Brass Crimped Wire Wheel Brush

The Weiler 29178 is a 1-1/2 inch diameter brass wire wheel brush designed for use with die grinders. It targets metalworkers and maintenance technicians who need a non-ferrous brushing tool for light surface preparation on carbon steel.

20000 RPM Maximum Operating Speed

The brush carries a maximum safe operating speed of 20,000 RPM, which sets a hard limit for the die grinder used to drive it. Exceeding this speed risks wire separation and safety hazards, so the power tool must be rated at or below this figure.

3/8 Inch Threaded Hole Mounting

A 3/8 inch threaded hole provides the arbor connection, meaning the brush fits directly onto compatible die grinder spindles without extra adapters. The 0.005 inch diameter crimped brass wires and 1/4 inch face width produce a flexible brushing action suited to contour following rather than aggressive material removal.

Questions about this item

Which brush diameter should I pick for my die grinder?

The 1-1/2 inch diameter matches the spec for this crimped wire wheel and fits the 3/8 inch threaded arbor on compatible die grinders.

What does the 20,000 RPM rating mean when the wheel is spinning on the tool?

It is the maximum safe operating speed; running the brass crimped wheel faster risks wire breakage and reduces brush life.

How does the 3/8 inch threaded hole limit which tools I can use?

Only die grinders or shafts with a matching 3/8 inch threaded arbor can mount this wheel; other arbor sizes will not fit.
