The Husqvarna 581058507 Brush Holder is a genuine OEM component designed for the DM280 and DM340 concrete core drills and the K3000 and K4000 power cutters. As a factory-original part, it is manufactured to Husqvarna's exact specifications, ensuring the carbon brushes are held at the correct tension and alignment against the motor's commutator. DHS Equipment supplies this part to help keep your equipment running at full performance.
Key Features
- OEM-Specified Brush Retention — Manufactured to Husqvarna's exact tolerances, maintaining the correct spring tension and contact angle that brush performance depends on.
- Direct Drop-In Replacement — Designed to seat into the motor housing exactly as the original, with no modifications to mounting points or brush pathways.
- Broad Cross-Family Fitment — Compatible with DM280 and DM340 concrete core drills and K3000 and K4000 power cutters, covering two distinct Husqvarna construction equipment families.
- Sustained Motor Efficiency — A correctly seated brush holder maintains consistent electrical contact between the carbon brush and commutator, preserving full motor output and preventing arcing or uneven brush wear.
- Electrical Safety Integrity — A damaged or loose brush holder can cause intermittent arcing and motor overheating; replacing it with a genuine OEM unit restores safe, stable motor operation.
The brush holder is the fixed housing that positions and guides the carbon brushes against the rotating commutator inside an electric motor. It keeps the brushes aligned under consistent spring pressure so that electrical current transfers cleanly and continuously, allowing the motor to deliver its full rated power. When a brush holder cracks, deforms, or loses its retention tension, brushes can sit at an incorrect angle, causing arcing, accelerated brush wear, reduced motor output, and eventual motor failure — making prompt replacement with the correct part essential to restoring reliable operation.
