Milwaukee Brush Card Assembly
Model Number: 14-46-2012
The Milwaukee 14-46-2012 is a genuine OEM Brush Card Assembly replacement for compatible Milwaukee power tools — a service assembly containing the carbon brush, holder, and associated card or mounting structure as an integrated replacement unit for tools that use the brush card assembly design. The brush card assembly integrates the carbon brush's electrical and mechanical elements into a single service component that mounts directly to the tool's field housing at the designated brush position, providing the correctly oriented brush contact with the armature commutator through the card's geometry and mounting interface. This design simplifies field and shop service by providing the complete brush assembly including the mounting structure in a single OEM-sourced part, ensuring that the brush is correctly oriented, the spring tension is set to the correct specification, and the card mounting positions the brush at the correct commutator contact angle for consistent performance after installation.
Carbon brushes are the primary consumable wear component in brushed electric motors — replacing the brush card assembly at the correct service interval before complete brush wear maintains motor performance and prevents armature commutator damage from arcing that occurs when brushes wear through to the spring or card end. Most Milwaukee brushed motor designs use two brush card assemblies, one on each side of the armature, and both should be replaced simultaneously when either requires service to maintain balanced electrical delivery. Always verify your specific Milwaukee tool's model number and serial number at milwaukeetool.com or reference the service parts diagram to confirm the correct brush card assembly part number before ordering.
