3M 7000077959 Mounted Flap Wheel 180 Grit Aluminum Oxide

Product Description

The 3M 7000077959 is a mounted flap wheel designed for surface finishing, blending, and deburring on metal and other hard materials. It combines non-woven and coated aluminum oxide construction to deliver consistent stock removal and a uniform finish. Rated to a maximum of 7,000 RPM, this wheel mounts via a Roloc+ attachment system for fast, tool-free changeovers on compatible die grinders and right-angle tools. At 180 grit in a very fine grade, it is suited for light deburring, edge blending, and pre-finishing passes where surface quality matters. Machinists, fabricators, and maintenance technicians are the primary users of this type of tooling.

This flap wheel is used in metalworking and fabrication environments, including weld blending on structural steel, finishing interior bores and curved surfaces, and deburring machined components. The 2.5-inch diameter and 1.25-inch face width make it effective on both flat and contoured workpieces. The very fine 180-grit rating positions it as a finishing-stage abrasive rather than a heavy material-removal tool. It is appropriate for both job-shop and production-line use wherever a die grinder is the tool of choice.

Key Features

• Roloc+ mount system for tool-free wheel changes on compatible grinders
• 180 grit, very fine grade aluminum oxide for surface finishing and light deburring
• Non-woven and coated abrasive construction for consistent cut and finish
• 7,000 RPM maximum speed rating for safe high-speed operation
• X-weight backing for durability under load
• 2.5-inch diameter and 1.25-inch face width suit both flat and contoured surfaces

Compatibility

Designed for use with die grinders and right-angle tools that accept the Roloc+ mount system.

Installation Notes

This wheel is installed and removed by a licensed or trained operator using the Roloc+ twist-lock system — no tools required for changeover. Always verify that the tool spindle speed does not exceed the 7,000 RPM maximum rating of the wheel before operation. Ensure the workpiece is secured and the grinder is powered off and unplugged before mounting or dismounting the wheel. Wear appropriate PPE including eye protection and gloves during use.
