3M 7100138311 Mounted Flap Wheel 60 Grit Ceramic Alumina

Product Description

The 3M 7100138311 is a mounted flap wheel designed for blending, deburring, and finishing on metal and other hard surfaces. It uses a ceramic alumina abrasive on a cloth backing, which delivers consistent cut and long service life compared to conventional aluminum oxide media. The 1 inch diameter and 1 inch face width make this a compact tool suited for working in contoured areas and tight spaces. A 1/4 inch shank mounts directly into a die grinder or drill press. Rated to a maximum of 30,000 RPM, it falls in the medium grade range at 60 grit, making it a strong choice for material removal and surface prep before finishing passes.

This mounted flap wheel is used in metalworking, fabrication, and maintenance applications where a portable rotary abrasive is needed. It performs well on weld blending, edge conditioning, and light stock removal on steel, stainless, and alloy surfaces. The compact 1 inch face width is well suited for pipe work, tubing interiors, dies, molds, and narrow channels where larger wheels cannot reach. It is commonly installed by machinists, pipefitters, welders, and maintenance technicians working with angle grinders or die grinders.

Installation Notes

Installation is performed by machinists, fabricators, or maintenance technicians using a die grinder or drill press. Confirm the tool spindle speed does not exceed the 30,000 RPM maximum rating before mounting the wheel. Power down and disconnect the tool from its air or electrical supply before changing abrasive accessories. Inspect the flap wheel for damage before each use and do not exceed the rated RPM under any operating condition.
