Dewalt Accessories DW4920 Crimp Cup Brush 3 in 5 Pack

Product Description

The DEWALT ACCESSORIES DW4920 is a 3-inch crimp cup brush built for heavy-duty surface preparation on ferrous metals. Constructed from carbon steel wire, it mounts via a 5/8-11 arbor and attaches to angle grinders and compatible rotary tools used in metal fabrication and maintenance work. An internal holding plate retains the wire fill throughout the work cycle, improving both operator safety and brush consistency over repeated use. This SKU is packaged in a quantity of 5, making it well suited for shop stocking or multi-job fieldwork. Licensed tradespeople and fabricators who need reliable wire tooling for repetitive surface work will find this brush a dependable bench-stock item.

The DW4920 is suited for applications including metal deburring, weld bead cleaning, rust removal, paint stripping, and edge blending on ferrous surfaces. It performs in light fabrication shops, HVAC mechanical rooms, structural steel work, and general maintenance environments where an angle grinder is the primary tool. The 3-inch diameter fits within tight contours while still covering enough surface area to move efficiently across flat stock, pipe, or structural shapes. The 5-pack format reduces per-unit cost for contractors who cycle through cup brushes regularly on production or restoration work.

Installation Notes

Cup brushes of this type are installed and serviced by machinists, fabricators, pipefitters, and general maintenance tradespeople. Before mounting or removing the brush, disconnect or power down the grinder completely. Thread the brush onto the 5/8-11 arbor in the direction that tightens under load, and verify the brush is fully seated before operation. Always wear appropriate PPE including face shield and gloves, and observe the maximum RPM rating of the tool to avoid wire ejection.
