Wire wheel brush for die grinders and drills
This crimped wire wheel brush fits die grinders, pencil grinders, straight grinders and drill presses. It has a 3 inch diameter, a 3/8 inch face width and a threaded hole that accepts 1/2 in to 3/8 in adapters. The nylon bristles are 0.04 inch in diameter and 1/2 inch long with a 120 grit rating. Maximum operating speed is 20,000 RPM.
Surface preparation on carbon steel
The brush is intended for cleaning, deburring and light finishing on carbon steel components. It is not suitable for heavy stock removal, aggressive rust stripping or work on hardened alloys that require a coarser or more durable abrasive. Users needing wider coverage or higher material removal rates should consider a larger diameter or broader face wheel.
20,000 RPM maximum speed rating
The 20,000 RPM limit is the critical specification that determines whether the brush matches the tool. Running the wheel above this speed can cause bristle failure and safety hazards. Verify that the grinder or drill press does not exceed 20,000 RPM before mounting the brush.

Questions about this item
How long can I run the Weiler 31094 at 20000 RPM before the wire bristles wear down?
The 0.04 in diameter crimped nylon bristles with 120 grit will gradually reduce in length from their 1/2 in starting point during sustained high-speed use on carbon steel.
Does the brush generate excessive heat or vibration during extended die grinder sessions?
Nylon bristles run cooler than wire and the 3/8 in face width limits contact area, reducing heat buildup and vibration on die grinders or pencil grinders.
Which arbor adaptor do I need to mount this on my 1/2 in spindle grinder?
The threaded hole accepts 1/2 in to 3/8 in reducers, so you must already own the correct reducer for your specific spindle size.
