3M 7100173784 Flap Wheel 3 in 120 Grit Aluminum Oxide

Product Description

The 3M 7100173784 is a 244D series aluminum oxide flap wheel designed for general-purpose grinding, polishing, sanding, and finishing on metal and other hard surfaces. At 3 inches in diameter and 120 grit, it delivers a controlled cut with a fine surface finish. The flap construction uses individually mounted abrasive flaps that continuously lap the workpiece, exposing fresh mineral as the wheel wears. The aluminum oxide abrasive cuts sharp and holds up through extended use. Licensed HVAC technicians, machinists, welders, and fabricators reach for this wheel when surface prep and finish quality both matter.

This flap wheel suits a wide range of trade applications including weld blending, deburring, edge finishing, and surface conditioning on ferrous and non-ferrous metals. It fits standard Type 83 and Type 84 mandrel mounting systems, making it compatible with common die grinders and rotary tools used in mechanical, HVAC, plumbing, and electrical rough-in work where tube ends, pipe fittings, and sheet metal edges require cleanup before assembly.

Key Features

• Aluminum oxide mineral delivers a sharp, long-lasting cut with fine finish capability
• Individually mounted abrasive flaps continually lap the surface for consistent stock removal
• X-weight cotton cloth backing resists tearing and flexes to follow contours without gouging
• Compatible with Type 83 and Type 84 mandrel mounting systems
• 3 inch diameter at 120 grit suits finish grinding and light material removal
• Coated abrasive construction stands up to edges and irregular surfaces

Compatibility

Designed for use with Type 83 and Type 84 mandrel mounting systems on standard die grinders and rotary tools accepting 3 inch diameter flap wheels.

Installation Notes

Install and remove abrasive wheels only with the tool fully de-energized and the power source disconnected or locked out per applicable OSHA lockout-tagout procedures. Inspect the wheel for damage before each use and do not exceed the rated RPM of the wheel or tool. Wear appropriate eye and face protection, as well as gloves, when operating grinding or finishing equipment.
