3M 7100178230 Mounted Flap Wheel 60 Grit 1 Inch

Product Description

The 3M 7100178230 is a mounted flap wheel designed for rotary grinding, blending, and finishing tasks on metal, wood, and composite surfaces. The wheel uses aluminum oxide abrasive on a coated cloth backing with an XE backing weight, providing durable cut and consistent scratch patterns across a 1-inch face width. Rated for medium grade work at 60 grit, it is well suited to deburring, edge blending, and surface preparation in fabrication and maintenance environments. The threaded mount allows direct attachment to die grinders and rotary tools. Machinists, fabricators, and maintenance technicians are the primary users.

This mounted flap wheel fits common small-diameter die grinder arbors via its threaded mount. It is used in both production and MRO settings for inside-diameter finishing, weld blending, and contour work on irregular surfaces. The 1-inch face width makes it effective in narrow channels, bores, and tight profiles where flat abrasive tooling cannot reach. It is equally applicable to bench or handheld rotary tool setups.

Key Features

• 60 grit aluminum oxide abrasive for medium-grade material removal and surface blending
• 1-inch face width suits narrow profiles, bores, and contoured workpieces
• Coated cloth backing with XE backing weight for flexibility and durability under load
• Threaded mount for direct installation on die grinders and rotary tools
• 25,000 maximum RPM rating supports high-speed rotary tool use
• No interleaf construction for consistent abrasive contact across the full flap

Compatibility

Designed for use with threaded-arbor die grinders and rotary tools accepting a standard threaded mounted abrasive wheel. Verify arbor thread size matches before installation.

Installation Notes

Installation is performed by qualified machinists or maintenance technicians using standard rotary tool setups. Always power down and disconnect the die grinder before mounting or removing the wheel. Confirm the tool spindle speed does not exceed the 25,000 RPM rating of the wheel before operation. Inspect the wheel for damage before each use and never operate a cracked or deformed flap wheel.
