3M 7100159582 Finishing Flap Brush 8x1x3 in 7S Super Fine

Product Description

The 3M 7100159582 is a finishing flap brush designed for light-duty cleaning and finishing applications across a range of surfaces. Individual abrasive sheets are adhered at a 90-degree angle to the core, creating a flap configuration that delivers consistent surface contact during use. The brush uses a super fine grade silicon carbide mineral, which is well suited for fine finishing, light deburring, and surface preparation work. The hard 7S density rating provides long service life while limiting conformability, keeping the action controlled on flat or low-contour surfaces. At 0.63 pounds, the brush is lightweight and easy to handle during extended operations.

This flap brush is used in industrial, maintenance, and fabrication settings where a controlled, consistent finish is required without aggressive material removal. The super fine silicon carbide mineral makes it appropriate for final-stage finishing passes on metal, composite, or similar materials. It is typically used with bench-mounted or portable rotary equipment. Maintenance technicians, fabricators, and finishing specialists working in light manufacturing or equipment service environments are the primary installers and operators of this brush.

Installation Notes

Installation is typically performed by a maintenance technician or fabrication specialist. Before mounting, power down and lock out the rotary equipment per applicable safety procedures. Verify that the spindle speed rating of the machine does not exceed the rated speed of the brush before operation. Inspect the flap sheets for damage before each use and replace the brush if sheets are torn or the core is compromised.
