3M 7000045988 Convolute Deburring Wheel 8 in Aluminum Oxide

Product Description

The 3M 7000045988 is a convolute deburring wheel engineered for controlled material removal and surface conditioning on metal workpieces. Built with aluminum oxide abrasive at a hard density grade of 7, it delivers consistent cutting action while maintaining wheel integrity under load. Rated to a maximum of 4,500 RPM, this wheel suits high-throughput deburring, edge blending, and light stock removal tasks. Its convolute construction layers abrasive material uniformly around the core, providing an even finish across the full 1-inch face width. Licensed tradespeople and abrasives technicians working in production grinding or fabrication environments are the primary users of this wheel.

This wheel is suited for use on metalworking equipment in industrial and production shop environments. The 8-inch diameter and 3-inch center hole are sized for compatibility with centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands. It is compatible with mandrel and adapter type 356. Typical applications include deburring machined parts, conditioning 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 material removal.

Installation Notes

Installation and wheel mounting should be performed by a qualified operator familiar with abrasive wheel safety standards, including ANSI B7.1 guidelines for the use, care, and protection of abrasive wheels. Always power down and lockout the machine before mounting or removing the wheel. Verify that the machine spindle speed does not exceed the 4,500 RPM maximum rating marked on the wheel before starting the equipment. Inspect the wheel for cracks or damage before each use and never operate a damaged wheel.
