13K614 - Walter 6-Inch Stainless Steel Stringer Bead Wire Wheel 5/8 Arbor

Precision Cleaning for Stainless Steel Fabrication

The Walter 13K614 is a high-performance 6-inch Stringer Bead Knot Brush designed specifically for the rigorous demands of industrial metalworking. Engineered by Walter Surface Technologies, this brush represents the pinnacle of surface preparation tools, combining durability with precision. The unit features a 6-inch diameter and a standard 5/8-inch arbor, making it compatible with a wide range of angle grinders and stationary bench grinders found in professional fabrication shops. Its defining characteristic is the narrow 1/4-inch face width, which classifies it as a stringer bead brush, optimized for reaching into narrow grooves, channels, and specifically the root passes of pipe welds.

Metallurgy is a critical factor in the performance of this tool. The wire filaments are crafted from high-grade stainless steel (typically 304 grade), which is essential when working on stainless steel base materials. Using carbon steel brushes on stainless steel can lead to "after-rust" caused by embedded iron particles; the 13K614 eliminates this risk, ensuring the integrity of the workpiece's corrosion resistance. The twist knot construction bundles the wires tightly, providing high-impact action that aggressively removes slag, spatter, and heavy oxidation without the flexing associated with crimped wire brushes.

Walter's manufacturing process prioritizes rotational balance. Each 13K614 brush is meticulously balanced to ensure perfect concentricity. This attention to detail results in a tool that runs smooth and true, significantly reducing vibration. For the operator, this means less hand-arm vibration syndrome (HAVS) risk and greater control during delicate cleaning operations. For the machinery, the lack of vibration prevents premature wear on grinder bearings and spindles. Whether used for pipeline construction, pressure vessel fabrication, or general stainless steel maintenance, this brush delivers consistent, safe, and rapid material removal.
