3M 7000028472 Convolute Deburring Wheel 6 in Aluminum Oxide

Product Description

The 3M 7000028472 is a convolute deburring wheel designed for aggressive material removal and surface conditioning on metal workpieces. Built with aluminum oxide abrasive at a density 7 hard grade rating, it delivers consistent cutting action across the full face of the wheel. The 6-inch diameter and 1-inch face width suit a range of stationary and handheld power tools. This wheel is rated to 6,000 RPM and is intended for use by machinists, tool and die professionals, and fabricators who need reliable edge deburring and surface blending on production runs or bench work.

This convolute wheel fits applications in metalworking shops where burr removal, edge radiusing, and light surface blending are routine operations. The 1-inch center hole accommodates standard arbors, and the wheel is compatible with mandrel types 3 and 5. Typical install scenarios include mounting on centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands. The coarse aluminum oxide construction is suited to ferrous and non-ferrous metals where a fast cut and defined edge break are required.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician following ANSI B7.1 safe use guidelines for abrasive wheels. Always power down and de-energize the tool before mounting or removing the wheel. Confirm the tool spindle speed does not exceed the 6,000 RPM rating marked on the wheel. Inspect the wheel for cracks or damage before each use and never force the center hole onto an oversized arbor.
