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.
Compact 1" diameter for localized cleaning and detail work
Flexible abrasive bristles conform to irregular and contoured surfaces
Aluminum oxide abrasive provides dependable cleaning and conditioning performance
R-Type quick change mounting allows fast disc changes
Available in three grit options for heavier cleaning through finer conditioning
Effective for rust, paint, oxidation, varnish, and surface-contaminant removal
Suitable for cleaning, light deburring, blending, finishing, and surface preparation
Applications
Use the 1" Bristle Brush Quick Change Disc for:
Rust and oxidation removal
Paint and coating removal
Varnish removal
Surface-contaminant cleanup
Light deburring
Localized surface blending
Detail cleaning
Metal cleaning and conditioning
Surface preparation before coating or finishing
For best results, use light, controlled pressure and allow the abrasive bristles to perform the cutting action.
Materials
Suitable applications include:
Steel
Cast iron
Wrought iron
Titanium
Nickel and appropriate nickel alloys
Aluminum
Copper
Zinc alloys
Magnesium
Always test on a small area when surface appearance or dimensional preservation is critical.
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.

Benchmark Abrasives bristle brushes use aluminum oxide abrasive.
The 1" bristle brush is available in 50 grit green, 80 grit yellow, and 120 grit white.
Choose 50 grit for heavier cleaning and coating removal, 80 grit for balanced cleaning and conditioning, and 120 grit for finer surface conditioning, particularly on softer nonferrous metals such as aluminum.
Yes. A compatible 1" R-Type quick change holder is required and sold separately.
The maximum speed is 25,000 RPM, with a recommended operating range of 15,000–25,000 RPM. Never exceed the lowest speed rating of any component in the complete tool-and-accessory assembly.
Yes, with a matching 1" R-Type holder on a 1/4" shank. The holder must be rated for at least 24,500 RPM and clamped with the shank insertion specified in the tool manual. The holder is sold separately.
Yes. Choose 120 grit white for lighter conditioning, use light pressure, and test a small area to check the finish.
This brush is intended primarily for cleaning, coating removal, light deburring, blending, and surface conditioning. Heavy weld removal and significant stock removal require an abrasive designed for grinding.
