Dewalt DW4902 Knot Wire Wheel Brush 1 in Carbon Steel

Product Description

The DEWALT DW4902 is a 1-inch knot-style wire wheel brush designed for aggressive surface preparation and cleaning on metal, welds, and castings. It features a carbon steel wire construction with a 0.020-inch wire diameter and a 1/4-inch hex stem for direct chuck mounting on standard drills and die grinders. The knot configuration delivers concentrated abrasive action, making it effective for removing rust, scale, paint, and weld spatter. This brush is a single-unit consumable tool used by tradespeople across mechanical, fabrication, and maintenance work.

The DW4902 is suited for use in light industrial and field maintenance applications where a compact, chuck-mounted wire brush is needed. Its 1-inch diameter makes it appropriate for work in confined areas, tight corners, and small weld joints where larger cup or flap brushes cannot reach. Typical users include pipefitters, welders, HVAC technicians, and general maintenance mechanics who need a fast, tool-driven cleaning solution without a bench grinder or angle grinder setup.

Key Features

• Knot wire construction for aggressive rust, scale, and paint removal
• Carbon steel wire at 0.020-inch diameter for durability and bite
• 1-inch brush diameter suited for confined and detail work
• 1/4-inch hex stem mounts directly to standard drill chucks and die grinders
• Single-piece unit sold individually for targeted replacement

Compatibility

Designed as an OEM-style accessory for use with standard 1/4-inch chuck drills and die grinders compatible with hex-shank wire wheel brushes.

Installation Notes

Installation is performed by inserting the 1/4-inch hex stem directly into the tool chuck and tightening securely before operation. Ensure the tool is powered off and unplugged or battery removed before mounting or removing the brush. Operators should wear appropriate eye protection and gloves, as wire bristles can shed during use. Follow all applicable ANSI and tool manufacturer safety guidelines for rotary wire brush accessories.
