DEWALT Wire Wheel Brush DW4925B 4 Inch 5/8-11 Hub (0.020 Carbon Steel Knot Twist Narrow Stringer Bead Pipe Weld Root Pass Slag Rust Cleaning Unit)

DEWALT DW4925B 4" Carbon Steel Stringer Bead Wire Wheel Brush (5/8"-11 Hub)

The DEWALT DW4925B 4-inch high-performance stringer bead wire wheel brush removes heavy welding slag, oxide scale, corrosion, and stubborn rust from narrow steel seams and restricted metal joints. Constructed with premium 0.020-inch heat-treated high-tensile carbon steel wire arranged in high-density twist knots, this narrow-face brush reaches deeply into narrow V-bevel grooves and pipe root passes where standard wire cups cannot fit. Built with an internal holding plate to minimize knot movement and featuring an integrated 5/8"-11 threaded hub, it equips pipeline welders, structural fabricators, and metalworkers with smooth, low-vibration surface preparation and extended wire life.

Best Used For:

• Pipeline and Pressure Vessel Weld Cleaning: Cleaning slag, carbon buildup, and spatter from narrow stringer beads, root passes, and hot passes in high-pressure pipe welding.
• Tight V-Groove and Angle Joint Deburring: Reaching deep into tight internal corners, structural gussets, and machined channels to remove burrs and oxidation.
• Heavy Rust and Mill Scale Stripping: Scrubbing heavy corrosion, paint coatings, and mill scale from carbon steel beams, plates, and cast iron machinery frames.

Key Performance & Safety Features

• Heat-Treated High-Tensile Carbon Steel Wire: 0.020-inch wire gauge delivers aggressive impact action and resists wire breakage under heavy contact pressure.
• Narrow Stringer Bead Profile: Compact, tightly twisted knot profile fits effortlessly into narrow weld seams, pipe bevels, and tight fillet joints.
• Internal Holding Plate Technology: Stabilizes wire knots to prevent bunching and uneven wire fatigue, ensuring balanced rotation and longer brush life.
• Integrated 5/8"-11 Threaded Steel Hub: Direct-thread mounting enables fast, secure spin-on installation directly onto standard 4-1/2-inch and 5-inch angle grinders.
• Vibration-Damping Balance: Individual knot inspection ensures uniform weight distribution to protect grinder motor bearings and reduce operator hand fatigue.
• Made in the USA: Manufactured to stringent industrial quality and safety standards for demanding commercial and pipeline jobsites.

Technical Specifications

Pro-Tip: When cleaning stringer root passes on pipe welds, let the tips of the 0.020-inch twisted knots do the work with light, steady contact; applying excessive pressure flexes the wire wires against the hub plate, reducing cleaning velocity and causing premature wire breakage.
