3M 7000120563 Aluminum Oxide Flap Wheel 8x1 Inch Very Fine

Product Description

The 3M 7000120563 is a nonwoven aluminum oxide unmounted flap wheel designed for surface finishing, blending, and light deburring on metal and similar substrates. Measuring 8 inches in outside diameter and 1 inch in width with a 3-inch center hole, this wheel mounts on arbor-style grinders and finishing machines. Rated to a maximum of 3,200 RPM, it carries a Very Fine grade designation with a flap density of 5, making it well suited for final-pass finishing work where a consistent scratch pattern and surface uniformity are required. It ships as a single unit and is used by metalworkers, fabricators, and industrial maintenance technicians.

This flap wheel is applied in metal fabrication shops, welding operations, and general industrial maintenance settings where controlled surface finishing is needed. The nonwoven construction allows the wheel to conform slightly to irregular surfaces, making it useful on curved or contoured workpieces. Very Fine grade aluminum oxide is appropriate for finishing passes following coarser stock removal, or for cleaning and light blending on stainless steel, mild steel, and similar materials. It is installed on bench-mounted or stand-mounted arbor grinders and comparable finishing equipment.

Key Features

• Nonwoven aluminum oxide construction for consistent, controlled surface finishing
• Very Fine grade suitable for final finishing, blending, and light deburring
• 8-inch outside diameter with 3-inch center hole for arbor-mount compatibility
• Maximum rated speed of 3,200 RPM
• Flap density of 5 for even abrasive contact across the work surface
• No interleaf design for straightforward flap-wheel performance

Compatibility

Designed for use on arbor-style grinders and finishing machines that accept an unmounted flap wheel with a 3-inch center hole and up to 8-inch outside diameter. Verify that the host machine is rated for the 8-inch wheel diameter and does not exceed 3,200 RPM before mounting.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety and machine guarding requirements per applicable ANSI B11 or OSHA standards. Always power down and lock out the machine before mounting or removing the wheel. Confirm that the spindle speed does not exceed the 3,200 RPM maximum rating marked on this wheel. Inspect the wheel for damage before each use and never operate a cracked or deformed abrasive wheel.
