09C170 - Walter Allsteel 2-Inch Stainless Steel Crimped Wire Wheel for Die Grinders

Technical Overview of the Walter Allsteel Mounted Wire Brush

The Walter 09C170 Allsteel Mounted Wheel Brush is a specialized abrasive tool engineered for the surface treatment of stainless steel and other non-ferrous metals. Manufactured by Walter Surface Technologies, this brush is defined by its high-grade 304 stainless steel wire filaments. The selection of 304 stainless steel is paramount in industrial environments where surface integrity is critical; using carbon steel brushes on stainless substrates can embed free iron particles, leading to galvanic corrosion and 'after-rust.' This brush eliminates that risk, ensuring compliance with strict passivation and sanitation standards often found in food processing, pharmaceutical, and chemical industries.

Mechanically, the brush features a crimped wire configuration. Unlike knotted wire, which is designed for high-impact aggression, crimped wire offers a degree of flexibility. This allows the filaments to conform to the workpiece's topography, making it an excellent choice for surface finishing, light deburring, and removing heat discoloration without altering the base material's dimensional tolerance. The brush is permanently mounted onto a 1/4-inch steel shaft, ensuring concentricity and balance. This precise balancing is crucial when operating at the tool's maximum rating of 20,000 RPM, as it significantly reduces vibration transfer to the die grinder's spindle and the operator's hand.

The 2-inch diameter provides a calculated peripheral speed that optimizes the cleaning action in confined spaces. It is particularly effective for ID (inner diameter) cleaning of pipes, tubes, and machined bores. The manufacturing process ensures consistent wire density and retention, preventing premature wire breakage and extending the service life of the consumable compared to standard economy brushes. This tool is compatible with pneumatic and electric die grinders accepting a 1/4-inch collet.
