3M 7000045982 Convolute Deburring Wheel 8 Inch Fine Grit

Product Description

The 3M 7000045982 is a convolute-constructed deburring and finishing wheel designed for mid-range aggressiveness and hardness across a broad range of surface preparation tasks. Built with a layered, unitized construction, this wheel handles deburring, edge radiusing, blending, polishing, and finishing on metal alloys, plastics, and composites. At 8.71 inches in length and 8.51 inches in width with a 4.83-inch height profile, the wheel weighs 2.58 pounds. It is suited for bench grinder and pedestal grinder setups and is installed and serviced by machinists, fabricators, and metalworking professionals in production and job-shop environments.

This wheel is well-suited for finishing operations on all common metal alloys as well as many plastics and composites. Its fine grit rating makes it appropriate for final deburring passes, light edge radiusing, and surface blending where a cleaner finish is required without heavy stock removal. The wheel edge can be dressed to maintain consistent performance. It operates in both clockwise and counterclockwise directions, allowing it to run on a variety of bench and pedestal grinder configurations found in fabrication shops, maintenance facilities, and light manufacturing settings.

Key Features

• Convolute layered construction delivers consistent mid-range aggressiveness and hardness throughout wheel life
• Operates clockwise or counterclockwise for flexible grinder compatibility
• Wheel edge can be dressed to maintain sharpness for effective deburring and finishing
• Resists smearing for cleaner surfaces and reduced prep time between operations
• Minimizes heat buildup, making it suitable for use on heat-sensitive materials
• Effective on all metal alloys and many plastics and composites

Compatibility

Designed as a convolute deburring and finishing wheel for use on bench grinders and pedestal grinders where an 8-inch diameter wheel is specified. Suitable for deburring and finishing metal alloys, many plastics, and composites.

Installation Notes

Installation should be performed by a qualified operator following the grinder manufacturer's mounting instructions and applicable ANSI B11 or OSHA abrasive wheel safety standards. Power down and lock out the grinder before mounting or removing the wheel. Confirm arbor size compatibility and maximum operating RPM before use. Always dress the wheel edge with an appropriate dressing tool before initial use and periodically during service to maintain consistent cutting performance.
