3M Radial Bristle Brush 6 in 400 Grit
This 3M radial bristle brush uses ceramic bristles in a blue Type C configuration for finishing tasks. It mounts on a bench or pedestal grinder with a 1 in unthreaded hole and runs up to 6,000 RPM. The 6 in diameter and 7/16 in face width suit metal surface preparation.
Replaces wire wheels and coated abrasive discs
The bristle design reduces loading and maintains a consistent cut on aluminum, brass, bronze, cast iron, stainless steel and steel. Switching is worthwhile when you need a finer 400 grit finish without changing wheels for different metals.
Suits metalworkers finishing mixed alloys
Buyers who need aggressive stock removal or a coarser grit should look at other options. The fixed 400 grit and 6 in diameter limit flexibility for heavy deburring or large-area polishing.

Questions about this item
What size unthreaded hole does the 3M 61500187762 brush need to mount on a bench or pedestal grinder?
The brush has a 1 in unthreaded hole that fits directly onto the arbor of a compatible bench grinder or pedestal grinder running up to 6,000 RPM.
How do I install the radial bristle brush on my grinder, and what step is often missed?
Slide the brush onto the arbor, add any required washers or flanges, then tighten the grinder's locking nut securely; the step often missed is verifying the grinder speed does not exceed 6,000 RPM before starting.
When will the blue 400 grit ceramic bristles need replacement?
Replace the brush when the bristles wear down enough that they no longer contact the workpiece evenly or when the cutting action on aluminum, brass, bronze, cast iron, stainless steel or steel becomes noticeably slower.
