3M 7100178214 Flap Wheel 2 in 80 Grit Aluminum Oxide

Product Description

The 3M 7100178214 is a 244D series general-purpose flap wheel designed for grinding, polishing, sanding, and finishing applications across metal fabrication and surface preparation work. Built with aluminum oxide mineral abrasive, it cuts aggressively while still producing fine surface finishes. The individually mounted abrasive flaps continually lap the work surface as the wheel wears, exposing fresh cutting mineral throughout the wheel's life. An X-weight cotton cloth backing provides durability and enough flex to reduce gouging and marring on contoured or irregular surfaces. This wheel mounts via a 1/4-20 arbor and measures 2 inches in diameter.

This flap wheel suits a wide range of trades including metal fabricators, welders, pipefitters, and maintenance technicians working on deburring, blending welds, and finishing metal surfaces. At 80 grit, it sits in the medium-abrasive range, making it effective for material removal tasks that still require a reasonably smooth final surface. The wheel is offered in Type 83 (T83) and Type 84 (T84) mounting configurations, giving installers flexibility across compatible rotary tool platforms used in both shop and field environments.

Compatibility

Designed for use with rotary tools and die grinders accepting a 1/4-20 arbor, and compatible with Type 83 (T83) and Type 84 (T84) mounting systems.

Installation Notes

This wheel is installed by trades professionals using die grinders or similar rotary power tools — always confirm the tool's RPM rating meets or exceeds the wheel's maximum rated speed before mounting. Disconnect the tool from power before changing wheels. Inspect the flap wheel for damage before each use and discard any wheel showing torn flaps, cracks, or hub damage. Follow applicable ANSI B11 and OSHA abrasive wheel safety guidelines during installation and operation.
