Overview
Replacement carbon brushes restore proper electrical contact between the stationary housing and the spinning armature in brushed power tools. As brushes wear down during normal operation, intermittent sparking, reduced power, and eventual motor failure can occur. These aftermarket brushes are manufactured to OEM dimensions for a precise fit.
Key specifications
- Aftermarket carbon brush replacement
- 8-piece set

Compatibility
These brushes are designed for DeWalt power tools as listed in the compatibility section above. Verify your tool’s model number and brush part number before purchasing to ensure correct dimensions and lead configuration.
Installation notes
Disconnect the power source before servicing. Locate the brush caps on the motor housing, typically held by a slotted cap or Phillips screw. Remove each worn brush and note its orientation, then insert the replacement brush and secure the cap. Run the tool briefly at low speed to seat the new brushes.
Common questions
Q: Will this 650916-01 motor brush set fit my DeWalt D28402 or only the D28 000 series grinders?
Yes, this brush set is made for the DeWalt D28402 and also fits D28 000 series units that use part number 650916-01. It is also listed as compatible with models like D28110, D28112, and DWE46151, but it’s still smart to confirm your original brush part number matches 650916-01 before installing.
Q: My D28110 grinder is sparking and cutting out under load—are these 650916-01 brushes the right fix?
Worn motor brushes are a very common cause of heavy sparking, intermittent power, and weak performance on a D28110. If the commutator is still in good condition and the brush holders are clean, replacing the brushes with this 8-piece 650916-01 set is often the correct repair.
Q: Do I need to do anything special when installing these brushes in a DWE46151 or D28112?
Before installation, unplug the tool and remove any carbon dust from the brush holders so the new brushes can move freely. After fitting them, run the grinder at no load for several minutes to help the new brushes seat properly against the armature.
