3M 7000120556 Deburring Wheel 3 in Aluminum Oxide Density 5

Product Description

The 3M 7000120556 is a unitized deburring wheel designed for metal finishing, edge deburring, and surface blending in fabrication and machining environments. Built with aluminum oxide abrasive at a density grade of 5, this wheel delivers consistent medium-cut action suitable for removing burrs, light scale, and surface irregularities without aggressive stock removal. It measures 3 inches in diameter with a 1-inch face width and a 1/4-inch center hole. Rated to a maximum of 15,100 RPM, it is well-suited for high-speed portable and stationary tool applications. Installation and operation are handled by machinists, fabricators, and metalworking technicians.

This wheel is intended for use in metal fabrication shops, tool rooms, and production finishing operations. Its 1/4-inch arbor hole makes it compatible with common rotary tool setups and inline configurations. Typical applications include edge finishing on stamped, machined, or welded components where controlled material removal and a consistent surface finish are required.

Key Features

Installation Notes

This wheel should be mounted and operated by qualified machinists or metalworking technicians familiar with abrasive wheel safety. Before mounting, verify that the tool spindle speed does not exceed the 15,100 RPM maximum rating of the wheel. Inspect the wheel for damage before each use and ensure the arbor nut is properly secured. Always use appropriate eye and face protection when operating abrasive wheels, in accordance with ANSI B11 and relevant shop safety standards.
