3M 7100178232 Flap Wheel 1.5 in Ao 120 Grit

Product Description

The 3M 7100178232 is a 244D series flap wheel designed for general-purpose grinding, polishing, sanding, and finishing on metal and similar surfaces. Built with aluminum oxide mineral, this wheel cuts sharply and holds up through extended use. The flap construction uses individually mounted abrasive flaps that continually lap the surface, helping to produce fine, consistent finishes. At 1.5 inches in diameter and 120 grit, it is well suited for detail work, surface preparation, and edge blending. A licensed trade technician, fabricator, or maintenance professional would typically install and operate this wheel on a compatible rotary tool or spindle.

This flap wheel is used in light fabrication, metalworking, and maintenance applications where controlled material removal and surface finishing are required. The 120 grit rating makes it appropriate for finishing passes and fine surface conditioning rather than heavy stock removal. It is sold in a minimum quantity of 10 units per order, making it practical for shop stocking. The wheel is compatible with Type 83 (T83) and Type 84 (T84) mounting systems, which should be confirmed against the host tool before use.

Installation Notes

This wheel should be installed and operated by personnel familiar with abrasive wheel safety practices. Always power down and disconnect the tool before mounting or removing the wheel.
