The Husqvarna 581086902 Brush Kit is a genuine OEM replacement designed for the DM220 and DM230 concrete core drills. Sourced directly from Husqvarna, this kit ensures the correct carbon brush grade, geometry, and spring tension specified for these drill motors — no guesswork on compatibility. This Brush Kit is a direct-fit replacement for both the DM220 and DM230, restoring full motor commutation and consistent drilling performance. DHS Equipment supplies this part to help keep your core drilling equipment operating at spec.
Key Features
- OEM Carbon Brush Specification — Genuine Husqvarna brushes are manufactured to the exact grade and hardness required for the DM220 and DM230 motor windings, ensuring proper commutation without accelerated wear on the commutator.
- Complete Kit Configuration — Supplied as a matched set so both brushes are replaced simultaneously, maintaining balanced electrical contact and even wear across the commutator surface.
- Confirmed Fitment for DM220 and DM230 — Engineered specifically for these Husqvarna concrete core drill motors, this kit installs directly using the existing brush holders with no adaptation needed.
- Restored Motor Output — Worn brushes cause voltage drop, arcing, and loss of torque at the bit. Replacing them with this kit returns the drill motor to full power and smooth operation under load.
- Electrical Safety Compliance — Using the correct OEM brush grade prevents excessive heat buildup and arcing inside the motor housing, reducing the risk of motor damage and maintaining safe operation on the jobsite.
Carbon brushes are the consumable electrical contact points inside the drill motor that transfer current to the rotating commutator. As the motor runs, the brushes wear down gradually through normal friction, and once they become too short, electrical contact becomes intermittent — causing power loss, increased arcing, motor overheating, and eventual motor failure. Replacing the brushes at the right interval with a correctly specified kit is one of the most effective ways to extend the service life of a core drill motor and maintain consistent performance through heavy drilling cycles.
