3" Bristle Brush – Shaft Mounted

3" BRISTLE BRUSH – SHAFT MOUNTED

Benchmark Abrasives 3" 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 larger 3" working diameter provides efficient coverage while the flexible bristles conform to irregular surfaces, edges, and contours.

The integrated 1/4" round shank mounts directly into a compatible collet or chuck, eliminating the need for a separate quick change holder. Available in 50, 80, and 120 grit, this shaft-mounted brush provides a progression from heavier cleaning to finer surface conditioning for rust, paint, oxidation, varnish, and general surface cleanup.

Product Specifications

Features

• Flexible abrasive bristles conform to irregular and contoured surfaces
• Aluminum oxide abrasive provides dependable cleaning and conditioning performance
• 3" diameter provides increased working-area coverage
• 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
• Suitable for cleaning, light deburring, blending, finishing, and surface preparation

Applications

Use the 3" 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. No separate quick change holder is required.

Compatibility requires the machine to:

• Accept a true 1/4" shank
• Permit a 3" accessory diameter
• Permit this type of shaft-mounted abrasive brush
• Operate within the brush's 25,000 RPM maximum
• Provide adequate accessory clearance and proper shank engagement

A 6 mm collet is not interchangeable with a 1/4" collet. A 1/4" shank measures 6.35 mm and requires the correctly sized collet or chuck.

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 adequate clearance for the 3" brush before operation.
• Insert and secure the shank according to the power-tool manufacturer's instructions.
• 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.
• 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.
