Product Specification
5" STRINGER BEAD WIRE WHEEL - CARBON STEEL
For welds, grooves, and tight joints where a broad wire wheel wastes contact area, the 5" Stringer Bead Wire Wheel - Carbon Steel concentrates aggressive cleaning power into a narrow working edge. Built with 0.020" carbon steel wire, it is designed for weld-pass cleaning, root-pass work, groove access, and other demanding areas where precision matters just as much as removal speed.
The tightly twisted stringer-bead construction keeps the wire stiff and focused, helping it dig into weld scale, slag residue, oxidation, rust, spatter, and stubborn buildup without brushing a much wider area than necessary. That concentrated action makes it a strong choice for welders and fabricators cleaning between passes or working along narrow joints and structural seams.
Its larger 5" diameter provides more reach and coverage than smaller stringer wheels while preserving the narrow working profile that defines this brush style. A 5/8"-11 threaded arbor provides quick spin-on installation on compatible angle grinders, and the wheel carries a 12,500 RPM maximum rating for properly matched tools.

Applications & Performance
Stringer bead wheels are designed for concentrated cleaning rather than broad surface brushing. Their narrow working edge directs the wire into weld joints, grooves, seams, and other confined areas where wider brushes may be less effective.
Common applications include:
- Cleaning between weld passes
- Root-pass and hot-pass cleaning
- Weld bead cleanup
- Removing weld scale and slag residue
- Spatter cleanup
- Cleaning narrow grooves and joints
- Rust and oxidation removal
- Edge and corner cleaning
- Surface preparation before welding
- Structural-steel fabrication
- Pipeline and maintenance work
The larger 5" diameter gives the operator additional reach while maintaining the focused stringer-bead profile. Use controlled pressure and let the wire tips do the work rather than forcing the wheel into the joint.
Materials
Recommended for cleaning and surface preparation on compatible ferrous materials, including:
- Carbon steel
- Mild steel
- Structural steel
- Cast iron
- Wrought iron
- Other compatible ferrous metal surfaces
Keep carbon steel brushes dedicated to ferrous work when cross-contamination matters. For stainless-steel applications where iron contamination must be minimized, use a dedicated stainless steel wire brush.
Machine Compatibility
Use this 5" wire wheel on a compatible angle grinder with a 5/8"-11 spindle, adequate brush capacity and a maximum speed no greater than 12,500 RPM. Match the actual hub seating and allow room for wire flare.
Compatible examples include:
-
Milwaukee® 2880-20 — 4-1/2" / 5" angle grinder; 8,500 RPM.
-
Milwaukee® 2881-20 — 4-1/2" / 5" angle grinder; 8,500 RPM.
-
Makita® GA7021 — 7" angle grinder; 6,600 RPM.
Other machines may be compatible. Use the manufacturer-specified wire-brushing setup and guard, with secure hub engagement and adequate operating clearance. Other grinders meeting these requirements may also be suitable.
Safety Tips
- Never exceed the wheel's 12,500 RPM maximum speed.
- The wire wheel's rated RPM must meet or exceed the maximum operating speed of the power tool.
- Confirm the grinder is designed to safely accommodate a 5" wire wheel, not simply that it has a matching thread.
- Inspect the brush before every use and replace it if damaged, excessively worn, or improperly mounted.
- Confirm the 5/8"-11 threaded arbor is fully seated and secure before operation.
- Use the appropriate grinder guard and maintain adequate clearance around the rotating wire wheel.
- Wear proper PPE, including eye and face protection, hearing protection, gloves, appropriate clothing, and respiratory protection when required.
- Keep bystanders away from the work area and direction of rotation.
- Use controlled pressure to preserve the wheel's narrow, concentrated working edge.
- Allow the grinder to reach operating speed before contacting the workpiece.
- Follow all operating and safety instructions for both the power tool and wire wheel.
