Key benefits Flexible nylon bristles clean, deburr and lightly sand without cutting into or damaging the underlying surface. Multiple grit options (80–320) let you move from aggressive material removal to fine finishing with the same wheel design. Bristle-side design conforms to holes, grooves, edges and other hard-to-reach areas for consistent results on irregular surfaces. 6 mm (1/4") shank fits common drill and rotary tool chucks for fast attachment and stable operation. What this brush solves Removes rust and loose paint from metal and prepares metal or wood surfaces for painting without excessive substrate removal. Reaches into concave wood grain, grooves and corners where flat sandpaper or rigid wheels cannot. Cleans and refines delicate furniture surfaces (e.g., mahogany, layered finishes) while preserving the shape and detail. Specifications Material: nylon bristles suitable for wood, metal, plastic and stone Wheel diameter: 83 mm / 3.27" Wheel thickness: 35 mm / 1.38" Shank diameter: 6 mm / 1/4" Shank/handle length: 70 mm / 2.76" Grit options: 80, 120, 180, 240, 320 Typical applications Rust and paint removal from flat metal panels before repainting. Fine sanding and grain enhancement on mahogany furniture and three-layer wood surface finishing. Trimming, grinding and polishing uneven or side surfaces, such as inside grooves, molded edges and recessed details. Usage notes Select coarser grits (80–120) for faster material removal, then switch to finer grits (180–320) for smoothing and finishing. Operate at moderate speed and light pressure to avoid heat buildup and to let the bristles conform to the surface. Fits tools that accept a 6 mm / 1/4" shank; ensure secure mounting before use.
