1" BRISTLE BRUSH – QUICK CHANGE DISC
Benchmark Abrasives 1" bristle brush quick change discs use aluminum oxide abrasive throughout flexible bristles for controlled cleaning, coating removal, light deburring, blending, and surface conditioning on metal. The compact 1" diameter is ideal for localized work, tight areas, smaller surfaces, and detail cleaning where larger abrasive brushes may be harder to control.
The R-Type quick change connection allows fast disc changes while maintaining a secure attachment to a matching 1" holder. Available in 50, 80, and 120 grit, this brush provides a progression from heavier cleaning to finer surface conditioning for rust, paint, oxidation, varnish, and general surface cleanup.

Machine Compatibility
This disc requires a matching 1" R-Type quick change holder. The holder, disc, and machine must all be properly rated for the tool's maximum speed.
Compatible examples include:
- Milwaukee® 2485-20 M12 FUEL™ Right Angle Die Grinder — use with a matching 1" R-Type holder with a 1/4" shank rated for at least 24,500 RPM.
Do not assume compatibility based solely on collet size or holder connection. Confirm that the machine permits the accessory diameter and type and that every component in the assembly is properly speed rated.
Safety Tips
- Do not exceed the 25,000 RPM maximum speed of the brush.
- Always follow the lowest RPM rating of the brush, holder, and power tool.
- Use only a properly sized and securely mounted 1" R-Type quick change holder.
- Verify the holder's shank size, speed rating, and secure seating before operation.
- Inspect the brush and holder before each use.
- Do not use damaged, cracked, excessively worn, or improperly seated components.
- Use light, controlled pressure rather than forcing the brush into the workpiece.
-
Wear appropriate PPE, including safety glasses with side shields, a face shield when needed, hearing protection, gloves, and suitable respiratory protection when required.
- Secure the workpiece before beginning operation.
