3 in Twist Knot Wire Wheel Brush
The Weiler 08004 is a 3 inch diameter wire wheel brush built with standard twist knot carbon steel bristles. It mounts on a 1/2 in to 3/8 in threaded arbor for use with die grinders, drill presses, pencil grinders and straight grinders. The brush targets metalworkers who need aggressive surface preparation on carbon steel.
Replaces worn or softer brushes for heavy cleaning
When an existing wheel no longer removes scale, rust or weld spatter efficiently, the 0.012 in diameter twist knot construction restores cutting speed. The upgrade is worth it when the job demands a narrow 3/8 in face width and a 5/8 in bristle length to reach confined areas on carbon steel workpieces.
Sustained high-speed operation up to 20000 RPM
The twist knot design resists premature wire breakage during continuous use at the rated maximum speed. Carbon steel bristles maintain stiffness under load, delivering consistent material removal without the rapid dulling seen in lighter crimped wire wheels during extended grinding sessions.

Questions about this item
What arbor size does the 3 in twist knot wire wheel brush need to fit my grinder?
The brush uses a threaded hole connector sized 1/2 in to 3/8 in for direct mounting on compatible die grinders, drill presses, pencil grinders or straight grinders.
How do I install the wire wheel brush and what step is often missed?
Thread the brush onto the tool's spindle by hand until snug, then tighten with the supplied wrench flats; the step often missed is verifying the tool's maximum RPM does not exceed 20,000 RPM before starting.
When will the carbon steel bristles on this 0.012 in diameter brush need replacement?
Replace the brush once the twist knot bristles wear down from their original 5/8 in length or show uneven wear that causes vibration during use.
