2" Dia 1" Face Width 120 Grit Aluminum Oxide Mounted Flap Wheel, 7100178226

3M Flap Wheel 244D is a general-purpose flap wheel designed for grinding, polishing, sanding and finishing. Versatile aluminum oxide mineral cuts sharp, while the flap construction helps deliver fine finishes with individually-mounted abrasive flaps that continually lap the surface.
Type 83 vs. Type 84 Attachments 3M Flap Wheel 244D is offered in type 83 (T83) or type 84 (T84). The flap wheel is offered in both attachment styles, so operators can select the right wheel that aligns with their power tools. T83 has a 1/4" straight shaft that connects to a tool, such as a die grinder , and is locked in place with a collet. The longer shaft length of T83 may be desirable when operators need a bit of an extended reach between abrasive and workpiece. Conversely, T84 is a 1/4 - 20 threaded spindle mount, so it threads directly onto the tool. Its reach is shorter, which may be desirable when operators desire closer contact with the workpiece. Overall, this wheel may be attached to bench motors, die grinders and inline sanders.
