3M 7100178230 Flap Wheel 2 in 60 Grit Aluminum Oxide

Product Description

The 3M 7100178230 is a 244D series flap wheel built for general-purpose grinding, polishing, sanding, and finishing on metal and similar surfaces. Constructed with aluminum oxide mineral abrasive, it cuts sharp and maintains cutting action throughout its service life. The flap design uses individually mounted abrasive flaps that continuously lap the work surface, helping achieve fine finishes without excessive material removal. The 1/4-20 arbor mount provides secure attachment to compatible mandrels and rotary tools. This wheel is suited for fabricators, maintenance technicians, and metalworkers who need consistent surface preparation results from a single tool.

The 244D flap wheel is used in general metal fabrication, weld blending, deburring, and surface conditioning applications. It is well suited for both shop and field use where a small-diameter wheel is needed to reach tight areas, contoured surfaces, or inside bores. The 2-inch diameter and 60-grit rating make it a practical choice for stock removal followed by intermediate finishing in a single operation. It is compatible with Type 83 (T83) and Type 84 (T84) mounting systems.

Key Features

• Aluminum oxide mineral abrasive cuts aggressively and lasts through extended use
• Individual flap construction continuously exposes fresh abrasive for consistent surface contact
• X-weight cotton cloth backing resists tearing and flexes to follow contoured surfaces
• Compatible with Type 83 (T83) and Type 84 (T84) mounting systems
• 60-grit rating suitable for stock removal and intermediate finishing
• 1/4-20 arbor mount for secure mandrel attachment

Compatibility

Designed for use with Type 83 (T83) and Type 84 (T84) mounting systems; fits standard 1/4-20 arbor mandrels used with rotary tools, drills, and die grinders.

Installation Notes

Installation is typically performed by machinists, fabricators, or maintenance trades using a die grinder or drill press. Ensure the tool is powered off and the chuck or collet is fully secured before mounting the wheel. Verify the tool RPM rating does not exceed the maximum RPM rated for the wheel. Eye protection and appropriate PPE should be worn during operation per applicable safety standards.
