Product Specification
4" STRINGER BEAD WIRE WHEEL - CARBON STEEL
When the job is down inside a weld joint instead of spread across a broad surface, the 4" Stringer Bead Wire Wheel - Carbon Steel puts aggressive cleaning power exactly where you need it. Built with 0.020" carbon steel wire, its narrow stringer-bead profile is designed for concentrated weld-pass cleaning, root-pass work, grooves, corners, and other areas where a wider wire wheel cannot reach as effectively.
The tightly twisted wire construction creates a stiff, focused working edge that cuts through weld scale, slag residue, oxidation, rust, spatter, and stubborn deposits without unnecessarily brushing a wide area around the weld. That makes it especially useful for welders and fabricators who need precise cleaning between passes or along narrow joints.
A 4" diameter keeps the wheel maneuverable, while the 5/8"-11 threaded arbor provides quick spin-on installation on compatible angle grinders. With a 20,000 RPM maximum rating, this is a purpose-built wire wheel for fabrication shops, structural work, maintenance, repair, and demanding weld-cleaning applications.

Applications & Performance
Stringer bead wheels are designed for focused cleaning rather than broad-area brushing. Their narrow working edge concentrates the wire directly into welds and grooves where wider wheels can be less effective.
Common applications include:
- Cleaning between weld passes
- Root-pass and hot-pass cleaning
- Weld bead cleanup
- Removing weld scale and residue
- Slag and spatter cleanup
- Cleaning narrow grooves and joints
- Rust and oxidation removal
- Edge and corner cleaning
- Surface preparation before welding
- Structural and pipeline maintenance
- Cleaning fabricated steel assemblies
For best performance, position the narrow working edge where cleaning is needed and let the wire tips do the work. Excessive pressure can spread the wire, reduce the focused cleaning action, and accelerate brush wear.
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 fabrication where iron contamination must be minimized, use a dedicated stainless steel wire brush.
Machine Compatibility
Use this 4" wire wheel on a compatible angle grinder with a 5/8"-11 spindle, adequate brush capacity and a maximum speed no greater than 20,000 RPM. Match the actual hub seating and allow room for wire flare.
Compatible examples include:
-
Benchmark Abrasives BMT-AGBC4570_1 — 4-1/2" corded angle grinder; 5/8"-11 spindle; 11,000 RPM.
-
Makita® 9557PB — 4-1/2" angle grinder; 11,000 RPM.
-
Milwaukee® 2880-20 — 4-1/2" / 5" angle grinder; 8,500 RPM.
-
Milwaukee® 2881-20 — 4-1/2" / 5" angle grinder; 8,500 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 20,000 RPM maximum speed.
- The wire wheel's rated RPM must meet or exceed the maximum operating speed of the power tool.
- 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.
