Dewalt DW4902B Wire End Brush Carbon Knot 1 in X 0.25 in

Product Description

The DEWALT DW4902B is a knot-style wire end brush designed for aggressive surface preparation, weld cleanup, and scale removal on metal workpieces. The brush measures 1 inch in diameter with a 0.25-inch shank and is wound with .020 carbon steel wire in a knot configuration. Knot wire construction delivers concentrated cutting action that cuts through rust, mill scale, and heavy oxidation faster than crimped wire alternatives. This tool is installed by fabricators, pipefitters, welders, and general tradespeople who work with angle grinders or die grinders in both shop and field environments.

The DW4902B suits residential and commercial metal fabrication, maintenance, and repair applications. It is used for weld bead cleanup, joint preparation, coating and rust removal from steel pipe, structural steel, and similar ferrous surfaces. The knot wire end configuration allows the brush to reach into tight areas, corners, and pipe ends where flat or cup brushes cannot make full contact. Sold individually.

Key Features

• Knot wire construction for aggressive surface preparation and weld cleanup
• 1-inch brush diameter for concentrated contact on small or recessed surfaces
• 0.25-inch shank for compatibility with standard die grinder and drill collets
• .020 carbon steel wire gauge balances cutting aggression with wire longevity
• End brush profile reaches into corners, pipe ends, and confined areas

Compatibility

Designed as an OEM-style replacement or direct-use wire end brush for die grinders and electric drills accepting a standard 0.25-inch shank accessory.

Installation Notes

A licensed fabricator or qualified tradesperson should install the brush by inserting the shank fully into the grinder or drill chuck and tightening securely before operation. Always confirm the tool RPM rating meets or exceeds the maximum rated RPM of the brush before use. Wear appropriate eye protection and a face shield when operating wire brushes, as wire fragments can break free at speed. Power down and disconnect the tool from the power source before mounting or removing the brush.
