Dewalt DW49057 Stainless Knot Wire End Brush 1in X 1/4in

Product Description

The DEWALT DW49057 is a 1-inch diameter stainless steel knot wire end brush with a 1/4-inch shank, designed for aggressive surface preparation on metal, welds, and hard-to-reach surfaces. Built under DEWALT XP construction standards, this end brush uses .020-inch diameter stainless steel knot wire, which delivers consistent cutting action and extended service life compared to standard wire gauges. It mounts to rotary tools, die grinders, and drills accepting a 1/4-inch shank. HVAC fabricators, pipefitters, and general trades use this type of brush for cleaning weld seams, removing rust, and deburring ferrous and non-ferrous metal surfaces.

This end brush is suited for both shop and field work where a standard cup or wheel brush cannot access tight corners, pipe interiors, or recessed weld joints. The 1-inch face diameter keeps the working area focused, making it practical for tube ends, valve bodies, fittings, and conduit knockouts. It is sold individually and fits any rotary tool or die grinder with a 1/4-inch collet or chuck.
