3M 7100178227 Mounted Flap Wheel 60 Grit Aluminum Oxide

Product Description

The 3M 7100178227 is a mounted flap wheel designed for deburring, blending, and surface finishing on metal and similar materials. It uses aluminum oxide abrasive on a cloth backing with an XE backing weight, delivering medium-grade cut at 60 grit. The wheel measures 3 inches in diameter with a 1 inch face width and mounts via a 1/4 inch shank, making it compatible with standard die grinders and rotary tools. It is rated to a maximum of 20,000 RPM. Metalworkers, fabricators, and machinists rely on this style of wheel for inside contours, weld blending, and edge finishing where a flat grinding disc cannot reach.

This mounted flap wheel suits light industrial and job-shop environments where consistent surface conditioning is required on curved or irregular surfaces. It is particularly effective in pipe, tube, and structural steel fabrication. The coated aluminum oxide abrasive resists loading on ferrous metals and is well suited for moderate stock removal and blending passes. A single wheel is packaged per unit, making it easy to stock in quantity for production use or field service kits.

Key Features

• Aluminum oxide coated abrasive provides durable, consistent cut on ferrous metals
• 60 grit medium grade balances material removal with surface finish quality
• 3 inch diameter with 1 inch face width covers broad contact area on curved surfaces
• 1/4 inch shank mounts directly to standard die grinders and flexible shaft tools
• Cloth backing at XE weight adds flexibility for conforming to contours
• 20,000 RPM maximum rating suits high-speed rotary tools

Compatibility

Designed for use with rotary die grinders and similar tools accepting a 1/4 inch shank mounted abrasive wheel.

Installation Notes

Installation is performed by qualified metalworkers or tool operators familiar with abrasive wheel safety. Before mounting, confirm the tool spindle speed does not exceed the 20,000 RPM rating marked on the wheel. Thread the 1/4 inch shank securely into the collet of the die grinder and tighten per the tool manufacturer's guidance. Always wear appropriate eye and face protection and ensure workpiece is secured before operating.
