Dico Products 7200042 Nyalox 4 in Fine Drill-mounted Brush

Product Description

The DICO PRODUCTS 7200042 is a 4-inch Nyalox fine drill-mounted wire brush designed for cleaning and polishing metal and wood surfaces. The bristles are made from nylon impregnated with aluminum oxide abrasive, which allows the brush to clean and smooth without gouging or scoring the base material. The 0.25-inch hex shank mounts directly into a standard drill chuck, making it a practical handheld or drill-press tool for technicians and tradespeople working on surface prep, corrosion removal, and finish cleaning across a range of materials.

This brush is suited for applications where a fine abrasive action is needed on metal components, pipework, fittings, wood surfaces, or fabricated assemblies. The Nyalox construction is particularly effective in tight crevices and contoured areas where rigid wire brushes cannot reach without risk of surface damage. It is commonly used by HVAC techs, plumbers, electricians, and general tradespeople during surface preparation, light deburring, and pre-weld or pre-solder cleaning tasks.

Key Features

• Nylon bristles impregnated with aluminum oxide for abrasive cleaning without gouging
• Fine grit rating suited for polishing and cleaning metals and wood
• 4-inch diameter provides broad surface contact on flat and contoured workpieces
• 0.25-inch shank mounts directly to standard drill chucks
• Flexible bristle action reaches into tight crevices and complex contours

Compatibility

Designed for use with standard 0.25-inch drill chucks on corded or cordless drills and drill presses commonly used in HVAC, plumbing, electrical, and general mechanical trade applications.

Installation Notes

Secure the 0.25-inch shank firmly in the drill chuck before use and confirm the chuck is fully tightened to prevent slippage. Wear appropriate eye protection and gloves when operating rotary abrasive tools. Inspect bristles before each use and replace the brush if bristles show significant wear or fraying. Follow applicable shop-safety and tool-manufacturer guidelines for maximum RPM ratings.
