWALT tools—check your model for fitment.
