The DICO PRODUCTS 7200025 is a 3/4-inch Nyalox drill-mounted wire brush designed for spot cleaning and accessing hard-to-reach areas on metal surfaces. The brush uses nylon bristles impregnated with aluminum oxide abrasive, an extra coarse configuration that removes weld scale, rust, old paint, and oxidation without gouging the base material. It mounts via a 1/4-inch shank and is driven by a standard power drill or drill press. This tool is well suited for HVAC technicians, plumbers, pipefitters, and general maintenance trades who need fast, controlled surface prep in tight spaces.
The 7200025 is used in applications where surface preparation is required before welding, coating, or reassembly. Its compact 3/4-inch diameter allows work inside fittings, around pipe joints, and in confined equipment cavities where a larger wheel or cup brush cannot reach. The aluminum-oxide-impregnated nylon construction makes it appropriate for use on ferrous and non-ferrous metals where a wire brush might leave embedded steel particles or cause unwanted scoring.
Designed for use with any standard power drill or drill press accepting a 1/4-inch round shank accessory.
Secure the 1/4-inch shank firmly in the drill chuck before operation and confirm the chuck key is removed. Wear appropriate eye protection and gloves, as bristle fragments and debris are ejected during use. Operate within the maximum RPM rating of the brush and the drill to prevent bristle failure. This is a hand-tool accessory and does not require licensed trade installation, but standard shop safety practices apply.
