Benchmark Abrasives 2" shaft mounted bristle brushes use aluminum oxide abrasive throughout flexible bristles for controlled cleaning, coating removal, light deburring, blending, and surface conditioning on metal. The compact 2" diameter works well in tighter areas and on smaller surfaces where a larger brush may be less maneuverable.
The integrated 1/4" round shank mounts directly into a compatible 1/4" collet or chuck, eliminating the need for a separate quick change holder. Available in 50, 80, and 120 grit, this shaft-mounted design gives you a progression from heavier cleaning to finer conditioning for rust, paint, oxidation, varnish, and general surface cleanup.
None – mounts directly in a compatible 1/4" collet or chuck
Features
Flexible abrasive bristles conform to irregular and contoured surfaces
Aluminum oxide abrasive provides dependable cleaning and conditioning performance
2" diameter offers good control in smaller or more confined areas
Integrated 1/4" round shank mounts directly into a compatible tool
No separate quick change backing pad or holder required
Available in three grit options for heavier cleaning through finer conditioning
Effective for rust, paint, oxidation, varnish, and surface-contaminant removal
Applications
Use the 2" Shaft Mounted Bristle Brush for:
Rust and oxidation removal
Paint and coating removal
Varnish removal
Surface-contaminant cleanup
Light deburring
Surface blending
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 brush mounts directly into a compatible 1/4" collet or chuck. A 6 mm collet is not the same as a 1/4" collet and should not be treated as interchangeable.
Compatible examples include:
Milwaukee® 2485-20 M12 FUEL™ Right Angle Die Grinder — use with the 1/4" collet and verify proper shank insertion before use.
Do not assume compatibility based on collet size alone. Confirm that the machine permits the accessory diameter and type and that the tool speed does not exceed the brush's 25,000 RPM maximum.
Safety Tips
Do not exceed the 25,000 RPM maximum speed of the brush.
Use only with a properly sized 1/4" collet or chuck.
Do not substitute a 6 mm collet for a 1/4" shank.
Verify proper shank insertion and secure clamping before operation.
Inspect the brush and shank before each use.
Do not use damaged, cracked, excessively worn, bent, or improperly mounted components.
Use light, controlled pressure rather than forcing the brush into the workpiece.

Frequently Asked Questions
It is designed for metal cleaning and surface conditioning applications including rust, paint, oxidation, varnish, and surface-contaminant removal, along with light deburring and blending.
Benchmark Abrasives bristle brushes use aluminum oxide abrasive.
It uses a 1/4" round shank.
No. The shaft-mounted design installs directly into a compatible 1/4" collet or chuck.
No. A 1/4" shank measures 6.35 mm, so a 6 mm collet is a different size and should not be treated as interchangeable.
The 2" shaft mounted 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.
The maximum speed is 25,000 RPM, with a recommended operating range of 15,000–25,000 RPM. The tool and accessory setup must remain within all applicable speed limits.
Yes. Use its 1/4" collet and follow the manual's shank insertion and clamping instructions. This 2" brush is within the tool's 2" accessory limit, and its 25,000 RPM rating exceeds the tool's 24,500 RPM maximum.
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.
