3M 7000120878 Flap Wheel 6x1 Inch Aluminum Oxide Very Fine

Product Description

The 3M 7000120878 is a nonwoven aluminum oxide unmounted flap wheel designed for surface finishing, blending, and deburring on metal, wood, and composite materials. Measuring 6 inches in outside diameter by 1 inch in width with a 2-inch center hole, this wheel mounts to compatible arbors and spindles for bench or pedestal grinder applications. It carries a Very Fine grade designation and is rated for a maximum of 3,400 RPM. The nonwoven construction allows the abrasive to conform to contours and irregular surfaces, making it well suited for finishing work where consistency and surface quality matter. Fabricators, metalworkers, and maintenance technicians are the primary users.

This flap wheel is used in light to medium surface preparation and finishing operations. Common applications include removing light oxidation, blending weld seams, cleaning machined parts, and producing a uniform finish on flat or contoured workpieces. The nonwoven abrasive material resists loading and maintains consistent cut throughout the wheel life, making it practical for production or maintenance shop environments. It is sold individually and is intended for use with standard arbor-mounted spindle equipment.

Key Features

• Nonwoven aluminum oxide abrasive construction conforms to irregular and contoured surfaces
• Very Fine grade suitable for surface blending, light stock removal, and finish work
• 3,400 RPM maximum speed rating for use on bench or pedestal grinders

Compatibility

Designed as an unmounted flap wheel for use with bench grinders, pedestal grinders, and spindle-mounted arbors that accept a 2-inch center hole wheel at the appropriate RPM rating.

Installation Notes

Installation should be performed by a qualified technician familiar with abrasive wheel mounting procedures. Ensure the grinder or spindle is fully powered down and locked out before mounting or removing the wheel. Verify that the machine spindle speed does not exceed the 3,400 RPM maximum rating stamped on or associated with this wheel. Inspect the wheel for damage before use and confirm the arbor flanges are clean and properly seated before operating.
