Dico Products 7200036 Nyalox 4 in Extra Coarse Drill Brush

Product Description

The DICO PRODUCTS 7200036 is a 4-inch Nyalox drill-mounted wire brush designed for surface preparation and finishing work across a wide range of materials. The brush uses nylon bristles impregnated with aluminum oxide abrasive, which allows aggressive material removal without gouging the base surface. It mounts via a 0.25-inch shank, making it compatible with standard drill chucks. The extra-coarse configuration targets rust, paint, corrosion, and burrs on metal surfaces, while finer variants in the Nyalox line handle cleaning and polishing on metal and wood. Tradespeople and maintenance technicians reach for this brush when working in tight crevices or contoured surfaces that flat grinding discs cannot reach.

This brush suits general-purpose surface prep in residential and light commercial maintenance settings. It is well suited for HVAC technicians, plumbers, electricians, and general contractors who need to clean corroded pipe ends, remove rust from brackets or hardware, deburr cut metal, or prep surfaces before fastening or coating. The drill-mount format keeps it accessible without requiring a dedicated bench grinder or angle grinder.
