3M 7000045853 Convolute Deburring Wheel 8 in Aluminum Oxide

Product Description

The 3M 7000045853 is a convolute deburring wheel designed for aggressive edge finishing, burr removal, and surface blending on metal workpieces. Built with aluminum oxide abrasive at a hard density grade of 7, this wheel delivers consistent cut and finish across the full face width. It measures 8 inches in diameter with a 1-inch face width and a 3-inch center hole, and it is rated for a maximum speed of 4,500 RPM. Machinists, tool-and-die workers, and fabricators rely on this wheel type for controlled stock removal without the inconsistency of hand filing or flap wheels.

This wheel is suited for use in metalworking shops, fabrication facilities, and production environments where repeatable deburring is required. It is compatible with backstands, bench grinders, benchtop grinders, and inland sanders. The 3-inch center hole is compatible with mandrel and adapter number 356. Applications include deburring drilled holes, blending weld seams, and edge-breaking on ferrous and non-ferrous metals. The fine abrasive grade makes it appropriate for finishing passes where surface quality matters alongside burr removal.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety. Always power down and de-energize the grinder or backstand before mounting or changing the wheel. Verify that the machine spindle speed does not exceed the 4,500 RPM maximum rating marked on the wheel before operation. Follow ANSI B7.1 safe use and handling guidelines for abrasive wheels when mounting, guarding, and operating this product.
