3M 7100178245 Mounted Flap Wheel 60 Grit Aluminum Oxide

Product Description

The 3M 7100178245 is a mounted flap wheel abrasive designed for precision grinding, blending, and finishing on metal and other hard surfaces. It carries a 60-grit, medium-grade aluminum oxide coated abrasive bonded to a cloth backing with an XE backing weight, delivering consistent material removal in tight areas and contoured workpieces. The threaded mount allows direct attachment to rotary tools, die grinders, and similar power equipment. Maximum rated speed is 30,000 RPM. This wheel is a single-unit consumable used by machinists, fabricators, and maintenance technicians wherever controlled surface finishing is required.

This mounted flap wheel is suited for deburring, surface blending, and weld seam cleanup on metal components. The threaded mount style makes it appropriate for use in recessed bores, internal diameters, and areas where flat grinding wheels cannot reach. It is commonly used in light manufacturing, maintenance and repair operations, and metal fabrication shops. The 1-inch face width provides adequate contact for small to medium workpiece features without sacrificing control.

Compatibility

Designed as a threaded-mount flap wheel for use with die grinders and rotary tools that accept a compatible threaded mandrel. Verify mandrel thread size and tool RPM rating before installation.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician familiar with abrasive tooling. Power down and unplug the tool before mounting or removing the flap wheel. Confirm the tool's rated RPM meets or exceeds the 30,000 RPM maximum rating of this wheel before operation. Inspect the wheel for damage before each use and never operate a cracked or deformed abrasive accessory.
