3M 7000120990 Flap Brush 8x2x3 Inches Medium Polish

Product Description

The 3M 7000120990 is a cut and polish flap brush designed for surface finishing applications that require a higher degree of polish. Individual abrasive sheets are adhered at a 90-degree angle to the core, creating a flap-style construction that conforms to contours while maintaining consistent cutting action. The abrasive mineral is medium-grade aluminum oxide, and the brush is rated at a medium hardness density of 5A. At 1.75 pounds, it is a heavy-duty tool built for demanding finishing work on metal, composites, and similar industrial surfaces.

This flap brush is suited for metal fabrication shops, maintenance facilities, and industrial production environments where operators need to cut and polish in a single step. The 8 inches x 2 inches x 3 inches form factor fits standard arbor-mounted setups commonly used by machinists, metalworkers, and maintenance technicians. It is appropriate for applications where consistent surface finish quality is critical and coarser abrasive methods would leave unacceptable scratch patterns.

Key Features

• Medium-grade aluminum oxide abrasive mineral for balanced cutting and polishing action
• Individual sheets adhered at 90 degrees to the core for conforming, consistent contact
• Medium hardness 5A density rating for heavy-duty finishing applications
• 8 inches x 2 inches x 3 inches dimensions fit standard arbor-mounted equipment
• Heavy-duty construction suitable for applications requiring higher polished finishes

Compatibility

Designed for use with arbor-mounted rotary finishing equipment in industrial and fabrication settings where medium-grade cut and polish performance is required.

Installation Notes

Mount the flap brush on a compatible arbor-driven spindle following the equipment manufacturer's specified speed ratings. Ensure the machine is fully powered down and locked out before installing or removing the brush. Operators should wear appropriate PPE including eye protection and gloves during installation and use. Follow applicable ANSI and OSHA abrasive product safety guidelines for rotating equipment.
