3M 7100062947 Aluminum Oxide Flap Wheel 8x2 in Fine

Product Description

The 3M 7100062947 is a nonwoven aluminum oxide unmounted flap wheel designed for surface finishing, blending, and light deburring on metal, wood, and composite materials. Measuring 8 inches in outside diameter and 2 inches in width with a 3-inch center hole for arbor mounting, this flap wheel runs at a maximum of 3,200 RPM. The fine-grade nonwoven construction delivers consistent scratch patterns and controlled material removal, making it a reliable choice for finishing passes where surface quality matters. Fabricators, metalworkers, and maintenance technicians install this wheel on bench grinders, floor-standing pedestal grinders, or compatible spindle-mounted setups.

This flap wheel suits applications in metal fabrication shops, manufacturing facilities, and maintenance environments where a fine surface finish is required on ferrous and non-ferrous metals. Typical uses include weld blending, edge finishing, and surface preparation before coating or inspection. The nonwoven construction conforms slightly to contours, making it useful for parts with irregular profiles. It is sold individually and is intended for professional shop use where consistent, repeatable finish quality is needed across production runs or repair work.

Key Features

• Nonwoven aluminum oxide abrasive delivers a fine, consistent surface finish
• 8-inch outside diameter and 2-inch width for broad contact area on flat and curved surfaces
• 3-inch center hole fits standard arbor-mounted bench and pedestal grinders
• 3,200 maximum RPM rating for use on appropriate fixed-spindle equipment
• Fine grade suits weld blending, pre-coat surface prep, and light deburring
• Unmounted design allows direct arbor installation without additional backing hardware

Compatibility

Designed for use on bench grinders, pedestal grinders, and spindle-mounted finishing equipment that accept a 3-inch arbor bore and operate at or below 3,200 RPM.

Installation Notes

Installation should be performed by a qualified fabricator or shop technician familiar with abrasive wheel mounting procedures. Power down and lock out the grinder before mounting or removing the flap wheel. Verify that the machine spindle speed does not exceed the 3,200 RPM maximum rating marked on the wheel before operation. Inspect the wheel for damage before each use and never exceed the rated maximum RPM.
