3M 7000045890 Deburring Wheel 6 in Aluminum Oxide Medium

Product Description

The 3M 7000045890 is a convolute deburring wheel designed for aggressive edge conditioning, burr removal, and surface blending on metal workpieces. Built with aluminum oxide abrasive at a density 5, medium-grade construction, this wheel delivers consistent cutting action across a range of ferrous and non-ferrous metals. It measures 6 inches in diameter with a 2-inch face width and a 1-inch center hole, fitting standard arbors used on common grinding and finishing equipment. The 6,000 RPM maximum speed rating suits high-volume production and maintenance applications alike. Machinists, fabricators, and metalworking professionals use this wheel for finish deburring where repeatability and abrasive life matter.

This convolute wheel is suited for use on backstands, centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands. It fits residential shop and commercial fabrication environments where consistent deburring on cast, machined, or stamped metal parts is required. The medium-grade aluminum oxide abrasive handles moderate stock removal without overworking softer materials. Professionals working in metal fabrication, tool and die, and maintenance repair operations will find this wheel appropriate for edge prep and light surface conditioning tasks.

Key Features

• Aluminum oxide abrasive provides durable cutting action on ferrous and non-ferrous metals
• Density 5, medium-grade construction balances cut rate with surface finish quality
• Convolute wheel design maintains consistent abrasive exposure throughout wheel life
• 6,000 RPM maximum speed rating compatible with standard backstand and grinder equipment
• 1-inch center hole fits common arbor sizes on production grinding machinery
• Compatible with backstands, centerless grinders, die grinders, inline sanders, and pressure assist backstands

Compatibility

Designed for use on backstands, centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands. The 1-inch center hole and 6,000 RPM rating determine fitment to specific machine arbors and speed ranges — verify both before mounting.

Installation Notes

Mounting and operation of abrasive wheels should be performed by trained personnel following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Power down and lock out the machine before mounting or removing the wheel. Confirm the machine spindle speed does not exceed the 6,000 RPM maximum rated speed of this wheel before operation. Inspect the wheel for cracks or damage before each use and never operate a damaged wheel.
