3M 7100178247 Mounted Flap Wheel 60 Grit 1 in Aluminum Oxide

Product Description

The 3M 7100178247 is a mounted flap wheel abrasive designed for deburring, blending, and finishing work on metal, wood, and composite surfaces. It uses aluminum oxide abrasive bonded to a cloth backing with an XE backing weight, delivering consistent cutting action across the full face of the wheel. Rated to 30,000 RPM maximum, this wheel mounts directly to a rotary tool or die grinder via a 1/4-inch shank. At 60 grit, it falls in the medium grade range, making it a practical choice for stock removal and surface preparation before finer finishing steps. Metalworkers, machinists, and fabricators commonly reach for this style of tool when working in bores, contours, or tight geometry that flat abrasives cannot reach.

This mounted flap wheel suits applications in metal fabrication shops, maintenance and repair operations, and production grinding environments. Its 1-inch diameter and 1-inch face width make it well-suited for internal diameter work, weld blending in confined areas, and edge conditioning on machined parts. It is sized for use with standard die grinders and flexible-shaft tools equipped with a 1/4-inch collet.

Key Features

• Aluminum oxide coated abrasive on cloth backing for durable, consistent cut
• 60 grit medium grade for stock removal and surface blending
• 30,000 RPM maximum speed rating for use with high-speed rotary tools
• 1/4-inch shank mount for direct chuck or collet installation
• 1-inch diameter by 1-inch face width for access in tight or contoured areas
• No interleaf design for direct abrasive-to-workpiece contact

Compatibility

Designed for use with die grinders, rotary tools, and flexible-shaft machines equipped with a 1/4-inch collet or chuck capable of operating at or below 30,000 RPM.

Installation Notes

Installation should be performed by a qualified operator familiar with rotary abrasive tooling and applicable shop safety standards. Always power down and disconnect the tool before mounting or removing the wheel. Confirm the tool spindle speed does not exceed the 30,000 RPM maximum rating marked for this wheel before operating. Inspect the wheel for damage before each use and do not use if the abrasive or shank shows visible wear, bending, or defects.
