3M 7000000747 Scotch-brite Exl Unitized Wheel 6 in Ao

Product Description

The 3M 7000000747 is a Scotch-Brite EXL Unitized Wheel designed for smoothing, deburring, and surface finishing on metal alloys, plastics, and composites. Built with aluminum oxide abrasive in a soft, conformable, layered construction, this 6-inch diameter wheel mounts on a 1/2-inch arbor and can be run clockwise or counterclockwise. The unitized structure maintains consistent performance throughout the life of the wheel and resists smearing, leaving cleaner surfaces with less prep work between operations. At 0.57 pounds, it is lightweight enough for extended bench or automated use.

This wheel is suited for fabrication shops, metalworking operations, and robotic finishing cells where consistent edge contact on complex or contoured parts is required. Typical applications include deburring cut edges, blending weld seams, and finish-polishing metal components before coating or inspection. Its ability to minimize heat buildup makes it appropriate for heat-sensitive substrates including certain plastics and composite materials. Machinists, tool and die technicians, and metal fabricators are the primary users in both manual and automated processing setups.

Key Features

• Soft, conformable construction maintains abrasive contact on complex and contoured part geometries
• Unitized layered build allows bidirectional operation — clockwise or counterclockwise
• Resists smearing for cleaner surface results and reduced preparation time
• Minimizes heat buildup, reducing risk of thermal damage to heat-sensitive materials
• Wheel edge can be dressed for targeted deburring, finishing, and polishing
• Suitable for metal alloys, plastics, and composites in both manual and robotic applications

Compatibility

Designed for use on bench grinders, angle grinders, and automated finishing equipment accepting a 1/2-inch arbor and 6-inch diameter wheel.

Installation Notes

Installation should be performed by a qualified machinist or fabrication technician. Power down and lock out the grinder or finishing machine before mounting the wheel. Confirm arbor size and wheel speed rating match the machine specifications before operation. Follow ANSI B7 safety standards for abrasive wheel mounting and guarding.
