3-1/2 in crimped wire cup brush
This Weiler 13181 cup brush fits right-angle grinders with a 5/8-11 threaded spindle. Carbon steel crimped wire bristles measure 0.014 in diameter and 7/8 in length. The brush runs at a maximum of 13,300 RPM for surface preparation tasks.
Upgrade from knotted wire or abrasive discs
Crimped wire removes light rust, paint and scale while leaving a smoother finish than knotted wire brushes. The jump is worth it when the workpiece requires less aggressive material removal and reduced risk of gouging softer metals.
Threaded 5/8-11 hole mounts directly on grinder
No adapter or quick-change hub is needed, freeing up spindle length and reducing vibration. The 3-1/2 in diameter suits medium-sized grinding tools. Not for bench grinders, drill presses or tools lacking a 5/8-11 output shaft.

Questions about this item
What thread size does the 13181 cup brush need on a right-angle grinder?
The brush uses a 5/8-11 threaded hole, so the grinder spindle must match that exact thread.
How do you install the brush on the grinder, and what step is often missed?
Thread the brush onto the 5/8-11 spindle by hand until snug, then tighten with the grinder's wrench; the step often missed is confirming the brush spins freely before powering on.
When should the crimped wire cup brush be replaced?
Replace the brush when the .014 carbon-steel wires become worn down, broken, or the cup shape deforms, reducing cleaning effectiveness.
