3M 7000046180 Radial Bristle Brush 6in X 7/16in 6 Micron

Product Description

The 3M 7000046180 is a radial bristle brush designed for surface preparation, cleaning, and finishing across metal and coated surfaces. It measures 6 inches in diameter with a 7/16-inch arbor hole and 1-inch trim width, and features a 6-micron abrasive rating using aluminum oxide and Cubitron abrasive grain. The bristle construction applies abrasive action with minimal pressure, reducing operator fatigue and limiting the risk of substrate damage common with conventional wire brushes. A universal bench motor adapter is included. Licensed tradespeople and maintenance technicians in HVAC, fabrication, and general mechanical service use this tool for deburring, rust removal, and surface conditioning.

This radial bristle brush suits applications requiring controlled, consistent surface prep without aggressive material removal. It performs on bare metal, coated steel, aluminum, and similar substrates. The low-pressure cutting action makes it appropriate for work on precision components or finished assemblies where wire brush scoring is unacceptable. Typical use cases include weld prep, oxide removal, and light cleaning on tubing, fittings, and sheet metal components common in HVAC and plumbing rough-in work.

Key Features

• 6-micron abrasive rating delivers fine, controlled surface action
• Aluminum oxide and Cubitron abrasive grain for consistent cut performance
• Radial bristle design applies abrasive with minimal applied pressure
• Safe alternative to wire brushes, reducing risk of wire fragment embedment
• Universal bench motor adapter included in package
• Works on a variety of coatings and base metal surfaces

Compatibility

Designed for use with bench motors and rotary tools accepting the included universal adapter. Suitable as a direct replacement for wire brushes in surface prep and cleaning applications on metal substrates.

Installation Notes

Installation and operation should be performed by qualified tradespeople familiar with rotary abrasive tooling. Ensure the bench motor or rotary tool is fully powered down and unplugged before mounting or removing the brush. Verify that the tool RPM rating does not exceed the maximum rated speed of the brush before operation. Always wear appropriate eye protection and follow applicable OSHA standards when using abrasive accessories.
