Tru-maxx 88541 Knotted Wheel Brush 4 Inch Stainless Steel

Product Description

The TRU-MAXX 88541 is a knotted wire wheel brush designed for aggressive surface preparation, weld cleanup, rust removal, and scale cleaning on metal workpieces. The 4-inch outside diameter wheel mounts via a 5/8-11 arbor hole, making it compatible with standard angle grinders and bench grinders used across fabrication, plumbing, and industrial maintenance applications. Wire is stainless steel construction with a standard twist knot configuration and a filament wire diameter in the 0.0100 to 0.0199 inch range. The 7/8-inch trim length provides the stiffness needed for heavy-duty surface work. Rated to 20,000 RPM, this brush handles high-speed tool operation without compromise.

This wheel brush suits applications where carbon steel wire would introduce contamination risk, such as stainless steel pipe prep, food-grade equipment maintenance, or any substrate where rust transfer from carbon wire is unacceptable. Plumbers, pipefitters, metal fabricators, and maintenance mechanics commonly specify stainless wire brushes for these conditions. The 1/2-inch face width concentrates cleaning action on narrow beads and seams. The 4-inch diameter keeps the tool compact enough for close-quarters work on flanged joints and structural connections.

Installation Notes

Installation should be performed by a qualified tradesperson or experienced operator following the grinder manufacturer's spindle mounting procedure. Always confirm the tool's free-speed RPM rating does not exceed the 20,000 RPM rating of this brush before mounting. Wear ANSI-rated eye protection and a face shield during operation, and inspect the brush for broken or missing wire before each use. Never exceed the rated speed and never use a wheel brush with visible wire fatigue or deformation.
