Dewalt Accessories DW4902 Knot Wire End Brush 1 Inch

Product Description

The DEWALT ACCESSORIES DW4902 is a knotted carbon wire end brush designed for heavy material removal on metal surfaces. The 1-inch brush head uses 0.020-inch wire diameter and is built with an internal holding plate that maintains wire position during operation, promoting consistent performance and reducing safety risk from wire throw. The 1/4-inch stem arbor fits standard rotary tools and die grinders, and the brush is rated to a maximum speed of 20,000 RPM. Each unit is 100% wire-inspected to meet strict quality specifications. This brush is part of a 5-piece package.

The DW4902 is suited for metal deburring, weld bead cleaning, and surface preparation work in fabrication, maintenance, and repair applications. The knotted wire configuration delivers aggressive cutting action for stripping rust, scale, and heavy coatings from steel and other hard metals. It is a common choice for HVAC installers, pipefitters, and metal fabricators who need consistent bite on tight or hard-to-reach surfaces where a cup brush will not fit. The 1/4-inch stem makes it compatible with most pneumatic and electric die grinders used in trade applications.

Installation Notes

Installation is performed by licensed tradespeople or experienced users familiar with rotary tool safety. Always confirm the tool spindle speed does not exceed the 20,000 RPM rating of the brush before operation. Wear appropriate eye protection and gloves, as wire bristles can throw debris at high speed. Inspect the brush for damaged or missing wires before each use and replace if wire integrity is compromised.
