3M 7100178213 Mounted Flap Wheel 80 Grit Aluminum Oxide

Product Description

The 3M 7100178213 is a mounted flap wheel abrasive designed for blending, finishing, and deburring on metal and similar surfaces. Built with aluminum oxide abrasive on a cloth backing, it delivers consistent medium-grade cutting action at 80 grit. The 1/4-inch shank mounts directly into a die grinder or drill press, making it a straightforward tool for tight spots and contoured work. Rated to 22,000 RPM, it handles high-speed material removal without degrading prematurely. The XE-weight cloth backing provides added durability under sustained use. Machinists, fabricators, and metal finishing technicians are the typical users.

This mounted flap wheel suits applications in metal fabrication shops, maintenance and repair operations, and production grinding environments. It is well suited for edge blending, weld seam cleanup, and surface preparation on inside diameters, slots, and recesses where larger wheels cannot reach. The 1-1/2-inch diameter and 1-inch face width give it a useful working surface for controlled finishing passes on both flat and curved surfaces.

Key Features

• Aluminum oxide coated abrasive for reliable medium-grade cutting on metal
• 80 grit provides a balance of material removal and surface finish quality
• 22,000 RPM maximum rating suits standard die grinders and high-speed rotary tools
• 1/4-inch shank for direct mounting in die grinders or drill chucks without adapters
• XE-weight cloth backing resists tearing under sustained grinding pressure
• Non-interleaved flap construction for consistent, even abrasive contact

Compatibility

Designed for use with die grinders, flexible shaft machines, and drill presses equipped with a 1/4-inch collet or chuck. Confirm tool RPM rating meets or exceeds the wheel maximum before use.

Installation Notes

Installation is performed by trade professionals including machinists, fabricators, and maintenance technicians. Power down and disconnect the tool from its power source before mounting or removing the wheel. Insert the 1/4-inch shank fully into the collet or chuck and tighten securely before operation. Always verify the tool RPM does not exceed the 22,000 RPM maximum rating of the wheel.
