3M 7100178228 Mounted Flap Wheel 80 Grit 2 in Aluminum Oxide

Product Description

The 3M 7100178228 is a mounted flap wheel abrasive designed for grinding, blending, and finishing on metal, wood, and composite surfaces. Built with aluminum oxide abrasive on a cloth backing rated XE weight, it delivers consistent cut and finish across irregular contours and curved surfaces. The wheel mounts directly to a rotary tool or die grinder via a 1/4 inch shank. At 80 grit medium grade, it sits at the intersection of aggressive material removal and surface conditioning, making it a go-to choice for weld blending, deburring, and edge cleanup in fabrication and maintenance work.

This mounted flap wheel is suited for use in metal fabrication shops, HVAC ductwork finishing, mechanical maintenance, and general trade applications where a die grinder or rotary tool is the primary tool. The 2 inch diameter and 1 inch face width cover a practical working surface for both flat and contoured workpieces. It operates without an interleaf between flaps, which keeps the cut aggressive and consistent throughout the wheel life. Professionals in welding, pipefitting, and equipment maintenance commonly reach for this size and grit combination for routine material prep tasks.

Installation Notes

A licensed tradesperson or experienced operator should confirm the tool spindle speed does not exceed the 25,000 RPM maximum rating before mounting this wheel. Secure the shank firmly in the collet and inspect the wheel for damage before each use. Always wear appropriate eye and face protection when operating rotary abrasive tools. Power down and disconnect the tool from its power source before changing or adjusting the mounted wheel.
