3M 7100178226 Mounted Flap Wheel 120 Grit Aluminum Oxide

Product Description

The 3M 7100178226 is a mounted flap wheel designed for precision grinding, blending, and finishing on metal and other hard surfaces. It uses a coated aluminum oxide abrasive bonded to a cloth backing with an XE backing weight, delivering consistent cut and finish at a fine 120 grit rating. The wheel mounts via a 1/4 inch shank and is rated for a maximum of 25,000 RPM, making it compatible with standard die grinders and rotary tools. Fabricators, machinists, and maintenance technicians use this wheel for deburring, surface conditioning, and weld blending on workpieces where controlled material removal and a refined surface finish are required.

This mounted flap wheel is suited for use in industrial fabrication shops, maintenance facilities, and machine shops. At 2 inches in diameter with a 1 inch face width, it is well matched to contoured surfaces, inside radii, and tight geometries where larger grinding tools cannot reach. The fine 120 grit classification makes it appropriate for finishing passes and light stock removal rather than aggressive initial grinding.

Key Features

• 120 grit aluminum oxide abrasive for fine-grade surface finishing and deburring
• Coated abrasive construction on a cloth backing for flexible, consistent contact
• 1/4 inch shank mount for use with standard die grinders and rotary tools
• 25,000 RPM maximum speed rating for high-speed rotary tool compatibility
• 2 inch diameter with 1 inch face width suits contoured and hard-to-reach surfaces
• XE-weight cloth backing provides durability and conformability across surface profiles

Compatibility

Designed for use with die grinders and rotary tools accepting a 1/4 inch shank accessory, suitable for grinding and finishing applications on metal and similar hard materials.

Installation Notes

Installation and use should be performed by a qualified machinist, fabricator, or maintenance technician familiar with abrasive wheel safety. Before mounting, confirm the tool spindle speed does not exceed the 25,000 RPM maximum rating of this wheel. Inspect the wheel for damage before each use and discard if any delamination or abnormal wear is present. Always use appropriate eye protection and follow ANSI B11 and OSHA 29 CFR 1910.215 abrasive wheel safety guidelines during operation.
