3M 7000120787 Convolute Deburring Wheel 8 Inch Ao

Product Description

The 3M 7000120787 is a Scotch-Brite EX2 convolute deburring wheel designed for mid-range aggressiveness and hardness across a broad range of surface finishing operations. The convolute construction layers abrasive nylon web around a core, producing a dense, durable wheel that handles deburring, edge radiusing, blending, polishing, and light finishing in a single tool. The aluminum oxide abrasive mineral is well matched to ferrous and non-ferrous metal alloys. The wheel weighs 2.62 pounds and measures 8.71 inches in length by 8.51 inches in width by 4.83 inches in height. Metalworking shops, fabricators, and finishing technicians are the primary installers of this wheel type.

This deburring wheel is suited for bench grinder or pedestal grinder setups where consistent edge presentation is required. It performs best when fed continuously with sharp edges or metal burrs rather than intermittent or light contact. Typical applications include deburring machined parts, blending weld seams, radiusing cut edges, and surface finishing on metal alloys. It also sees use on many plastics and composites where controlled abrasion is needed without smearing or loading the wheel surface.

Key Features

• Convolute construction delivers consistent mid-range hardness and aggressiveness throughout wheel life
• Wheel edge can be dressed to restore cutting action for effective deburring, finishing, and polishing
• Bidirectional design operates clockwise or counterclockwise without performance loss
• Resists smearing for cleaner surfaces and reduced prep time between operations
• Minimizes heat buildup, reducing thermal impact on heat-sensitive workpieces
• Compatible with metal alloys, many plastics, and composites

Compatibility

Designed as an OEM-style replacement or direct-fit abrasive wheel for bench grinders and pedestal grinders accepting 8-inch convolute deburring wheels.

Installation Notes

Installation should be performed by a qualified metalworking or finishing technician following the grinder manufacturer's wheel-mounting procedures. Always power down and lock out the grinder before mounting or removing the wheel. Verify the grinder's rated RPM meets or exceeds the wheel's maximum operating speed before use. Inspect the wheel for cracks or damage prior to each use, and stand clear of the wheel plane during initial startup.
