Product Specification
7" STRINGER BEAD WIRE WHEEL - CARBON STEEL
For large weldments, structural fabrication, and heavy maintenance work where you still need a narrow, aggressive cleaning edge, the 7" Stringer Bead Wire Wheel - Carbon Steel brings extra reach without giving up the focused action that makes a stringer wheel valuable. Built with 0.020" carbon steel wire, it is designed to attack weld scale, slag residue, oxidation, rust, spatter, and stubborn buildup inside weld passes, grooves, seams, and other tight areas.
The tightly twisted stringer-bead construction keeps the wire stiff and concentrated instead of spreading the cleaning action across a broad face. That focused profile makes it especially effective for interpass cleaning, root-pass work, groove cleaning, and other welding applications where access and control matter just as much as aggressive removal.
Its larger 7" diameter provides greater reach on bigger fabricated assemblies while maintaining the narrow working edge needed for concentrated weld cleaning. 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 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 seam cleaning
- Surface preparation before welding
- Structural-steel fabrication
- Pipeline and heavy maintenance work
- Cleaning large fabricated assemblies
The larger 7" diameter provides added reach for substantial workpieces while preserving the concentrated stringer-bead working edge. Use controlled pressure and allow the wire tips to perform the cleaning 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 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.
- Follow all operating and safety instructions for both the power tool and wire wheel.
