3M 7100171901 Mounted Flap Wheel 80 Grit 1-1/2 in Aluminum Oxide

Product Description

The 3M 7100171901 is a mounted flap wheel abrasive designed for precision grinding, blending, and finishing on metal and other hard surfaces. It features an aluminum oxide coated abrasive on a cloth backing rated XE weight, delivering consistent stock removal at a medium grade 80 grit. The 1/4-inch shank mounts directly into a die grinder or drill press, making it a practical tool for machinists, fabricators, and maintenance technicians working in tight or contoured areas. Maximum operating speed is 22,000 RPM. The cloth-backed flap construction allows the wheel to conform to curved and irregular surfaces while maintaining even abrasive contact throughout the cut.

This mounted flap wheel is suited for deburring, surface conditioning, and weld blending on ferrous and non-ferrous metals in both shop and field settings. Its compact 1-1/2-inch diameter and 1/2-inch face width make it effective in confined spaces where larger wheels cannot reach, such as inside tubing, bores, or tight weld joints. It is a common tool in metal fabrication shops, HVAC ductwork finishing, and general maintenance applications where a handheld rotary tool is used.

Key Features

• 80 grit medium grade aluminum oxide abrasive for consistent material removal and surface blending
• XE-weight cloth backing provides durability and flexibility on contoured surfaces
• 1/4-inch shank mounts to standard die grinders and rotary tools without adapters
• 22,000 RPM maximum operating speed rated for high-speed rotary tool use
• Compact 1-1/2-inch diameter and 1/2-inch face width for access in confined areas
• No interleaf construction delivers direct abrasive contact per pass

Compatibility

Designed for use with standard 1/4-inch collet die grinders and rotary tools rated to at least 22,000 RPM. Suitable for grinding and finishing applications on metal, welds, and similar hard materials.

Installation Notes

Always verify the tool spindle speed does not exceed the 22,000 RPM maximum rating before mounting this wheel. Disconnect power to the rotary tool before installing or removing the shank. Secure the 1/4-inch shank fully into the collet and tighten according to the tool manufacturer's torque guidelines. Wear appropriate eye protection and ensure workpiece is properly fixtured before operation.
