Norton 69957397885 Deburring Wheel 8 Inch Aluminum Oxide

Product Description

The NORTON 69957397885 is a convolute deburring wheel designed for use on bench grinders and pedestal grinders in metalworking and fabrication environments. Built with aluminum oxide abrasive at a density of 7 and a hard grade, this wheel delivers consistent material removal and surface finishing on metal workpieces. At 8 inches in diameter with a 1-inch face width and a 3-inch center hole, it mounts directly to standard grinder arbors and handles demanding deburring, blending, and edge-finishing tasks. The 3,650 RPM maximum speed rating keeps operation within safe limits on typical bench and pedestal grinder setups.

This wheel suits fabrication shops, machine shops, and maintenance operations where burr removal and surface conditioning are routine. It is appropriate for medium-duty deburring of ferrous and non-ferrous metals. The convolute construction compresses uniformly under load, which helps maintain consistent contact across irregular edges and contours. Machinists, welders, and metal fabricators are the primary installers and operators of this wheel type.

Key Features

• Aluminum oxide abrasive for reliable deburring and edge finishing on metal
• Density 7 hard grade construction for firm, consistent stock removal
• Convolute wheel design provides uniform compression and surface contact
• 3,650 RPM maximum speed rating for safe use on standard grinders
• 8-inch diameter with 3-inch center hole fits common bench and pedestal grinder arbors
• 1-inch face width suits general deburring and blending applications

Compatibility

Designed for use with bench grinders and pedestal grinders equipped with a compatible 3-inch arbor bore. Verify grinder spindle speed does not exceed the 3,650 RPM maximum rating before mounting.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician familiar with abrasive wheel safety. Disconnect and lock out power to the grinder before mounting or removing the wheel. Confirm the grinder spindle speed does not exceed the wheel maximum RPM rating, and always perform a ring test and a brief guarded run-in before full operation. Follow ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels.
