3M 7000120543 Deburring Wheel 3 Inch Aluminum Oxide

Product Description

The 3M 7000120543 is an aluminum oxide unitized deburring wheel designed for aggressive deburring, blending, and surface conditioning on metal workpieces. With a density rating of 7 and a hard density grade, this wheel delivers consistent cut and finish across repeated passes without loading or glazing. The wheel measures 3 inches in diameter with a 0.5-inch face width and a 0.25-inch center hole. It is rated for a maximum speed of 15,100 RPM. Fabricators, tool and die technicians, and metalworking professionals use this wheel to remove burrs, sharp edges, and surface irregularities left by machining, cutting, or grinding operations.

This unitized deburring wheel suits a range of metalworking environments, from production floor finishing to bench-level part prep. Its compact 3-inch diameter and 0.25-inch arbor hole make it compatible with die grinders and inline sanders used in tight or hard-to-reach areas. It also fits centerless grinders, manual backstands, and pressure assist backstands for higher-volume deburring applications. The aluminum oxide abrasive is well suited for ferrous metals and hard alloys where consistent stock removal and edge refinement are required.

Installation Notes

This wheel is installed by a machinist, fabricator, or toolroom technician using an appropriate mandrel matched to the 0.25-inch center hole. Before mounting, verify that the spindle speed of the tool does not exceed 15,100 RPM. Inspect the wheel for cracks or damage before each use and never operate a damaged wheel. Follow ANSI B7.1 safety standards for the mounting and use of abrasive wheels.
