Product Specification
7" STRINGER BEAD WIRE WHEEL - STAINLESS STEEL
For large stainless weldments, structural fabrication, and heavy maintenance work where you still need a narrow, aggressive cleaning edge, the 7" Stringer Bead Wire Wheel - Stainless Steel combines added reach with concentrated brushing action. Built with 0.020" stainless steel wire, it is designed to attack weld scale, oxidation, residue, rust, and stubborn buildup inside weld passes, grooves, seams, and other tight areas while helping minimize iron cross-contamination on stainless work.
The tightly twisted stringer-bead construction keeps the wire stiff and focused instead of spreading the cleaning action across a broad surface. That concentrated profile makes this wheel especially useful for weld-pass cleaning, groove access, and other fabrication work where precise contact with the weld area matters.
Its larger 7" diameter provides greater reach on substantial fabricated assemblies while maintaining the narrow working profile that defines a stringer bead wheel. A 5/8"-11 threaded arbor provides quick spin-on installation on compatible large-frame angle grinders, and the wheel carries a 9,000 RPM maximum rating.

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 confined areas where a wider brush may be less effective.
Common applications include:
- Cleaning between weld passes
- Stainless weld bead cleanup
- Removing weld scale and residue
- Oxidation and surface buildup removal
- Cleaning narrow grooves and joints
- Rust and corrosion removal
- Edge and seam cleaning
- Surface preparation before welding
- Structural and fabrication maintenance
- Cleaning large stainless fabricated assemblies
The larger 7" diameter gives the operator additional reach while preserving the concentrated stringer-bead working edge. Use controlled pressure and let the wire tips perform the cleaning rather than forcing the wheel deeper into the joint.
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.
Machine Compatibility
Use this 7" wire wheel on a compatible angle grinder with a 5/8"-11 spindle, adequate brush capacity and a maximum speed no greater than 9,000 RPM. Match the actual hub seating and allow room for wire flare.
Compatible examples include:
-
DEWALT® D28499 — 7" / 9" angle grinder; 6,000 RPM; use its 7" Type 27 guard.
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 9,000 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 7" 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.
- 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.
