OVERVIEW

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.

FAQ

This brush features a standard 5/8"-11 threaded arbor, compatible with most 4.5-inch and 5-inch angle grinders.

While it will physically work, it is not recommended. Using a stainless brush on carbon steel is a waste of the more expensive stainless wire, and if you later use the same brush on stainless steel, you will transfer carbon contaminants back onto the stainless, causing rust.

The maximum safe operating speed is 12,000 RPM. Always ensure your grinder's no-load speed does not exceed this rating.

Crimped wire is more flexible and less aggressive, making it better for light cleaning, surface finishing, and working on larger flat areas without digging into the metal. Knot wire is for heavy-duty impact and scale removal.

Yes, the stainless steel wire is compatible with aluminum and will not cause rust or ferrous contamination, making it excellent for cleaning aluminum oxide before welding.

The wire diameter is .0118 inches, which provides a good balance between stiffness for cleaning and flexibility for finish quality.

No, this is a cup brush with an integrated arbor. It screws directly onto the spindle of your angle grinder.

Use the lightest pressure possible. Let the tips of the wire do the work. Excessive pressure bends the wires, causing fatigue and premature breakage.
