3M 7000120680 Deburring Wheel 2 in Aluminum Oxide Density 8

Product Description

The 3M 7000120680 is an aluminum oxide unitized deburring wheel designed for aggressive material removal and surface finishing on metal workpieces. Measuring 2 inches in diameter with a 1/4 inch face width and a 1/4 inch center hole, this wheel operates at a maximum rated speed of 22,100 RPM. Density 8 with a hard grade construction means the wheel holds its shape under pressure, delivering consistent stock removal and edge-breaking performance across a range of metals. It is suited for machinists, fabricators, and metalworking technicians performing deburring, blending, and light surface conditioning tasks.

This deburring wheel is built for use with centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands. Its compact 2 inch diameter makes it effective in tight access areas and on smaller workpieces where larger wheels cannot reach. Compatible mandrel and adapter sizes are No. 3 and No. 5. Typical applications include deburring drilled holes, chamfering edges, and blending weld seams in both production shop and field maintenance environments.

Installation Notes

Installation and use should be performed by qualified machinists or metalworking technicians familiar with abrasive wheel safety. Before mounting, confirm the spindle speed of the tool does not exceed the 22,100 RPM maximum rating of the wheel. Inspect the wheel for damage before each use and ensure the mandrel and adapter are properly secured. Always wear appropriate eye protection and follow applicable ANSI B11 and OSHA abrasive wheel safety standards during operation.
