3M 7100178244 Flap Wheel 1 in 80 Grit Aluminum Oxide 1/4-20

Product Description

The 3M 7100178244 is a 244D series general-purpose flap wheel engineered for grinding, polishing, sanding, and finishing on a variety of surfaces. At 1 inch in diameter with an 80-grit aluminum oxide abrasive and a 1/4-20 arbor mount, this coated wheel is built for use with standard rotary tools and die grinders. The aluminum oxide mineral cuts sharp and holds up through extended use. Individually-mounted abrasive flaps continually lap the workpiece surface, allowing controlled material removal while producing fine, consistent finishes. An X-weight cotton cloth backing adds durability and flexibility, reducing the risk of gouging or marring the substrate.

This flap wheel is suited for metal finishing, surface prep, and deburring applications in fabrication shops, maintenance facilities, and light industrial environments. It fits standard rotary and die grinder setups via the 1/4-20 arbor. The 244D is compatible with both Type 83 (T83) and Type 84 (T84) mounting systems, giving it flexibility across a range of tool configurations. Typical users include machinists, pipefitters, fabricators, and maintenance technicians working on ferrous and non-ferrous metals.
