OVERVIEW

Maintain Peak Performance with Genuine Walter Replacement Parts

The Walter 48H346 Carbon Brush Set is an essential maintenance component designed specifically for Walter Surface Technologies' line of high-performance 120V power tools. Carbon brushes are critical electromechanical parts that conduct electrical current between the stationary wires and the rotating wires of the motor's armature. Over time, friction and electrical arcing cause these brushes to wear down, which can lead to intermittent power loss, sparking, and eventually, complete motor failure. This set includes two precision-engineered brushes to perform a complete replacement on your compatible device.

Designed for industrial durability, these brushes are compatible with popular Walter finishing tools such as the Big Buff III and the Line-Mate III. Using genuine OEM parts is crucial for maintaining the warranty and safety standards of your equipment. Generic brushes may use inferior carbon compounds that wear too quickly or, worse, are too hard and score the copper commutator bars of the armature, leading to expensive repairs. The 48H346 set ensures the correct spring tension and contact surface area for optimal electrical transmission.

Regular inspection of carbon brushes is a standard preventive maintenance procedure for any brushed universal motor. If you observe excessive sparking through the tool's vents, experience a loss of torque under load, or if the tool fails to start, it is likely time to replace the brushes. This kit provides a cost-effective solution to extend the lifecycle of your premium surface finishing tools, ensuring they continue to deliver the consistent speed and power required for professional metalworking applications.

FAQ

These brushes are primarily designed for Walter Surface Technologies 120V finishing tools, specifically the Big Buff III and Line-Mate III models. Always check your tool's parts diagram to confirm compatibility.

Common signs include excessive sparking visible through the tool's vents, intermittent power or stalling during use, and a decrease in tool performance. If the brushes are worn down near the wear limit line, they should be replaced.

Yes, typically Walter carbon brush assemblies like the 48H346 come with the necessary springs and leads attached for a drop-in replacement.

It is highly recommended to replace both carbon brushes at the same time to ensure even wear and consistent motor performance. This set includes two brushes for this purpose.

Yes, this is a genuine Original Equipment Manufacturer (OEM) part from Walter Surface Technologies, ensuring the highest quality and correct fitment.

No, these are specified for 120V models. 240V tools typically require different brushes with different resistance properties. Check your tool's voltage rating before ordering.

For tools used daily in industrial environments, it is good practice to inspect the brushes every 2-3 months or every 100 hours of operation.
