3M 7000046076 Scotch-brite EX2 Deburring Wheel 8 Inch Fine

Product Description

The 3M 7000046076 is a convolute-constructed deburring wheel from the Scotch-Brite EX2 line, designed for mid-range aggressiveness and hardness across a wide range of metalworking and surface finishing tasks. This wheel handles deburring, edge radiusing, blending, polishing, and finishing on metal alloys, many plastics, and composite materials. It weighs 1.28 pounds and measures 8.7 inches in length and width with a 4.2-inch height profile. Fabricators, machinists, and finishing technicians use it on bench grinders and standalone deburring machines where consistent contact with burrs or sharp edges is maintained throughout the operation.

This wheel suits production and maintenance shop environments where repeated deburring of metal parts is required. Its convolute layered construction delivers predictable, repeatable results on ferrous and non-ferrous alloys, as well as select plastics and composites. The wheel is well suited for bench-mounted applications in fabrication shops, machine shops, and manufacturing facilities where surface finishing quality and heat control are priorities.

Key Features

• Convolute layered construction operates in both clockwise and counterclockwise directions for flexible machine mounting
• Wheel edge can be dressed to maintain effective deburring, finishing, and polishing performance
• Mid-range hardness provides a balance between conformability and aggressive material removal
• Resists smearing for cleaner finished surfaces and reduced prep time
• Minimizes heat buildup to protect heat-sensitive base materials during operation
• Suitable for all metal alloys and many plastics and composites

Compatibility

Designed for use on bench grinders and deburring machines that accept convolute-style abrasive wheels with an 8-inch diameter form factor. Performs best when consistently presented with sharp edges or metal burrs.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician following the machine manufacturer's mounting specifications. Power down and lock out the grinder or deburring machine completely before mounting or removing the wheel. Confirm the machine's rated RPM does not exceed the wheel's marked maximum operating speed before use. Inspect the wheel for visible damage before each use and dress the edge as needed to restore cutting geometry.
