Product Specification
4" STRINGER BEAD WIRE WHEEL - STAINLESS STEEL
For stainless welds, grooves, and tight joints that need aggressive cleaning without introducing carbon steel wire to the workpiece, the 4" Stringer Bead Wire Wheel - Stainless Steel puts concentrated brushing action exactly where it is needed. Built with 0.020" stainless steel wire, its narrow profile is designed for weld-pass cleaning, root-pass work, groove access, and other areas where a wider wire wheel can be too broad.
The tightly twisted stringer-bead construction creates a stiff, focused working edge that attacks weld scale, oxidation, discoloration, residue, rust, and other stubborn deposits while limiting unnecessary contact with the surrounding surface. That makes it especially useful for stainless fabrication where both aggressive cleaning and precise control matter.
A compact 4" diameter keeps the wheel maneuverable around weldments and fabricated assemblies, 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 stainless wire wheel for welders, fabricators, maintenance crews, and repair shops that need focused cleaning power in narrow areas.

Applications & Performance
Stringer bead wheels are made for focused cleaning in narrow areas, not broad surface brushing. Their concentrated working edge gets directly into weld joints, grooves, and tight transitions where a wider brush may not clean as effectively.
Common applications include:
- Cleaning between weld passes
- Root-pass and hot-pass cleaning
- Stainless weld bead cleanup
- Removing weld scale and residue
- Oxidation and heat-tint cleanup
- Cleaning narrow grooves and joints
- Rust and corrosion removal
- Edge and corner cleaning
- Surface preparation before welding
- Structural and fabrication maintenance
- Cleaning stainless fabricated assemblies
For best results, position the narrow working edge directly 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
Especially suited for:
- Stainless steel
- Stainless steel weldments
- Stainless fabricated components
- Other compatible metals where stainless wire brushing is appropriate
Keep this brush dedicated to stainless steel work when preventing cross-contamination is important. A stainless wire brush previously used on carbon steel can pick up iron contamination and transfer it back to a stainless workpiece.
Store stainless and carbon steel brushes separately for contamination-sensitive applications.
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 each 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.
- Keep stainless brushes dedicated to stainless work when cross-contamination matters.
- Follow all operating and safety instructions for both the power tool and wire wheel.
