OVERVIEW

Genuine Walter Surface Technologies Replacement Components

The Walter 48M474 Carbon Brush Set is a critical maintenance component designed specifically for Walter electric power tools. Carbon brushes are the electrical link between the power source and the rotating armature of the motor. Over time, friction and electrical arcing cause these brushes to wear down. Utilizing genuine OEM parts like the 48M474 ensures that the replacement brushes possess the correct carbon density, conductivity, and spring tension required by Walter's high-performance motors.

Failure to replace worn brushes can lead to poor motor performance, intermittent operation, and eventually, severe damage to the commutator. This set is engineered to meet the exact specifications of tools such as the Walter Mini-Grinder and Big Buff III, ensuring a precise fit and reliable operation. The high-quality carbon compound used in these brushes minimizes sparking and heat generation, thereby protecting the tool's internal components and prolonging its operational lifespan.

Maintenance professionals understand that using aftermarket or incorrect brushes can result in rapid wear or motor failure. This genuine Walter set restores the tool's original torque and speed characteristics, making it an essential item for any MRO inventory supporting Walter equipment.

Common signs include a loss of tool power, the tool cutting out during use, or excessive sparking visible through the cooling vents. If the brushes are worn down near the wear limit line, they must be replaced.

The 48M474 is sold as a set (pair), as both brushes in the motor should always be replaced simultaneously to ensure even wear and performance.

No, these are designed specifically for Walter Surface Technologies tools. Using them in other brands may result in poor fitment or motor damage.

This set is primarily compatible with Walter electric tools such as the Mini-Grinder and Big Buff III. Always check your tool's parts diagram to confirm the part number.

Yes, on most Walter tools, the brush caps are accessible externally or by removing the rear housing. Ensure the tool is unplugged before attempting any maintenance.

OEM brushes have the specific hardness and resistance values engineered for the motor. Generic brushes may be too hard (damaging the commutator) or too soft (wearing out quickly).

Yes, the carbon brush assembly typically includes the necessary spring and lead wire connection for proper installation.
