13D314 - Walter 3-Inch Crimped Stainless Steel Cup Brush 5/8-11 Arbor

Precision Surface Finishing with Walter Technology

The Walter 13D314 Crimped Cup Brush represents the pinnacle of surface finishing technology for industrial applications. Designed specifically for use on stainless steel and aluminum, this 3-inch brush is engineered to deliver consistent performance while maintaining the integrity of the base material. At the core of this tool is Walter's commitment to balance and durability. Unlike generic brushes that may wobble or shed wires prematurely, the 13D314 is precision-balanced to run smoothly on angle grinders, significantly reducing vibration. This attention to detail not only extends the life of the power tool by reducing bearing stress but also minimizes operator fatigue during extended periods of use.

The brush features high-quality 304 stainless steel wire with a diameter of .0118 inches. This specific grade of stainless steel is crucial for preventing cross-contamination, a common issue in industrial environments where carbon steel brushes are inadvertently used on stainless surfaces. The crimped wire configuration offers a distinct advantage over knot-twisted alternatives; it provides a degree of flexibility that allows the filaments to conform to slightly irregular surfaces. This makes it an excellent choice for general cleaning, paint removal, and light deburring where a less aggressive, more uniform finish is required. The crimped design acts as a cushion, reducing the likelihood of gouging the workpiece while still effectively removing surface contaminants.

Mounting the brush is effortless thanks to the integrated 5/8"-11 threaded arbor, which fits the vast majority of North American angle grinders. Rated for a maximum speed of 12,000 RPM, this cup brush is capable of rapid material removal, making it a highly efficient tool for MRO (Maintenance, Repair, and Operations) professionals. Whether used in a fabrication shop, a shipyard, or a food processing plant maintenance room, the Walter 13D314 ensures that critical stainless steel components remain clean, passivated, and free from ferrous contamination.
