09C020 - Walter Allsteel 1-1/8" Knot Twist Wire End Brush with 1/4" Shank

Walter Allsteel 09C020 Mounted End Brush Overview

The Walter Allsteel 1-1/8" Mounted End Brush (SKU: 09C020) is a high-performance abrasive accessory designed for industrial surface preparation and finishing. Engineered by Walter Surface Technologies, this brush is part of the ALLSTEEL™ collection, which is renowned for providing excellent value without compromising on safety or durability. The brush features a knot-twisted wire configuration, which bundles the wire filaments together to create a stiff, aggressive tip. This design is significantly more impactful than crimped wire alternatives, making it the ideal choice for heavy-duty applications where surface contaminants are stubborn or deeply embedded.

One of the standout features of this product is its precision balancing. Unbalanced brushes can cause severe vibration in high-speed tools like die grinders, leading to premature tool wear and operator fatigue (often referred to as "white finger"). Walter manufactures these brushes with meticulous attention to wire count and distribution, ensuring smooth, vibration-free operation even at the maximum rating of 20,000 RPM. The 1/4" steel shank is robust and fits securely into standard collets, providing a safe and concentric rotation.

The wire material itself is high-grade carbon steel, specifically tempered to resist fatigue and breakage. This ensures that the brush maintains its cutting action over a longer service life compared to generic alternatives. The 1-1/8" diameter is specifically sized to enter recesses, bores, and corners that larger cup or wheel brushes cannot reach. Whether you are removing heavy rust, scale, or preparing a surface for coating, the 09C020 delivers consistent, professional results. It is an essential consumable for MRO (Maintenance, Repair, and Operations) environments, metal fabrication shops, and industrial manufacturing facilities working primarily with steel components.
