Tru-maxx 88548 7 Inch Stringer Bead Wheel Brush

Product Description

The TRU-MAXX 88548 is a stringer bead twist wire wheel brush designed for aggressive surface preparation and weld cleaning on metal workpieces. It mounts via a threaded 5/8-11 arbor hole, making it compatible with standard angle grinders and bench grinders used in fabrication, welding, and maintenance applications. The brush uses carbon steel fill material with a filament wire diameter in the 0.020 to 0.029 inch range, providing firm, consistent contact for removing slag, scale, rust, and weld spatter. At 7 inches in outside diameter with a 1-1/8 inch trim length and 3/16 inch face width, it is built for detail work along weld beads and seams.

This wheel brush is well suited for professional welders, pipefitters, ironworkers, and metal fabricators working in both shop and field environments. The stringer bead wire configuration concentrates wire tips into tight knots, which focus cleaning action along narrow weld passes and in tight joint profiles. It is appropriate for use on carbon steel, structural steel, and similar ferrous surfaces where aggressive mechanical cleaning is required before inspection, coating, or further weld passes.

Installation Notes

Installation is performed by welders, fabricators, or maintenance technicians using standard threaded arbor grinders. Before mounting, confirm the grinder spindle thread matches the 5/8-11 arbor hole specification and verify the tool RPM rating does not exceed the brush maximum RPM. Always power down and unplug or lock out the grinder before mounting or removing the brush. Wear appropriate PPE including a face shield rated for grinding operations, as wire bristles can shed at speed.
