The Husqvarna 589910402 Brush Holder is a genuine OEM component designed for the DM220 concrete core drill. Sourced directly from Husqvarna, this part meets the exact specifications of the original, ensuring the motor's carbon brushes are seated and retained correctly. DHS Equipment supplies this part to help keep your core drilling equipment performing at its best. Cross-reference part number 589910402 against your parts diagram to confirm fitment before ordering.
Key Features
- Genuine OEM Brush Retention — manufactured to Husqvarna's exact dimensional tolerances, ensuring the carbon brushes make consistent, stable contact with the motor commutator.
- Direct OEM Replacement — engineered as a drop-in replacement for the original holder, aligning precisely with the motor housing mounting points on the DM220.
- DM220 Concrete Core Drill Fitment — purpose-built for the DM220 drill motor, so you can order with confidence that this is the correct component for your machine.
- Restored Motor Efficiency — a damaged or worn brush holder causes uneven brush wear, arcing, and power loss; replacing it restores steady electrical contact and full motor output.
- Electrical Safety Compliance — correct brush alignment and secure retention reduce the risk of arcing, overheating, and premature motor failure in a high-demand drilling environment.
The brush holder is a structural component inside the electric motor that positions and guides the carbon brushes against the spinning commutator, maintaining the electrical contact needed to drive the motor. When the holder cracks, deforms, or loses its retention tension, the brushes shift out of alignment — causing excessive sparking, uneven brush wear, reduced drilling power, and ultimately motor damage. Replacing a faulty brush holder promptly protects the motor and keeps the DM220 drilling at full capacity.
